装置。 A rotation speed detector outputs a pulse signal corresponding to the rotation speed of the DC motor, and the output signal of this rotation speed detector detects whether the DC motor is in a normal rotation or a locked state, and when the DC motor is in the locked state, the DC motor is activated. A lock overheat prevention device for a DC motor, which includes a motor status detector that outputs an interrupt signal to stop the DC motor to a CPU that issues a drive command to the motor.
