Abstract
An efficiency-maximization motor controller that includes a use method has power conveyance to an induction motor ( ) with a digital signal processor (DSP) ( ) that calculates and optimizes supply of current for existent motor loading from a power supply ( ) and mains voltage through a control element ( ). The control element can include a standard triac, a field-effect transistor, an insulated gate bipolar transistor, a 3 quadrant triac or other select control element. Digital calculation and motor-control feedback of current requirements for motor loading and other motor parameters are calculated in millionths of seconds to provide motor-current optimization for all motor-use conditions. Calculation of motor-load requirement for current and supply of that current are effectively simultaneous.
