ABSTRACT:
Windingless rotor, variable reluctance, field excited, eletromechanical machines that provide for a family of windingless rotor machines consisting of both line commutated, synchronous machines, and self-commutated or self-synchronous machines, in both rotary and linear format. The basic operational format of this group of machines is a combination of an interdependent working relationship between the geometric parameters of the stator and rotor poles, and specially contoured pole surfaces and tips, all working in a complementary relationship to provide magnetically workable, variable reluctance air gaps that are capable of controlling the alternating magnetic flux waveform to effect a viable and efficient energy conversion process at substantially the fundamental frequency component, which is also the synchronous frequency of operation of the machine.
