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.
