摘要
制造引起电机定子和转子相对偏心是客观存在的,因此研究不同极槽组合下偏心对转矩波动影响,对极槽组合设计有重要的参考意义。采用有限元仿真方法分析了分数槽集中绕组式无刷力矩电机不同极槽组合下静、动态偏心对转矩波动影响,并进行了样机试验,结果表明:宜优选绕组线圈分成多组对称均布且极槽数最小公倍数大的偶数槽组合。
The relative eccentricity of the stator and rotor of the motor caused by manufacturing is an objective existence. Therefore, studying the influence of eccentricity on torque fluctuation under different pole-slot numbers combination has important reference significance for motor design. The influence of static and dynamic eccentricity on torque fluctuation of brushless torque motor with fractional-slot concentrated winding under different pole-slot numbers combination was analyzed by finite element simulation method, and the prototype test was carried out. The results show that the even-numbered slot combination should be optimized, which the winding coils is divided into groups of uniformly distributed symmetry, and the lowest common multiple of the pole-slot number is large.
