Description:
The WE4 series is an ultra‑high efficiency three‑phase asynchronous motor meeting IE4 (Super Premium Efficiency) class. With significantly lower losses than IE3 motors, the WE4 series helps reduce energy consumption and operating costs. The motors are built with robust cast‑iron frames, TEFC enclosure and Class F insulation, and are designed for continuous duty in demanding industrial applications.
