| 摘 要： | 建立了基于Bertotti铁耗分离理论,全面考虑交变磁化条件和旋转磁化条件下的永磁无刷直流电动机的铁耗计算模型。通过结合时步有限元方法,精确计算出了一台30 kW、4极3相表贴式永磁无刷直流电动机在额定转速为8 000 r/min时的定子铁心损耗。相较于传统的铁耗计算经验公式,本模型提高了永磁无刷直流电动机铁耗计算的精度和准确度,对电机的优化设计具有指导意义,有较好的工程应用价值。 |

| Abstract: | The model of iron losses calculation in PM brushless DC motor was built based on Bertotti's iron-loss model and considering both alternating and rotating behavior of the magnetic field.The stator core losses are calculated by time-step FEM method for a 30 kW,4-pole,3-phase,surface mounted PM brushless DC motor when its rotating speed is 8 000 r/min.Compared with the conventional experience equation,the model is more accurature and precise.And it is valuable for the motor optimization design and engineering ... |
