Definitions
- the present invention relates to a rotating electrical machine and its control method.
- the rotating electrical machines are formed of a rotor and a stator, one of these elements generating a rotating magnetic field so as to drive the other element in rotation.
- the stator is generally formed of several winding phases distributed over its periphery and fed successively so as to form the rotating magnetic field.
- the rotor carries a winding which must be traversed by a current having an intensity greater than a given value in order to be sufficiently magnetized to be driven by the rotating magnetic field.
- the patent application FR 2,875,556 describes for example a solution to anticipate as much as possible the need to start the electric machine and therefore the need to perform a pre-magnetization phase.
- the starting of the electric machine by the excitation of the stator is realized with a predetermined delay (150 ms in the given example) with respect to the beginning of the pre-magnetization.
- This delay is calculated to ensure sufficient magnetization of the rotor in the various electrical conditions encountered by the system and the pre-magnetization time is therefore not optimal, particularly in systems where a reservoir of energy is used. causes a variable voltage in fairly large proportions, but also because of the uncertainty existing on the electrical values in any type of system.
- the invention proposes a rotating electrical machine comprising a first element capable of generating a rotating magnetic field with respect to the first element and a second element provided with a winding able to be traversed by a current so that the rotating magnetic field drives the second element in rotation, characterized by means for measuring an electrical quantity at least connected to said current and means for initiate the generation of the rotating magnetic field at a given instant as a function of the measured electrical magnitude.
- said electrical quantity is said current.
- the means for initiating the generation of the rotating magnetic field are, for example, suitable in this case for initiating said generation when the measured current reaches a threshold value, which makes it possible to carry out a pre-magnetization phase precisely limited to what is necessary to obtain optimal magnetization of the rotor.
- the electrical quantity is a voltage applied to said winding.
- the means for initiating the generation of the rotating magnetic field are, for example, then capable of initiating said generation after a period of application of said determined voltage as a function of the measured electrical quantity, which also makes it possible to adapt the duration in order to obtain optimal premagnetization.
- the rotating electrical machine is arranged to be integrated in a variable voltage system that can vary between two limit values, for example between 14V and 28V or between 12V and 25V.
- This system may, if necessary, be arranged to be able to store electrical energy from a braking of the vehicle, in particular using one or more super-capacitors.
- the invention is particularly well suited to this type of system because it makes it possible to optimize the pre-magnetization time as a function of the voltage which is variable. In particular, when the vehicle's on-board network voltage is high, the time for the pre-magnetization can be reduced compared to the case where the voltage is low.
- the invention also proposes a method for controlling a rotating electrical machine comprising a first element capable of generating a rotating magnetic field with respect to the first element and a second element provided with a winding able to be traversed by a current in order to that the rotating magnetic field causes the second rotating element, characterized by the following steps: measuring an electrical quantity at least related to said current; generation of the rotating magnetic field from a given instant as a function of the measured electrical quantity.
- the optional features of the electric machine presented above may apply in the same way to this method.
- FIG. 1 shows the circuit diagram of a reversible three-phase rotating electrical machine according to the teachings of the invention
- invention FIG. 2 represents the evolution of the current in the winding of the rotor of the machine of FIG. 1.
- the rotary electrical machine shown in FIG. 1 essentially comprises a mechanical assembly 2 formed in particular by a rotor and a stator and an electronic module 4 comprising a power circuit 14 and a control circuit 12.
- the electronic module 4 is powered , here directly, by the battery
- the electronic module 4 could be connected to the battery 16 via an electrical energy storage circuit, formed for example by a super-capacitor and a DC-DC converter.
- the electronic module 4 is powered by the super-capacitor which is connected to the battery via the DC-DC converter (the latter allowing correct operation despite a variable voltage, for example between 12 V and 25 V, at the level of the super-capacity of storage of electrical energy, and a relatively stable voltage at about 12 V, drums).
- the rotor of the mechanical assembly 2 carries a winding 6, while the stator associated with it carries three windings 10 able to generate a rotating magnetic field by successive injection into the different windings 10. a current by means of controlled switches of the power circuit 14.
- a position sensor 8 is also provided to indicate the position of the rotor to the control circuit 12 (connections D, E, F) to allow precise control by the latter controlled switches (by means of signals A, B, C and A ', B', C).
- the rotor (which carries the winding 6) is also coupled to the engine of the vehicle and the rotating electrical machine thus has at least one starter function, when the control circuit 12 causes the closing and opening of the appropriate controlled switches of the power circuit 14 so as to inject current from the battery 16 into the different windings 10 of the stator so as to drive the rotor, and consequently the motor, in rotation.
- the rotating electrical machine can also (but not necessarily) have an alternator function in which case, when the motor is rotating, the rotation of the rotor within the stator causes the generation of current through the power circuit 14 to the battery 16, which is thus reloaded. It is said that the rotating machine is reversible.
- the electronic module 4 further comprises a circuit 18 for measuring the current in the winding 6 of the rotor.
- the winding 6 of the rotor is connected to two terminals G, H of the control circuit 12 to the cable means, one of which carries the circuit 18 for measuring the current, the measured information being received by the control circuit 12 at a terminal I.
- the cable means one of which carries the circuit 18 for measuring the current, the measured information being received by the control circuit 12 at a terminal I.
- control circuit 12 begins the premagnetization phase by applying a voltage (for example the voltage of the battery) terminals G, H connected to the winding 6 of the rotor (t o in Figure 2).
- a voltage for example the voltage of the battery
- the voltage applied across the winding 6 could be for example the voltage across the super capacitance, which is therefore variable to a large extent.
- the voltage applied to the winding 6 can moreover also be variable, for example as a function of the charge of the battery 16 or other parameters that can affect the voltage, for example the state aging of the various components and the outside temperature.
- the control circuit 12 monitors, by means of the measuring circuit 18, the value of the current flowing through the winding 6 until this value reaches a predetermined threshold i s (for example of a value of 20 A).
- the control circuit 12 When a current of value i s is detected in the winding 6 by means of the measuring circuit 18 (time t 1 in FIG. 2, the duration t 1 - t 0 being variable as a function of the voltage used), the control circuit 12 causes the control signals A, B, C, A ', B', C to start up to the controlled switches of the power circuit 14 in order to initiate (i.e. to start) the generation of a rotating field by means of windings 10 of the stator.
- the pre-magnetization phase makes it possible to exactly reach the current value determined as optimal (so-called “saturation” current from which the electromotive force of the rotating machine no longer increases), whatever the external conditions, in particular of voltage, of the electronic circuit.
- the above example is only one possible embodiment of the invention, which is not limited thereto. It is possible in particular to replace the measurement of the current in the winding 6 by a measurement of the voltage applied to this winding, in which case the duration of the pre-magnetization phase is for example determined by the control circuit 12 as a function of the voltage measured, for example by means of a correspondence table (where LUT of the English "Look-Up Table") determined where appropriate based on prior tests.
