ム。[Claims for Utility Model Registration] The motor has a feedback control section for the excitation current of the coil of the motor and a dynamic brake, and the dynamic brake takes two control modes depending on the rotational speed of the motor during braking. A certain motor control system includes a current detection circuit that detects the current flowing through the coil of the motor, and a speed detection circuit that detects the rotational speed of the motor based on the frequency of this detected current and applies the detected speed to the dynamic brake. A motor characterized in that the detection signal of the current detection circuit is shared as a feedback signal of the excitation current feedback control section and a signal for selecting a braking mode of the dynamic brake. control system.
