  • Position corrected commutation of brushless direct current motors
    Patent number: 11557990
    Abstract: Examples of methods and systems for compensating for the timing delay caused by the winding impedance of the motor coils and/or for non-ideal rotor magnet shapes and positions are disclosed. The example methods and systems may include generating a synthesized commutation signal compensating for non-ideal magnet shapes and positions (e.g., asymmetrical magnet positions) on a rotor and/or compensates for the timing delay caused by the winding impedance of the motor coils.
