Magnetic Property Evaluation of the High-Speed Motor Stator Core Under Sinusoidal and Pulse Width Modulation Wave Excitation Using the Stator Winding Excitation Method
Abstract:Development of a small, high-speed and high-power motor is necessary to improve the performance of machines such as robots, and drones. The motor is excited by a high frequency voltage when the motor rotates high-speed. Moreover, the motor is driven by the pulse width modulation (PWM) inverter because efficiency and controllability is good. The driving voltage of the PWM inverter contains many higher harmonics waves. In such a motor, generation of heat due to the loss is a major problem. The loss of the motor … Show more
