Electric magnet velocity-adjusting electromotor has many characteristics of simple structure, convenient operation and reliable working, which is widely used in the conditions of permanent torque stepless velocity-adjusting especially degressive torque loading mechanics such as wind machine and water pump. If electric magnet velocity-adjusting electromotor is in natural function (i.e. exporting function of electric magnet velocity-adjusting electromotor when control system is in opening) or change its control ways ( for example instead of velocity feedback information with intention control signal), it can be used in intention control system. 　　　 YCT series electric magnet velocity-adjusting electromotor           　　The power grade and installment size of YCT series electric magnet velocity-adjusting electromotor should be consistent with IEC Standard . it consists of three-phase asynchronies electromotor, electric magnet rotation difference clutch and velocity-testing generator. It is usually matched with JD or ZTK control appliance to become one set of alternating currency stepless velocity-adjusting appliance. It is widely used in textile, film production, chemical industry, printing, dying, chemical fiber, metallurgy, paper-making, concrete, rubber, electric line, honey-making, medicine-making, plastic, power plant, food and silk as well as the energy-saving and velocity-adjusting of wind machine and water pump.
