ABSTRACT:
A commutatorless direct current motor drive system that initiates rotation of a permanent magnet rotor from standstill upon the application of supply potential and then sustains rotor rotation by sequentially energizing the polyphase stator phase windings in response to the alternating current potential waveforms induced in the stator phase windings by the magnetic field of the permanent magnet rotor upon rotor rotation.
