YR series motor

YR series motor from 4kw-500kw, 2,4, 6, 8p, IP44,54 class F insulation YR series (IP44) motors are 3-phase asynchronous motors with a wound rotor for generaluses. They are the upgraded products of the latest design in China. Thegrade of power and measurements for installment are in line with I.E.C. internationalstandard. Their mutual relations are similar to those of Model DIN 42679of West Germany, by changing the rotor's circumscribed resistance, the seriesmotors can acquire good start function and adjusted speed in small scope. Theyare widely used in start moment which is larger than that for squirrel cage, thecapacity of the electrified wire netting that is not enough to start the squirrelcage rotor motor, long and frequent start and in connecting the electric shaftto drive synchronously. The series motors are sealed motors and the protection grade IP44 The rated frequency for the motors is 50Hz; while the rated voltage is 380-440v. The insulation is of Grade F and the operation of this motor is S1(continous running). Connection mode: (3KW.Y);Rotor Y. The series motors have a lot of advantages such as high efficiency, strong overloadingpower, low noise, small shock, reliable framework and beautiful outer casing. Especially the rotor parameter is united in China, so it's convenient for consumersto exchange or form a complete set. Those who once chose the series motorsof JRO2, JRO2L and CRO can use YR series (IP44) motors which are more suitableif exported singly or in the form of a complete set.
