摘要： An apparatus and method for inverting direct current electrical power into alternating current electrical power by producing a moving magnetic field having substantially constant flux density when the direct current power is applied to a primary winding, magnetically coupling a secondary winding to the moving magnetic field and creating a substantially triangular-shaped current in each phase of the primary winding so as to produce substantially sinusoidal alternating current in each phase of the secondary winding.

摘要： A circuit for providing dual speed operation of a single phase alternating current motor having high speed main and starting windings and a low speed main winding. A selectively energizable energizing circuit for the high speed main winding includes a current relay responsive to current flow through the high speed main winding for completing an energizing circuit for the high speed starting winding and a selectively energizable energizing circuit for the low speed main winding includes a bidirectional current translating device and a second current relay responsive to the flow of current through the low speed winding to complete the high speed main winding energizing circuit. The bidirectional current translating device is responsive to electrical control signals which are inhibited while the speed of the motor is greater than a predetermined value.
