| 摘要: |
| 为提高内置U型永磁同步电机电磁性能及抑制电机低频振动噪声,提出一种U一型磁极结构并结合Halbach充磁方式、转子开槽的电机拓扑。首先,推导电机相关电磁性能表达式,分析定转子间气隙径向磁通密度、径向电磁力密度的低频振动和噪声波动构成。其次,采用解析法与有限元法得到气隙径向电磁力时空分布,利用参数敏感度分析法、参数扫描法和响应面法对所选转子拓扑参数进行多目标优化并得到最优参数解。最后,将U一磁极结构空载反电动势、径向磁通密度、齿槽转矩、输出转矩、转矩脉动、径向电磁力密度、振动加速度和声压级与4种U型磁极结构进行对比分析；并结合电磁场、机械场和声场对U一型电机结构进行验证。结果表明,通过在U型磁极结构上增设一型磁极、改变充磁方式、dq轴开槽调制气隙磁场正弦度,使得电机齿槽转矩降低91.3%,空载反电动势提高53 V,输出转矩提高39.6%,气隙中径向电磁力波的各阶次谐波幅值均有所下降,各频率下定子总成振动加速度降低明显,电机周身声压级最大值处下降9 dB,下降率为10.1%。 |

| Abstract: |
| To improve the electromagnetic performance of the built-in U-type permanent magnet synchronous motor and suppress the low-frequency vibration and noise of the motor, a motor topology is proposed with a U-type pole structure combined with the Halbach magnetizing method and rotor slotting. Firstly, the relevant electromagnetic performance expressions of the motor are derived, and the low-frequency vibration and noise fluctuation composition of the radial magnetic flux density and radial electromagnetic force density between the stator and rotor are analyzed. Next, using analytical and finite element methods, the spatial and temporal distribution of the radial electromagnetic force in the air gap is obtained. Parameter sensitivity analysis, parameter scanning method, and response surface method are used to multi-objective optimization of the selected rotor topology parameters to obtain the optimal parameter solutions. Finally, no-load reaction potential, radial flux density, cogging torque, output torque, torque pulsation, radial electromagnetic force density, vibration acceleration and sound pressure level of the U-type pole structure are compared and analyzed with four other U-type pole structures. The U-type motor structure is validated by combining electromagnetic, mechanical and acoustic fields analyses. The results show that by adding a type I magnetic pole to the U-type magnetic pole structure, changing the magnetizing method, and modulating the sinusoidal degree of the air gap magnetic field by dq-axis slotting, the motor’s cogging torque decreased by 91.3%, the no-load reverse potential is increased by 53 V, the output torque is increased by 39.6%, the amplitude of radial electromagnetic force waves in the air gap decreased at all harmonic orders, the vibration acceleration of the stator assembly decreased significantly at all frequencies, and the maximum sound pressure level around the motor decreased by 9 dB at the peak, with a reduction rate of 10.1%. |
