摘要： A motor driving apparatus for driving and braking a motor equipped with a brake comprises a motor/brake driving DC power supply which is used both as a motor driving power supply and as a brake driving power supply, wherein when the motor/brake driving DC power supply is being used as the motor driving power supply, a voltage conversion circuit via which a voltage supplied from the motor/brake driving DC power supply is applied to the brake feedback-controls the voltage applied to the brake. This configuration serves to reduce the loss (due to temperature rise) in the brake coil of the motor being driven to move a robot arm.
