The present invention relates to a method for controlling a single-phase permanent magnet electric motor (M) movable through a power signal (SC) generated by an electronic control apparatus (100, 200, 300) of the motor based on a reference signal (S PWM ). The method comprises the steps of:
- generating, by a sensor unit (SEN, 40) associated with the motor (M), a first signal (S2) representative of the rotation speed of the motor (M);
- providing a protection block (500) of the motor against operation anomalies, which is included in the electronic control apparatus (100, 200, 300);
- providing a second signal (d) at a first input (1) of the protection block (500) of the motor, the second signal (d) being representative of duty-cycle values associated with the reference signal (S PWM );
- providing the first signal (S2) at a second input (2) of the protection block (500) of the motor;
- generating, by the protection block (500) of the motor, based on the first signal (S2) and the second signal (d), a third (C1) or a fourth (C2) signal following the detection of a first or a second operating condition of anomalous operation of the motor, respectively;
- disabling the generation of the power signal (SC) provided to the motor (M) by the electronic control apparatus (100, 200, 300) based on the third (C1) or fourth (C2) signal to stop the motor. |
