Marelli Motori TEWC High Voltage motors

Totally Enclosed Water Cooled Motors (TEWC Motors) is a design of electric motors in a fully enclosed housing with an integrated water heat exchanger.

Marelli Motori electric motors The B4J and B5J series cover a power range of up to 4000 kW and an operating voltage of up to 6 kV, the housing provides protection of at least IP55/IP56.

Feature of operation: reduction of the mutual influence of the electric motor and the environment on each other, heavy duty operation, high cooling efficiency, reduction of weight and size parameters.
