Latest Patents

Masahiko Satou holds a patent for a control system for brushless DC motors. This patent describes a control method that involves sequentially applying a current to one phase for a prescribed time, temporarily stopping the current, and then reapplying it to the same phase. The method includes measuring the state of the rise of the current when it begins to flow to the phase. Based on this measurement, the position of one of the magnetic poles is detected, which helps determine whether to switch the current to the following phase. This innovative approach allows for constant speed control by reading information from a driven disk to determine speed and selectively applying different currents.
