摘　　要：无轴承永磁同步电动机是将无轴承技术运用到永磁同步电动机上的新型无轴承电动机。本文阐述了永磁同步电动机无轴承技术的工作原理,设计和实现了该电动机基于 LF2407A 数字控制的硬件实验平台和软件系统。通过对整个无轴承永磁同步电动机系统的实验调试,成功实现了无轴承永磁同步电动机转轴的稳定悬浮。The bearingless permanent magnet synchronous motor is a new type bearingless motor to which the bearingless technique is applied. The rudimental principles and basic characteristics of the bearingless permanent magnet synchronous motor are presented. In the paper, an experimental platform of digital control system for real-time control is designed on double-DSP(TMS320LF2407A). And the design scheme of the software and hardware is also introduced in detail. The results from the experiments of a surface-mounted permanent magnet-type prototype machine demonstrated the good performance of the suspension.
