Energy economizing ac power control system
Patent
·
OSTI ID:5420261
An induction motor has its stator winding energized from a sine wave power source through a signal-responsive wave modifier operative to control the portion of each cycle of the sine wave which is coupled from said source to the stator winding. The induction motor includes a squirrel cage rotor which carries an additional windings operative during rotation of the rotor to generate a polyphase ac voltage having an amplitude which is proportional to the load on the motor, and the ac voltage so generated is rectified to produce a dc signal which is coupled to a dc amplifier which in turn produces a control voltage for controlling the wave modifier.
