YCT series electromagnetism speed regulating induction motor is A.Cconstant torque speed regulating electic machine which is controlled bysllicon controlled rectifier to get stepless speed regulating. YCT series motors are consisted of 3-phase induction motor,electromagnetism slip clutch, tachometer generator and electrical controllingunit. These motors can be used for all kinds-of the machine equipment, asspinning and weaving, film production, chemical industry, sprinting and dyeing,metallurgy, rubber, electric wire and so on. They are also suitable for centrifugal pump and blower fan load. 1. A.C stepless speed regulating, it has automatic regulating system,speed rated of variation is lower 3%, 2. Simple structure, easy in operation and maintenance, floor price. 3. Free of uncontroll point and wide range of speed regulating.4, Low power in controlling, easy selfcontrol, telecontrol.
