Abstract: A method for detecting variations of the torque of a DC motor particularly suited for detecting an accidentally block of the motor, comprises the operations of generating a first signal representing the current flowing in the motor, multiplying the first signal with a pre-established function producing a product signal, generating a comparison signal to correspond to the slope of the product signal and signaling a torque variation if the comparison signal surpasses a certain threshold.
The method is implemented by a control circuit for detecting a torque variation of an electric DC motor, comprising sensing means of the current flowing in the motor, generating a first signal, first circuit means for generating a product signal of the first signal by a pre-established function, second circuit means for generating a comparison signal to correspond to the slope of the product signal, a comparator of the comparison signal with a certain threshold, signaling a torque variation when the comparison signal surpasses the threshold.
