Definitions
- the present invention relates to the field of electric motors, and in particular electric motors for fans.
- patent application WO2003081755 is known in the prior art, which relates to a stator intended for an electric motor, in particular for a high-power low-voltage motor of the external armature motor type, and which comprises a stack of stator laminations provided with a multitude of stator grooves and stator teeth for housing stator windings, as well as an interconnection system for interconnecting winding wires of the stator windings.
- the stator windings wound around the stator teeth through the stator grooves overhang the stack of stator laminations of a winding head on both end faces.
- the interconnection system consists of winding contact elements as well as interconnection contact elements, the interconnection contact elements at least being arranged on one end face of the stator lamination stack substantially within a space delimited by the stator windings and by a plane defined by the winding head.
- Patent application US2012098363 describes a stator of an electric motor having phase potential bars and an insulating retaining element.
- the insulating retaining element includes a first component configured to receive the phase potential bars and to electrically insulate the phase potential bars from each other.
- the insulating retaining element further includes a second component separate from the first component. The second component, in conjunction with the first component, forms a cup that borders the phase potential bars.
- the prior art solutions are not entirely satisfactory because they provide either to seal the entire motor assembly and therefore pose a problem for cooling the coils, or to place only the electronic card in a sealed compartment and therefore to seal the rigid and discrete conductors connecting it to the winding phases.
- the prior art solutions provide to place the connections in a separate sealed enclosure.
- the invention proposes an increase in the number of passages between the two spaces, and therefore the risk of loss of sealing in the event of deterioration of one of the sealing joints.
- the object of the present invention is to overcome these drawbacks by combining radial connections which lead into a watertight chamber with a separate chamber containing a printed circuit board.
- This motor comprises a rotor and a stator comprising a plurality of coils interconnected with an electronic card in a sealed area, said electronic card being housed in a compartment separated from the coils of the stator on the one hand and from the rotor on the other hand by a transverse partition or a transverse part,
- said frontal annular partition is an extension of said stator support, and is closed by a transverse partition to form the chamber.
- annular partition is associated with a deformable seal to achieve the sealed radial passage of said pairs of wires.
- said annular partition has two crowns defining between them an annular groove in which said deformable seal is housed, said crowns being provided with slots for the passage of said wires.
- said deformable seal is a toric part having a lower part formed of two coaxial lips, straddling said peripheral crown, one of the lips being inserted into the annular groove.
- said toric part is also provided with indentation slots covering the sides of the slots of the crown, said indentation slots being narrower than the wires to force a deformation of the toric part at the time of insertion of the wires.
- the bottom of said slots of the crown has a projection to form a stop during the axial insertion of said wires through the slots.
- At least one complementary annular seal is associated with said deformable seal to close the passage of said wires.
- the rotor is housed within the stator.
- stator support produces coil bodies by overmolding the stator teeth.
- the coils are made by winding the wires directly onto said coil bodies of the stator support.
- the magnetic body of the stator is made up of the assembly of the teeth with a stator crown, the whole being secured by means of the stator support.
- stator is housed inside the rotor.
- the invention also relates to a method of manufacturing an electric motor integrating one or a combination of the preceding characteristics for which all the coils are produced sequentially and without interruption of the wire between two coils.
- the embodiment described concerns an electric motor used for forced ventilation functions, and particularly that of polyphase motors with electronic commutation with pilot control integrated into the motor housing and coils exposed to the air flow to allow optimum cooling, while sealingly protecting the connection portions and the electronic pilot device, so as to avoid short circuits during immersion, if necessary.
- the solution that is the subject of the present invention is particularly interesting for the construction of high-power ventilation motors (greater than 1 KW) used for cooling the components of electric vehicle fast charging devices, but it can be used for any type of ventilation drive motor or pump with integrated electronics, making it possible to benefit from the fluid flow to cool the stator coils located in the space exposed to the air flow without any risk of contamination for the sealed areas facing the external environment. It is also possible to create a sealed area that encompasses the rotor to guarantee reinforced protection by taking advantage of the overmolding of the stator, by adding a part that closes this cavity and which can also serve as a rotor guide.
