An integrated electric propulsion and ship service system is widely regarded as the best approach for achieving lower life cycle cost ships with reduced manning. The US Navy has selected Integrated Electric Drive for future surface combatants, i.e., DD-X and CG-X.
Choices for electric drive systems include the AC induction motor, the AC synchronous permanent magnet motor, the high temperature AC synchronous superconducting motor, and the superconducting DC homopolar motor. The superconducting DC homopolar motor is considered to be a conceptually superior alternative to the AC motors. Compelling advantages of the superconducting DC motor include:
* Significantly quieter, smaller, and lighter than AC motors
* 5% more efficient than the AC motor systems
* Control is more straightforward and simpler than the AC motor systems
* Suited to simpler and less costly ship electrical distribution architectures.
Was looking for something to do with my stash of magnets, and came across homopolar motors.
