Definitions
- the invention relates to a stator for an electric machine according to the preamble of
- the invention further relates to a manufacturing method for a stator and an electric machine for a motor vehicle.
- An electric machine is generally understood to mean an electromechanical converter which converts electrical energy into mechanical energy and / or mechanical energy into electrical energy.
- An electric machine is in particular an electric motor (electric motor) and / or generator with a fixed stator or stator and a rotatably mounted in the stator rotor or rotor (inner rotor).
- the stator has a stator or
- the stator body may be formed from individual stator laminations, which are combined to form a so-called laminated stator core.
- the prior art is made to DE 10 2008 007 578 A1.
- stator laminations can be perforated, wherein the perforations in the laminated stator core are axial
- Stator sheets are provided. This is shown, for example, in US 6,088,905 A (see
- the object of the invention is to provide a trained with axial bores or axial bores stator, which is space and weight optimized.
- stator according to the invention has a stator body formed from individual stator laminations, which is formed with axial bores, in particular through-bores, wherein the stator body is provided with (radially projecting) on its outer circumferential or circumferential surface.
- Projections is formed, in which the axial bores are arranged.
- a plurality of projections distributed over the circumference are provided, wherein in each projection at least one axial bore is formed.
- the projections preferably extend over the entire axial length of the stator body or of the stator lamination stack formed from the stator laminations. Since there are voids between the projections, considerable space and weight or mass can be saved with the invention.
- a first embodiment provides that the individual stator laminations, in particular all the stator laminations, are formed on the outer circumference with perforated, ear-like tabs which are aligned one above the other in the laminated stator core and form the projections.
- the projections are by means of interlocking form-locking elements on
- the interlocking elements may be designed for an undercut connection, preferably with a Verastungsgeometrie, which allows snapping by pressing.
- the positive locking elements are
- the projections can, in particular in one piece, be formed from metal, for example aluminum, or plastic, also fiber-reinforced plastic. Preference is given to injection-molded parts or cut extruded profile parts.
- the second embodiment is particularly advantageous for a dip-impregnated stator.
- the entire stator is immersed in an impregnation medium, such as resin, and soaked. Subsequently, the resin is cured by supplying energy.
- the immersion impregnation allows a fixation of the stator laminations and a coating of the stator body and stator winding in a single process step.
- Impregnation can also serve the sealing.
- the prior art is on the
- the production of an impregnated and in particular dip-impregnated stator can then comprise, for example, the following steps:
- Impregnating and in particular dip impregnating the stator preferably by
- Projections or the stator are heated or residual heat can be used by hot curing.
- the projections attached subsequently to the impregnation process are thus resin-free on their outer surfaces, which may in particular act as contact surfaces or support surfaces, and on end surfaces, which may furthermore function in particular as screw head support surfaces.
- ZSB stator assembly stator
- the stator can thus be installed without additional processing and, for example, be installed in a housing.
- Fig. 1 shows an axial plan view of a stator with projections.
- Fig. 2 shows an axial plan view of a section of another stator body with separately formed projections.
- Fig. 3 shows a perspective view of a projection formed as a separate part for attachment to the stator shown in Fig. 2.
- the stator body or carrier 100 shown in FIG. 1 is approximately circular cylindrical and is formed from a plurality of identical stator laminations 110, which are stacked in the axial direction L (perpendicular to the plane of the page) and form a laminated stator core.
- the stator winding grooves 120 for receiving a stator winding not shown are formed on the inner circumferential surface (internally-grooved stator).
- stator body 100 On its outer peripheral surface, the stator body 100 is formed with four protrusions 130 through which axial through holes 140 extend.
- the through holes 140 are, for example, for the attachment of end plates or end caps, bearing caps or
- the through holes 140 may also be provided for mounting the stator in a housing.
- the projections 130 may also be used as attachment or
- the stator body 100 further includes a dip impregnated resin impregnation 150, which is only partially illustrated.
- each stator lamination 10 has four tabs or ears 15 which are radially outwardly projecting and perforated and which form the projections 130 in the laminated stator core.
- all projections 130 are formed as separate parts or body 135 which are secured by means of dovetail 160 form-fitting manner on the outer peripheral surface of the stator 100 also formed of stator laminations.
- the axial length of the separate projections 130/135 corresponds to the axial length of the stator body or the stator lamination 100.
- Dovetail connection 160 extends over the entire axial connection length.
- FIG. 3 shows such a projection 130 formed as a separate part, which is already formed with a through-bore 140, with support surfaces 138 adapted to the outer circumferential surface of the stator body 100 and with a dovetail-shaped groove 137. (The other separate projections 130 are identical.)
- the stator 100 is formed with corresponding Nutzapfen 107, resulting from a corresponding
- the Nutzapfen 107 and the groove 137 form corresponding form-fitting elements.
- the projections 130 formed as separate parts 135 are preferably fastened to the stator body 100 only after a possible impregnation and are thus resin-free (ie the contact surfaces functioning as housing contact surfaces and / or as screw head contact surfaces are free of impregnation). Manufacturing tolerances can be better adhered to, in addition, the protrusions 130 are also free of resin drops and resin runners.
