  • Method for controlling electric motors, corresponding circuit and computer program product
    Patent number: 11146205
    Abstract: A multi-phase electric motor includes a stator winding. The multi-phase electric motor is controlled by regulating a current flowing in the multi-phase electric motor in response to an applied voltage. An overload condition of the multi-phase electric motor is detected by monitoring a thermal increase of the value of a stator resistance of the stator winding of the multi-phase electric motor during a steady state condition of said multi-phase electric motor in which the current flowing in the motor has constant phase, and the motor is operating at constant load with constant speed.

  • Method of controlling electric motors, corresponding device and motor
    Patent number: 10476414
    Abstract: A driving circuit for an electric motor including multiple windings includes a sensing circuit to sense motor winding currents. A motor rotation angle signal is generated from the sensed currents and motor control voltages are generated as a function of the motor rotation angle signal. The motor windings are driven with motor drive voltages obtained by injecting into the motor control voltages injection pulses. The sensed currents include both torque components and injection components. The motor rotation angle signal is generated as a function of the injection components of the sensed currents.
