磁悬浮轴承(MBs)作为飞轮系统的重要组成部分,工作在真空环境,然而散热条件差,温度过高严重影响了飞轮的运行,降低了飞轮的可靠性。在对飞轮储能用混合型磁悬浮轴承损耗进行分析的基础上,利用ANSYS有限元软件建立混合型磁轴承的3D热模型,将不同运行状态下磁悬浮轴承的损耗作为热源导入温度场中,得到了磁悬浮轴承在不同运行状态下的温度分布,为磁悬浮轴承的设计和温升控制提供了重要的依据。

As an important part of the flywheel system, magnetic bearings (MBs) worked in a vacuum environment with poor heat dissipation and high temperature, which would seriously affect the operation and reliability of the flywheel system. The loss of hybrid magnetic bearing (HMB) for flywheel energy storage was analyzed. Based on this, the 3D thermal model of HMB was established by using ANSYS finite element software. The losses of the MBs under different operating conditions were introduced into the temperature field as heat source. The temperature distribution of the MBs under different operating conditions was obtained, which provided an important basis for the design and temperature rise control of the MBs.
