Latest Patents
Among his notable inventions is a synchronous motor system, characterized by a stepping motor equipped with toothed stator poles and two sets of oppositely magnetized rotor teeth. This unique design features a driver that responds to input pulses, enabling it to successively de-energize alternate poles while keeping them de-energized. The system then re-energizes the poles in the opposite direction, driving the rotor in fractional steps. For larger fractional increments, more poles are de-energized in response to each pulse, and for even greater fractions, the de-energization process is omitted altogether. This innovative approach to motor design enhances the efficiency and functionality of synchronous motors.
