摘要:
 摘要:针对新型永磁转子偏转式三自由度电机复杂的结构和自转与偏转相结合的运动模式,从能
量的角度利用解析法对气隙处磁场分布情况进行分析,并对不同转子极数下谐波含量和磁场变化
进行计算比较。通过磁场的分析结果得出电机定、转子之间能量传递情况,反映出电机能量转换的
两个阶段。采用虚位移法计算电机中的磁能,进而得到不同极数下转矩随电机运动角度的变化曲
线,在此基拙上分析了对应的磁场谐波变化情况。通过对电机磁场、磁能和转矩的计算,分析了电
机的运动情况及性能表现,并将解析法与有限元法模型进行对比,验证了解析模型的正确性。
Abstract:
 Abstract:According to the complicated structure and combined spin-deflection motion mode of a novel 3
一DOF deflection type PM motor, the air gap magnetic field distribution of this motor was analyzed with
analytical method from the angle of energy conversion. The harmonic content and magnetic field changes
in different number of rotor poles were compared. In addition,the energy transfer situation between stator
and rotor was proposed through the magnetic field analysis reflecting the two phases of the motor’s energy
conversion. The magnetic energy was calculated by the virtual displacement method and the torque chan-
ges with respect to the angles of movement under conditions of different number of poles were derived.
Based on the results,the corresponding changes of harmonic content on magnetic field were analyzed.
Through the calculation of magnetic field,energy and torque,the motion and performance of this motor
was analyzed. The results of analytical and finite element models are compared to verify the correctness of
the analytical model.
