ELECTRIC MACHINE

摘要

An electric machine has a primary mechanical output or input, a plurality of electric sub-machine rotors each having an output or input shaft, a plurality of electric sub-machine stator magnets proximate the rotors, a drive train connecting each of the output or input shafts of the plurality of electric sub-machine rotors to simultaneously drive, or be driven by, the primary output shaft. Each sub-machine is selectively engaged or disengage depending on machine power.

主权项

1. An electric machine comprising:
a primary mechanical output or input; a plurality of electric sub-machines configured to selectively drive, or be driven by, the primary mechanical output or input respectively; a controller configured to: monitor a parameter of the electric machine indicative of the power of the electric machine; and, engage or disengage one or more of the plurality of electric sub-machines dependent upon the monitored parameter, so as to increase the number of sub-machines simultaneously driving, or being driven by, the primary mechanical output or input respectively at higher electric machine powers.
