Space saving water-cooled motors

The frame size of WEGs ultra compact water-cooled motors are up to two times smaller than standard water-cooled motors. WEG claim that the UTTW and USTW series motors deliver 1.5 to 2.6 times the power density of conventional water-cooled motors.


The AKH designed motors are energy efficient, reaching efficiency levels up to IE5, enabling users to optimise their processes and they ensure smooth running and low noise levels, which is vital for users working in confined spaces.

The induction motors in the UTTW series cover the power range from 24 to 240kW with a shaft height of 112 to 180mm, while the UTTW(p) series of - equipped with a water-cooled rotor - covers the range up to 300kW with the same shaft heights. The water-cooled synchronous motors in the USTW series feature the same compact design and are available with rated power of up to 440kW.
