AC motor WSR Series

synchronous400 VIP55

PRODUCT DETAIL Wonder WSR Series are easy to service and cost-efficient with low rotor power losses and improved bearing life. While having good efficiency at nominal load, its partial load efficiency is better than traditional induction motors, which is important in variable speed applications when full output is not required. There’s no windings on the rotor, WSR motors are able to run without rotor copper loss and rotor heating, which improves operational efficiency and security. Besides, without damping on the rotor, the motor can respond quickly. In comparison to PM motors, WSR Series feature lower cost, because no permanent magnet materials are adopted. And they are suitable for extreme environment, since there’s no need to worry about the situation that permanent magnet may vanish at high temperature. With general frame size, Wonder WSR Series can serve as ideal replacement of traditional motors when the efficiency can comply with IE4 or even better. The motors of which the output is 11kW and below adopt integrated design and are suitable for water pumps, fluid transmission machines, etc. Main Tech Specifications: Frame Size: 71-225mm Output Power: 0.55-45kW Max.
