Latest Patents
Murry's latest patents include a "Method of recognizing signal mis-wiring of a three-phase circuit." This invention involves a signal analyzer that calculates the power consumption and power factor of a three-phase power system driving a motor. The analyzer determines whether its input terminals are wired correctly by observing patterns of zero crossing slope values of the three line-to-line voltages and the current in the power lines. It compares the slope of a voltage signal as it crosses zero volts with the corresponding current signal, allowing it to identify inverted signal wires.
Another significant patent is the "Method of controlling three-phase motor starting sequence." This motor starter comprises a motor and various contactors that control its operation. The transition auxiliary contactor manages the shorting contactor, while the shorting auxiliary controls the run contactor. This innovation enhances the efficiency and reliability of motor operations.
