单双层低谐波绕组感应电机振动噪声分析
|
摘要
分析了单双层低谐波绕组感应电机振动与噪声并探讨不同定子绕组形式对其产生的影响,对于额定功率为22kW,极数为2的小型感应电机Y180M-2中的电磁激振力情况进行了详细分析。先通过解析法分析单双层低谐波绕组的谐波磁势,研究由于线圈的分布不同带来电角度差对于谐波磁势产生的影响,包括线圈与每相绕组轴线的空间电角度差,以及线圈电流与电流轴线的时间电角度差;并探讨电磁激振力与谐波磁势的关系。最后利用2维有限元分析法仿真两台参数相同、但配置不同类型绕组的电机模型,对比验证得出在空载情况下,单双层低谐波绕组与普通双层短距绕组相比,降低了振动噪声,与解析法结果一致。
To analyze the vibration and noise of induction motors equipped with single-double layer low harmonic winding and discuss the influence produced by different winding type of stator. A detail analysis about the electromagnetic force of a 22 kW rated power,2 poles small size induction Y180 M-2 was given in this paper. Analysis method was applied to analyze the harmonic magnetomotive force(MMF) of a single-double layer low harmonic winding in the front. Thus to explore the influence on MMF that was brought by the distribution of the coil. The different distribution would bring respective electrical degree not only between the coil and the axis of the winding per phase in the space but also the coil current and the axis of the current in the time. The relationship between electromagnetic and MMF was also been studied by analysis method. Finite Element Analysis method(FEM) was also been used in this paper to verify the results inferenced by analysis method. 2 D FEM model equipped with the same prototype induction machine and different kinds of winding types were built to simulate the MMF and electromagnetic force of the motors. The results of FEM match that of analysis method,which means the single-double layer low harmonic winding can reduce the vibration and noise of induction motor under the no load circumstance.
