ABSTRACT:
A prime mover adapted for energization to a preselected speed therefor across a power source. The prime mover has a pair of winding means for excitation so as to effect the energization of the prime mover generally to the preselected speed when it is energized across the power source. Means is provided in circuit relation with one of the winding means and the power source for inhibiting the excitation of the one winding means generally as the prime mover attains its preselected speed, and means is operable generally in response to the occurrence of a preselected condition with respect to the excitation of the other of the winding means for placing the inhibiting means in open circuit relation with the power source generally as the prime mover attains its preselected speed.
A method of operating a prime mover, a method of interrupting the operation of means for inhibiting current flow therethrough, and a circuit are also disclosed.
