WGM Motors: Water Jacket Cooled

Developed to provide cooling through water flow on the end bells and around the frame allowing an increase on the horsepower / weight ratio and a decrease on the space usage.

The motor cooling is guaranteed by a “water jacket” circulating between the stator core and the outer frame, which allows a more effective heat exchange resulting in a higher power per weight ratio, therefore reducing the size of the motor. This system is ideal for variable speed applications since the thermal efficiency is optimized even on reduced speeds and where space is a concern.
