RE: [Electric Boats] Re: Water Cooled Electric Drive

 

Just to be clear, the Vetus electric drive motor is a brushless permanent magnet DC motor.

As a brushless drive with outer fixed coils, the heat is generated in, and easily conducted out of the shell with liquid cooling.

This would not be the case for a permanent magnet brush motor.
