OVERHEATING DETECTING DEVICE FOR USE IN MOTOR

摘要

PURPOSE: An overheating detecting device is provided to reduce a cost by sensing the overheating of a motor using a diode as a temperature detecting element. CONSTITUTION: A stator(21) is coupled with a power generating room and consists of a plurality of fixing disks(21b), and a rotator(22) is coupled with a driving shaft so as that a plurality of rotation disks(22b) are placed between fixing disks(21b). A diode(D1) is connected to the fixing disk(21b) of the stator(21) and senses a temperature of a motor owing to a heat generated when the rotator(22) is rotated in a high speed. An overheating detecting part(60) compares the sense result with a predetermined reference voltage in order to detect an overheating of the motor.
