IPM 112B V400

Brushless synchronous motors

Energy efficiency, reliability and high performance in a single product.

The PM IE4 motor makes it possible to obtain a return on the initial investment after few months from its start-up, as electricity consumption decreases compared to an IE1 motor.
In addition to having these real economic savings, the use of IE4 motors increases the reliability and performance of the entire system.
