Core Loss Calculation in Step Magnetic of High-Speed Motor Stator
According to the reduction for efficiency of high-speed permanent magnet brushless DC motor (High-speed PM BLDC motor) by core loss of stator in the design process, the accurate calculation for stator core loss is very important.2-D finite element method is used to analyze the alternating magnetic field and magnetic field of the stator core of which a rotational speed of 27000rpm high-speed BLDC motor. Harmonic analysis is used for the step magnetic field of high-speed BLDC motor, Based on the model of Bertotti iron loss calculation, superposition of various frequency loss will be calculated, the calculation accuracy was validate to increase.
