Totally Enclosed Water to Air Cooled Motors (TEWAC Motors) – execution of electric motors in a fully enclosed housing with a built-in water-to-air heat exchanger
Low-voltage and high-voltage electric motors The Marelli Motori B4V series covers a power range of up to 10mW and an operating voltage of up to 6kV.
The engine is cooled due to the interaction of the internal air medium with the water heat exchanger.
Feature of operation: reducing the mutual influence of the electric motor and the environment on each other, heavy duty operation, high cooling efficiency.
