CONTROL CIRCUIT OF AN ELECTRIC MOTOR

Abstract

The invention relates to a control circuit (100) for a motor (24) comprising a plurality of windings and an output shaft, this circuit comprising: means (221, 222, 223, 231, 232, 233, 52, 54, 55) for supplying power to each winding of the motor and a first loop (10) for controlling at least one current supplied to the motor windings; a second loop (20) for controlling the angular speed of the motor, the output of this loop forming an input to the loop (10) for controlling at least one current supplied to the motor windings; a third loop (30) for controlling the position of the output shaft, the output of this loop (30) forming an input to the loop (20) for controlling the angular speed of the motor.
