Polyphase coils

Polyphase coils can be used to build polyphase generators. High voltage VFD motors are used in multiple electric vehicle lines. VFD motors require high voltage polyphase alternating current. We are currently using electronic switching from DC battery banks to drive these motors. That requires substantial battery storage and recharge needs.

 a better way:   a self charging system

   a battery flywheel generator (BFG).
