    摘要: A method for magnetizing a rotor of an electrical machine is provided. The method includes assembling an array of non-magnetized anisotropic permanent magnet segments around a rotor spindle encased in a metallic ring. The method also includes determining multiple optimal magnetization orientation directions of the non-magnetized anisotropic permanent magnet segments. Further, the method includes positioning the assembled non-magnetized anisotropic permanent magnet segments around the rotor spindle such that the optimal magnetization orientation directions of the anisotropic permanent magnet segments are aligned with multiple flux lines produced by a magnetization fixture. Finally, the method includes energizing the magnetization fixture for magnetizing the segments via a pulse direct current for an optimal duration of the pulse.

    摘要: A motor control for a clothes washing machine having an electronically commutated motor (ECM). A position-feedback is employed by the ECM to control sinusoidal motion of the washing machine agitator. An agitator position feedback signal is constructed from the motor commutation signals, and is compared to a digitally created sinewave position command signal. The error between the two signals is fed to control system Proportional-integral (PI) block, and the output of the PI block sets the level of motor current command. The control system is implemented in a digital signal processor, which also controls the motor's electronic inverter.

    摘要: A system for preventing objectionable large torque pulsations during the starting and synchronization of a line-start permanent magnet motor compares motor speed with motor synchronous speed and power source phase with the motor back-emf phasor. The motor starting armature is coupled to the power source and the PM armature is disconnected from the power source before motor speed has reached to within a predetermined margin of synchronous speed and before the back-emf phasor has dropped below a predetermined phase difference. After motor speed has approached synchronous speed to within the margin and the phase difference has dropped below the predetermined phase difference, connections are reversed so that the starting armature is disconnected from the power source and the PM armature is coupled to the power source.
