ABSTRACT:
An electric motor controller controls the currents flowing through the phase windings of an electric motor. The electric motor controller includes driving stages for driving respective phase windings of the motor and a memory for storing samples of reference signals. The driving stages force currents corresponding to the reference signals through a respective phase winding of the motor. The electric motor controller includes circuitry to determine subdivision degree intervals of an electric rotation and circuitry for comparing one of the currents flowing through the respective phase windings of the motor with at least one of the samples of the respective reference signal in at least one portion of each one of the degree intervals.
