    摘要: Methods and apparatus are provided for aligning a control reference axis with a magnetic north of a permanent magnet motor. The method includes the steps of injecting a predetermined stator current on an estimated reference axis of the permanent magnet motor and introducing predetermined error on the estimated reference axis. The method further includes the steps of determining if a speed of the permanent magnet motor is greater than a predetermined threshold speed and setting the control reference axis to 180° added to the estimated reference axis if the speed of the permanent magnet motor is greater than the predetermined threshold speed or setting the control reference axis to the estimated reference axis if the speed of the permanent magnet motor is less than or equal to the predetermined threshold speed.

    摘要: A rotor assembly is assembled by providing an elongated rectangular strip of material having a first edge and a second edge defining a width, cutting the elongated rectangular strip to form a first patterned strip having a first side corresponding to the first edge, winding the first patterned strip portion around the perimeter of the rotor core such that the first edge is adjacent to the perimeter and the patterned strip portion forms a continuous laminated ring structure. Two laminated ring structures can be cut from a single strip, thereby reducing waste material and forming a strong structure.
