ABSTRACT:
An apparatus for controlling the starting and stopping of an AC induction motor, the apparatus comprises a first and a second magnetic permeable portions having a plurality of legs wherein a magnetic control flux of the second magnetic has an opposite magnetic polarity to the magnetic control flux of the first magnetic permeable portion; anon-spacer separating the first and second magnetic permeable portions to prevent magnetic control flux cancellation between the first and second magnetic permeable portions; a first and second AC power phase windings; and a first and second group of DC excitation control windings.
