Abstract

PURPOSE:To prevent the burn-out of a motor by arranging temperature detectors at the brush holder and the magnetic field coil of the DC motor and starting or stopping the fan motor in response to the temperature rise of the motor. CONSTITUTION:Temperature detectors 21, 22 are arranged at the brush holder 11 and the field coil 10 of the DC motor with a fan motor 40 built-in, the motor 40 is started or stopped in response to the temperature rise of the motor 24, and the motor 24 and the fan motor 40 are stopped when the motor 24 is excessively heated abnormally. Since the motor 40 is started or stopped in accordance with the state of the environmental temperature in this manner, the battery 29 is energy-saved, and since the field winding is protected by the temperature detectors 22 and the breaker 26, the reliability of the driving system is improved.
