An electrical rotating apparatus comprises an inverter system that outputs more than three phases. The apparatus further includes a stator electrically coupled to the inverter system, and a rotor electromagnetically coupled to a magnetic field generated by the stator. A signal generator generates a pulse modulated drive waveform signal, that has a frequency synchronized with the rotational frequency of the rotor, and the pulse modulated drive waveform signal drives the inverter system. The pulse modulated drive waveform signal has a pulsing frequency. Ad...
1. An electrical rotating apparatus comprising:a) a stator comprising a plurality of slots and windings; b) an inverter system for supplying an alternating current output having more than three phases to the windings; c) a rotor electromagnetically coupled to a magnetic field generated by said windings; and d) a signal generator generating a pulse modulated drive waveform signal having a pulsing frequency, wherein said pulse modulated drive waveform signal drives said inverter system, wherein a rotating magnetic field produced by said pulsing frequency r...
