Definitions

  • Known synchronous machines may also have failures related to a short circuit between two phases. Such a failure interrupts or greatly degrades the operation of the synchronous machine and repair can not be avoided.
  • Another object of the present invention is to implement such a detection method with simple, reliable, few and economic.
  • the objects assigned to the invention are achieved by means of a method of detecting a phase-to-phase short circuit in a polyphase synchronous machine comprising a stator and a rotor, said machine being equipped with at least one angular position of the rotor, the stator comprising a coil intended to be supplied with current, the rotor comprising means for generating a magnetic induction being provided to move around the stator, the angular position sensor comprising at least two measurement sensors of the rotor; magnetic induction and at least one electronic unit, the induction measurement sensors, fixed, extending at an axial end of the rotor opposite and in the immediate vicinity of the axial edges of the means for generating a magnetic induction, characterized in that it consists of:
  • the method according to the invention has the remarkable advantage that it can detect via the rotor angular position sensor, a possible short-circuit between two phases of the synchronous machine. No additional detection system specific to the determination of a short-circuit between phases is therefore necessary in a synchronous machine in which the method according to the invention is implemented.
  • FIG. 3 is an illustration of an exemplary embodiment of a removable support for the angular position sensor in front view, intended to be inserted into a synchronous machine in which the method according to the invention is implemented. ;
  • FIG. 5 illustrates, using a block diagram, an example of a vector control system of a synchronous machine with permanent magnets and a sinusoidal electromotive force, in which the method according to the invention is implemented.
  • FIG. 1 illustrates an exemplary embodiment of a synchronous machine 1 comprising an angular position sensor mounted on a stator 2 illustrated schematically in FIG. 4.
  • FIG. 1 shows an end portion 2a, for example in the form of an integral flange. mechanically of the stator 2.
  • the end portion 2a overlaps at least partially and without contact an axial end 3a of the rotor 3.
  • An example of arrangement between the axial end 3a and the end portion 2a is shown in more detail in Figure 2.
  • the stator 2 comprises a not shown winding, intended to be supplied with polyphase current via a power electronics device also called converter or inverter.
  • the latter is advantageously supplied with voltage and current.
  • the axial end 3a of the cylinder 3b which does not have permanent magnets 4, advantageously has a slightly flared shape in a radial direction. Such a conformation thus makes it possible to limit the space requirement resulting from the fixing of the holding part 5.
  • a holding part 5 is advantageously fixed on the cylinder 3b at the end of each groove by means of a screw 5b, thus axially blocking all rows of permanent magnets 4.
  • the synchronous machine 1 in accordance with the invention also comprises an angular position sensor of the rotor 3.
  • the angular position sensor comprises, in particular, sensors for measuring the magnetic induction. 6.
  • the latter are designed to detect the variation of the axial magnetic field generated by the permanent magnets 4. This variation of the axial magnetic field is detected and converted into a voltage delivered by the magnetic induction measurement sensors 6.
  • the removable support 7 has for this purpose an axial support portion 7a and a support end portion 7b.
  • the support end portion 7b extends substantially transversely to the axial support portion 7a.
  • the sensors for measuring the magnetic induction 6 are arranged on an outer face 7c of the free end of the axial support portion 7a.
  • the removable support 7 comprises at least one electronic circuit of the electronic unit or part of an electronic circuit of said electronic unit.
  • Hall sensors measure the DC component of the magnetic field
  • magnetoresistance sensors exhibit operation based on the variation in the electrical resistance of a material as a function of the direction of the magnetic field. applied. These sensors are known as such and are therefore not described further.
  • the vector control system 13 comprises a control unit of the converter 14, current sensors 15, a voltage sensor 16 and the angular position sensor 1a of the synchronous machine 1.
  • the vector control system 13 receives, for example, the torque setpoint C.
  • the control unit of the converter 14 calculates the voltage vector to be applied to said converter 14 so that the synchronous machine 1 reaches the torque setpoint C.
  • the vector control system 13 in particular a synchronous machine 1 with permanent magnets 4 and sinusoidal electromotive force, is known per se and will therefore not be further described herein.
  • the synchronous machine 1 according to the invention has the remarkable advantage that it comprises an angular position sensor enabling it to make a direct measurement of the magnetic field produced by the permanent magnets 4 and consequently to know the evolution of said field Magnetic as a function of time. This makes it possible to detect a deterioration of the performance of the permanent magnets 4 and consequently the performance of the synchronous machine 1.
  • a third step i3) the calculated slope dB (t) / dt is compared with a threshold value Vs.
  • the alert signal S reconfigures the polyphase power supply of the synchronous machine 1.
  • the synchronous machine 1 with permanent magnets 4 and sinusoidal electromotive force advantageously constitutes a motor-wheel.
