A study on physical characteristics by temperature changes of electro-magnetic clutch installed in electric point machine

전기전철기용 전자클러치의 온도 변화에 따른 물리적 특성에 대한 연구

Electro-magnetic clutch which is affected by elements of electric, magnetic and mechanical friction is important that it has a characteristic changes by environmental impact. Expecially, it is equipped in railroad sideway which is bleak external environment. Therefore, this paper investigated affections by temperature changes, which can make out through physical characteristics such as friction torque, minimum slipping torque, rated slipping torque of electro-magnetic dutch.
