Abstract:
A DC brushless motor system is disclosed. When a rotor of the DC brushless motor is close to an aligned position, there will be current spike in the coil and voltage spike in an input capacitor. By decreasing the peak current limit of the current in the coil when the rotor is close to the aligned position, the current spike and the voltage spike are reduced.
