Barie holds a notable patent titled "Method Of Rotating A Polyphase Motor At Less Than Rated Speed." This invention involves a polyphase AC induction motor connected to a power supply through a soft starter. The soft starter utilizes three sets of inverse parallel connected silicon controlled rectifiers, with each set corresponding to a specific phase. The invention allows for low-speed starting and operation of the motor through triggering circuits that control the phases of the triggering pulses in relation to the supply phases. The low motor speeds are achieved by a gating sequence that generates a low frequency waveform, which is less than the main supply frequency. This innovative approach enables the AC motor to operate smoothly at speeds below its rated capacity while developing net positive torque. Career Highlights Walter G.
