   I think you have it backward. The motor speeds are the results of the
line frequency not vice versa.

  Telsa did a LOT more than invent a better electric motor. You should go
read up on him and his work sometime. It's fasinating. FWIW the "better"
electric motor was a LOT more than just better, it was revolutionary.
