Design Concept of Vernier Motor Based on High Power Factor
为解决游标电机功率因数偏低的问题,提出了一种提高功率因数的电机设计优化思路.首先,使用绕组函数法计算出分数槽集中双层绕组的电感,推导出游标电机的功率因数表达式,分析影响功率因数的主要设计参数;其次,结合有限元法研究各设计参数改变时电机性能的变化规律,进而总结出设计思路;然后,以一台裂齿式游标电机为基准样机,按照所提思路重新设计一台高功率因数的电机,并采用遗传算法对电机主要设计参数进行多目标优化;最后,与基准样机进行性能对比,结果表明所设计电机的功率因数更高,验证了理论分析和所提设计思路的有效性.
In order to solve the problem of low power factor of vernier motor,a motor design optimization concept to improve the power factor is proposed.Firstly,the winding function approach is used to calculate the inductance of fractional slot centralized double-layer windings,to derive the expression for the power factor of the vernier motor,and to analyze the main design parameters affecting the power factor.Secondly,combined with the finite element method to study the change rule of motor performance when each design parameter is changed,and then summarize the design concept.Then,a cleft tooth vernier motor is taken as the benchmark prototype,a motor with high power factor is redesigned according to the proposed concept,and a genetic algorithm is used for multi-objective optimization of the main design parameters of the motor.Finally,the performance comparison with the benchmark prototype motor shows that the power factor of the designed motor is higher,which verifies the validity of the theoretical analysis and the proposed design concept.