- the invention is distinguished in particular by the embodiment of the sealed closure zone at the level of the insulated winding wires, so as to ensure that no bare zone can be exposed to splashes or to water intrusion during the immersion phase of the motor. It is then possible to have windings exposed to the air flow to best evacuate the heat produced by the iron losses and copper losses of the motor, without risking a short circuit.
- the two sealed spaces, the one containing the connection portions and the one containing the electronic control device can have passages from one to the other through the wall of the housing because this does not compromise the protection of all the sensitive elements located inside one or the other of these spaces.
- Figures 1 to 10 illustrate a non-limiting exemplary embodiment described in detail below.
- FIGs 2 and 5 show a detailed view of the stator (100). It is constituted by a stator support (150) more particularly represented by figures 3 and 4, and a stator crown (110) formed by a pack of sheets each having an annular cutout, the representing the stator before assembly of the stator crown (110) on the stator support (150).
- the stator support (150) is formed by overmolding, by injection of a plastic material, a set of radial teeth (120) also formed by one, or possibly several, packs of sheets.
- This overmolding makes it possible to form spaces, called coil bodies (140), making it possible to produce the winding generating the magnetic field interacting with the rotor (200).
- Said coil bodies (140) extend radially from an annular casing (141), the inner surface of which is coplanar with the front of the teeth (120) and which extends axially on either side of the teeth over the desired coil height so as to provide a frontal support zone for the wires of the coils (130).
- said annular casing (141) defines a receiving cavity (158) for the rotor visible on the .
- the radial extension of the coil bodies is done along the teeth (120) with a minimum thickness allowing to maximize the space intended for the coils (130) while ensuring the electrical insulation between the coils (130) and the stack of sheet metal of the teeth (120).
- the coil bodies (140) are extended at their outer end by an annular sector (142), adjoining the outer surface of the teeth (120), and of the same axial extent as the annular envelope (141) so as to provide distal support for the wires of the coils (130).
- peripheral annular sectors (142) are not contiguous between the teeth (120), but leave a free angular sector (143) to facilitate the routing of the needle during the winding operation.
- these coil bodies (140) are grooved so as to guide the wires and facilitate winding, this is particularly interesting in the case of winding wires of large section and therefore of great rigidity.
- the annular sectors (142) of the coil bodies (140) are radially extended in their upper part by “U”-shaped protrusions (145) whose legs extend in the direction of the teeth. Some of these protrusions (145) are provided with flexible extensions (156) extending axially beyond the opposite end of the teeth, these flexible extensions (156) being terminated by hooks so as to ensure the retention by clips of the stator crown once the latter is assembled to the stator support (150).
- stator ring (110) is positioned by an axial insertion, so that the outer surface of the teeth (120) comes into mechanical and magnetic contact with the inner surface of the stator ring (110) to ensure the closing of the magnetic flux.
- the stator ring is then held in position by the flexible extensions (156).
- part or all of the protrusions (145) have a protuberance (157) ensuring the connection by rolling with the transverse part (300).
- stator support (150) has an inner core closed by a transverse partition (151) crossed by an axial passage (152). This axial passage (152) is crossed by a central shaft (350) intended for guiding the rotor (200).
- a housing (153) is provided to receive an O-ring (220) type seal (O RingTM) to seal the upper part in a sealed manner.
- the central shaft is fixedly mounted in a guide nose (330) of the transverse part (300), this guide nose (330) being inserted into the axial passage (152) during assembly of the transverse part (300) on the stator support (150).
- the upper surface of the transverse partition (151) has protrusions (154) constituting plastic rivets for fixing by plastic riveting of the inter-coil connection tracks (610, 620, 630) which will be detailed below.
- Protrusions (155) having a tapped hole are intended to receive screws for fixing the transverse part (300).
- the transverse partition (151) is surrounded at its periphery by a frontal annular partition (160) extending perpendicular to its surface to form a sealed chamber (170) in which the inter-coil connections and the stripped areas of the wires are enclosed, while the wire outside this chamber (170) is always insulated and continuous.
- the front annular partition (160) provides a sealed passage function for the pairs of wires extending radially from the coils (130) to reach the sealed chamber (170).
- each coil has a pair of wires passing through the front annular partition (160).
