A dc motor driving an ac alternator was used to simulate an asynchronous wind electric generator. The output was used to drive a commercial air conditioning unit containing a hermetically sealed three ...

These motors are a type called induction motors which, as a cost saving measure, have no permanent magnets and therefore can’t simply be used as a generator.

A new-generation direct-drive permanent magnet generator (PMG) concept that could clear the way for engineers to develop giant 25MW offshore wind turbines is on track to be market-ready by 2022, with ...
