摘要

大功率高速飞轮储能电机通常运行在真空环境，电机的转子涡流损耗高且散热困难，易出现温升过高的问题。针对此问题，本工作开展多相电机相数与转子涡流损耗关系研究，多相电机磁动势公式证明十二相电机可削弱5、7、11、13、17、19次低次谐波，利用有限元法在Maxwell仿真软件中建立三相、六相与十二相电机模型并分析其转子涡流损耗，证明十二相电机可大幅度降低转子涡流损耗。高速永磁电机通常采用磁钢外加护套的表贴式转子结构，对比基于合金钢和碳纤维两种护套材料电机方案的转子涡流损耗情况，依据对比结果及制造工艺选择合金钢转子护套方案，最后基于合金钢护套方案进行温度场仿真分析，证明基于此方案电机温升的合理性。

Abstract

High-power

high-speed flywheel energy storage motors typically operate in vacuum environments where rotor losses are high and heat dissipation challenging

thereby inducing excessive temperature elevations. To address this issue

this study investigated the relationship between motor-phase counts and rotor losses. Theoretical analysis of the magnetic potential of multiphase motors demonstrated that a twelve-phase configuration suppressed the 5th

7th

11th

13th

17th

and 19th low-order harmonics. Models of three-

six-

and twelve-phase motors were established

and their rotor losses were analyzed. Results demonstrate that a twelve-phase motor significantly reduced rotor losses. High-speed

permanent magnet motors typically adopt a surface-mounted rotor with magnetic steel and an outer sleeve. Furthermore

the rotor losses of motor schemes based on two sleeve materials (alloy steel and carbon fiber) were compared. Based on the comparison results and manufacturing processes

the alloy steel rotor-sleeve scheme was selected. Finally

a temperature-field simulation analysis was conducted under this design

confirming the rationality of the motor temperature rise and ultimately validating the viability of the proposed system.
