  • Driving permanent magnet motor based on neutral point voltage
    Patent number: 10686392
    Abstract: The present disclosure is directed to a permanent magnet motor control method and system. A new structure configuration of a permanent magnet motor has a rotor with two or more permanent magnets attached thereon, a stator wound in a “Y” topology with three coils (windings) arranged at 120 degree among one another, and a neutral point of the wound stator wired in a manner that the voltage at the neutral point may be detected in substantially real time. The detected neutral point voltages are analyzed together with the associated vectors of the excitation current provided to the windings of the stator to determine a speed of the rotor. The determined speed of the rotor is used for vector control.