- two or more coils are connected in series by a continuous and unstripped wire, and in this case, the connecting wire between the coils does not need to pass back through the sealed chamber (170), thus the pair of wires extending radially will correspond to all the coils in series.
- the winding of the teeth is carried out by a single continuous wire, successively running through the coils and forming loops inside the chamber (170), where the wire surrounds interconnection support pads (650). It is nevertheless also possible to provide independent coils, wound separately, inserted radially on the teeth of the support, with the wires arranged radially through said front annular partition (160).
- the frontal annular partition (160) has two concentric rings (161, 162) defining an annular groove (163).
- the rings (161, 162) are indented by radial slots (164, 165) respectively to allow the radial passage of the wires (131) of the coils (130) and their guidance at the time of winding the stator support (150).
- the top of the peripheral ring (162) has anchoring housings (166) for the engagement of hooks (185) for positioning and hooking a deformable indented toric part (180), for example made of elastomer.
- This toric part (180) has a lower part formed of two coaxial lips (181, 182), straddling said peripheral crown (162), the lip (182) being inserted into the annular groove (163), and an indented upper part being locally crossed by the radial wires of the coils (130), the width of the indentation slots (183) being less than the section of the winding wire (131) to ensure a sealed pinching of the wire.
- This toric part (180) has on either side of each indentation slot (183) a cavity (184) opening onto the adjacent slot (183) to allow filling with glue or resin ensuring sealing after insertion of the winding wires (131).
- the bottom of the slots (165) of the peripheral crown (162) each have a projection (167) of the same width as the cavities (184) to form a support for the winding wire (131) and prevent it from causing shearing of the bottom of the toric part (180) during winding and a potential loss of sealing of the front annular partition (160).
- the sealing of the chamber (170) is perfect by an additional seal (800), for example made by depositing a glue or silicone, placed between the periphery of the front annular partition (160) and the transverse part (300).
- the annular configuration of the toric part (180) makes it possible to deposit this seal (800) on its entire upper face in a single continuous dosage so as to ensure perfect sealing while limiting its production cost.
- the transverse part (300) has an annular protrusion (320) of a shape complementary to that of the frontal annular partition (160), or to the toric part (180) covering it, to ensure a sealed peripheral barrier of the chamber (170).
- the annular groove (163) between the rings (164, 165) could be filled by a deposit of glue or silicone that can be driven inside the slots (164, 165) by piston effect during assembly with the transverse part (300) thanks to a shape complementary to said space and located on said transverse part.
- This second solution would nevertheless be more expensive because it would require a much larger deposit of glue, a material known to be expensive.
- Other alternatives would be the deposit of a crown of resin or silicone on the stripped area of the wires (131), or even that the peripheral ring does not surmount the surface of the stator support, but is a frontal annular partition formed on the lower surface of the transverse part (300).
- the electronic card (400) is housed in a sealed chamber (310) separate from the chamber (170), the two chambers communicating with each other.
- An alternative embodiment consists of providing only one chamber (170), the volume of which is sufficient to house both the interconnection of the coils and the electronic card (400).
- a closing cover (500) seals the chamber (310) in a sealed manner.
- the motor has three phases, resulting in an interconnection of the coils for groupings by means of an electrical circuit (600) formed of three metal tracks (610, 620, 630).
- the wire (131) alternately passes through the coils (130) and the electrical circuit (600) during winding by an automaton, without breaking the wire.
- the wire (131) is anchored at a starting point (640) consisting of a flared shape in which the start of the wire is engaged and held by wedging. It then passes radially through the front annular partition (160) successively through slots (164, 165) provided in the crowns (161, 162), and then winds a first tooth (120), before radially joining the chamber (170) by passing again successively through other slots (165, 164) of the front annular partition (160). Inside the chamber (170), it goes around a support pad (650) of a first track (610), before returning radially towards another coil (130) adjacent to the previous one, after having passed through the front annular partition (160) through yet other slots (164, 165).
- the wire (131) then winds the second tooth, before radially joining the chamber (170) by passing again through slots (165, 164) of the front annular partition (160). Inside the chamber (170), it goes around a support pad (650) of a second track (620), before returning radially towards another coil (130) adjacent to the previous one; and so on.
