Latest Patents

Yamamoto holds a patent for a "Method of and apparatus for controlling single-phase induction motor, and electric chain block." This invention aims to provide a control method and apparatus that can accurately judge an overload condition of a single-phase induction motor, even when the auxiliary coil is repeatedly energized. The system includes a main coil, an auxiliary coil, a capacitor, and a solid-state relay power circuit. The main coil receives electric current from a single-phase alternating-current power supply, and the auxiliary coil is energized when the load is heavy. The overload is determined based on the ratio of energizing time of the auxiliary coil within a specified timeframe. This innovation enhances the reliability and efficiency of single-phase induction motors.
