Rotary or linear electrical machine with permanent magnets for variety of power applications uses transverse magnetic flux and has divided windings fed with three-phase AC

摘要

The electrical machine windings have several wire coils fed with three-phase AC derived from a DC source by a bridge-type inverter circuit. The exciter coils (a,b,c) are wound round multiple pole pieces. A current (i R) flows through the coils. The electromagnets are set at a given spacing (2tau 1) and there may be three magnets (tau) for each coil division.
