摘要:

针对电动机采用深槽转子后起动性能仍未能达到要求的问题,为最大化深槽电动机起动性能方面的优势,提出了将发卡绕组用于深槽电动机的设想。首先分析影响电动机起动性能的所有参数,再结合发卡电动机和深槽电动机的相同点排除部分参数,最终发卡绕组能确定提升起动性能的理论重点为定子槽漏抗和端部漏抗。采用有限元仿真对比的方法,首先设计一台低压大电流的深槽电动机,再根据发卡绕组的特点,在仿真设计中改变深槽电动机定子绕组形式和缩短端部长度,以此来模拟发卡绕组,然后运用软件ANSYS对两电动机进行基本性能和瞬态性能的有限元分析,最后对比仿真结果验证了之前的理论分析。

Abstract:

Aiming at the problem that the starting performance of the deep slot rotor is still not met the requirement, in order to maximize the advantages of the starting performance of the deep-slot motor, the idea of using the hairpin winding to the deep-slot motor is proposed. Firstly, all parameters affecting the starting performance of the motor are analyzed, and then some parameters are excluded from the same point of the card issuing motor and the deep slot motor. Finally, the theoretical emphases of stator slot leakage reactance and end leakage reactance are determined to improve the starting performance of the card winding. By using finite element simulation comparison method, a low-voltage and large-current deep-slot motor is designed, and then according to the characteristics of the hairpin winding, the stator winding form of the deep slot motor is changed in the simulation design, and the end length is shortened to simulate the hairpin winding. Then, the software ANSYS is used to analyze the basic and transient performance of the two motors. Finally, the simulation results are compared to verify the previous theoretical analysis.

Key words: Hairpin winding, deep-slot motor, starting torque multiple