- Each support pad (650) is associated with a deformable lug (660) which is folded back, after the passage of the wire (131), against the wire (131) surrounding the support pad (650) to provide a welding point locally removing the insulation coating of the wire.
- the support pads (650) and the lugs (660) are produced by local deformations of the metal track (610, 620, 630).
- the wire (131) passes through the front annular partition (160) before and after each coil (130).
- the wire (131) passes through the front annular partition (160) only to ensure the connections between a coil and a track (610, 620, 630), but not for the direct connections of two coils (130), in order to reduce the passages and therefore the possible sources of leaks.
- the embodiment described provides for a rotor architecture guided by two ball bearings (230, 240) inserted in the rotor yoke (210) consisting of a stack of sheets, axially spaced apart to ensure its stability.
- the outer rings of the ball bearings (230, 240) are both tightly mounted in the rotor yoke (210) constituting the rotor yoke. Note that in figures 1, 4 and 10 the sheets are not shown to improve readability.
- the inner rings of the ball bearings (230, 240) are slidably mounted on the central shaft (350).
- the rotor yoke (210) has, for the sheets located at the level of the bearings (230, 240), recessed areas (215) with a non-circular central cutout (216) to ensure radial elasticity allowing the insertion of the outer ring of the bearing by fitting and elastic deformation of the bearing housing.
- the other sheets have a simple circular central cutout, with an internal diameter less than the external diameter, e, of the outer ring of the bearings (230, 240), but greater than the diameter d of the central shaft (350), so as to form an axial stop (213, 214) for the bearings (230, 240).
- the central shaft (350) is fixed and secured to the transverse part (300) into which it is forced or overmolded, or secured by any other known means.
- the final height of the rotor (200) plus stator (100) assembly is optimized because it is then possible to fix the propeller, not shown, directly in the rotor yoke (210) formed from a pack of sheets through flanges (250) provided with claws (260) for holding the magnets (270), and thus to eliminate the lower flange which holds the front bearing of the rotor as can be the case with known solutions of the prior art.
- the propeller (900) is not driven by the central rotor guide shaft (350), but by a direct connection with the rotor yoke (210).
- the fixing points of the propeller (900) on the rotor yoke (210), which must allow the transmission of the drive torque, can be freely positioned on a diameter which can be larger than the diameter of the central shaft (350), since the only constraint is to remain registered in the interior of the rotor yoke (210) or of a flange (250) for holding the magnets (270) which can be attached to it.
- This positioning diameter, D is of the same order of magnitude as the positioning diameter of the magnets (270) and therefore much larger than the diameter d of the fixed central shaft (350) or of the bearings which can be of small dimensions to reduce their cost.
- the assembly of the bearings (230) and (240) is called an “O” assembly and makes it possible to move the centers of force away from the bearings for greater stability of the rotating assembly.
- the propeller (900) can be a large-diameter part and can rotate quickly, the correct balance of the masses of this part is necessary.
- axial fingers (910) of the propeller are able to be inserted around the outer ring of the bearing (240), in recessed areas (218) of the rotor sheet metal pack. This gives very good concentricity of the propeller relative to the axis of rotation of the rotor (200).
- the axial fingers (910) have a beveled end so as to facilitate their insertion into the recessed areas (218).
- the propeller (900) is preferably molded in a single part in order to control the geometric tolerances between the different surfaces.
- the propeller (900) is secured to the rotor by means of fixing screws (920).
- an external rotor (200) differs in that the rotor (200) is not fully housed within the stator, but extends axially from the receiving cavity (158), where it is guided on the central shaft (350) by means of the bearings (230, 240), to envelop the stator lamination packs by defining a bell (250).
- the magnets (270) of the rotor (200) line the internal cavity of this bell (250) to face the teeth (120).
- the stator crown (110) then joins the teeth (120) on their inner end.
- This embodiment differs from the previous embodiments in that the electronic card (400) and the electrical circuit (600) are housed in a single chamber (170).
- the transverse part (300) is then an integral part of the stator support (150) and the sealing of said chamber (170) at the level of the frontal annular partition (160) is ensured by the use of an annular shape (380) interposed between the transverse part (300) and the closing cover (500).
