Abstract

The noise, vibration and harshness (NVH) performance of single-phase induction motor (SPIM) is often ignored, and the existing optimization methods of SPIM are difficult to achieve the improvement of output performance and NVH performance simultaneously. To solve this problem, a multi-objective optimization method considering both the geometric parameters and winding parameters of SPIM is proposed in this paper. Firstly, the key frequency components that contribute greatly to vibration and noise of SPIM are obtained through the vibration and noise measurement of the prototype. Then, the electromagnetic finite element model (FEM) of SPIM is established, and the geometric parameters of SPIM are optimized with the torque, efficiency and amplitudes of key frequency electromagnetic forces as the optimization objectives. After that, the analytical model of SPIM output performance is established, and the winding parameters are optimized with the torque and efficiency as the optimization objectives. Finally, the torques, efficiencies and amplitudes of key frequency electromagnetic forces of the SPIM before and after optimization are calculated by the electromagnetic FEM, and the optimization results are evaluated. The above process can be iterated until the optimization requirements is met. To verify the effectiveness of the proposed method, an SPIM with rated power of 800 W is taken as an example to illustrate the optimization process in detail. The output performance, vibration and noise of the SPIM before and after optimization are measured by dynamometer, vibration acceleration sensor and sound intensity sensor, respectively. After optimization, the torque and the efficiency of the motor are increased by about 4.9% and 0.5% respectively, and the vibration and noise are reduced by at least 76.6% and 4.6 dB (A) respectively.

考虑几何和绕组参数的单相感应电机多目标优化
单相感应电机(SPIM)的噪声、振动和声振粗糙度(NVH)性能往往被忽视,现有的 SPIM 优化方法难以同时实现输出性能和 NVH 性能的改善。为解决这一问题,本文提出了一种同时考虑 SPIM 几何参数和绕组参数的多目标优化方法。首先,通过对样机的振动和噪声测量,获得了对 SPIM 振动和噪声影响较大的关键频率成分。然后,建立了 SPIM 的电磁有限元模型(FEM),并以转矩、效率和关键频率电磁力的振幅为优化目标,对 SPIM 的几何参数进行了优化。随后,建立了 SPIM 输出性能的分析模型,并以扭矩和效率为优化目标对绕组参数进行了优化。最后,通过电磁有限元计算 SPIM 优化前后的扭矩、效率和关键频率电磁力的幅值,并对优化结果进行评估。上述过程可反复进行,直至达到优化要求。为了验证所提方法的有效性,我们以额定功率为 800 W 的 SPIM 为例,详细说明了优化过程。优化前后 SPIM 的输出性能、振动和噪声分别由测功机、振动加速度传感器和声强传感器测量。优化后,电机的扭矩和效率分别提高了约 4.9% 和 0.5%,振动和噪音分别降低了至少 76.6% 和 4.6 dB (A)。
