摘 要: Active magnetic bearings (AMBs) represent an innovative contact free suspension technology with many advantages such as online adaptability of bearing stiffness and damping which makes AMBs especially suited for high speed rotor applications. Disadvantageous is the rather high system complexity which leads to a reduced overall reliability. To enhance AMB's reliability a new AMB concept has been developed using independently working hot-swap controller amplifier modules (HCA) for bearing control. Within this work the HCA electronic and the developed fault diagnosis is described which allows a complete functional test of all components during system operation as well as a safe deactivation of the HCA even in case of a component fault. Measurement results demonstrate the functionality of the developed HCA prototype.

主动磁悬浮轴承(AMB)是一种创新的无接触悬挂技术,具有诸多优势,例如轴承刚度和阻尼可在线调节,因此特别适用于高速转子应用。然而,其缺点是系统复杂性较高,导致整体可靠性降低。为提高AMB的可靠性,开发了一种新型AMB概念,采用独立工作的热插拔控制器放大器模块(HCA)实现轴承控制。本研究介绍了HCA电子模块及所开发的故障诊断技术,该技术可在系统运行期间对所有组件进行完整的功能测试,并在发生部件故障时仍能安全地停用HCA。测量结果表明,所开发的HCA原型具备良好的功能性能。
