  • Patent number: 7202620
    Abstract: A multi-phase unipolar motor is configured such that each stator pole is formed with bifilar wound primary and inductively associated secondary windings corresponding with one phase. The primary winding at one stator pole corresponding with one phase is coupled with a secondary winding at another stator pole corresponding with another phase to provide a commutational-step defined winding pair. The resultant winding pair assemblage is energized in correspondence with a commutational sequence such that collapsing field energy may be transferred from a primary winding at the termination of one step in the commutational sequence to the secondary winding associated with it in a next succeeding commutational step.
