Research of High-Speed Permanent Magnet Synchronous Machines Control

This paper presents the development of a research setup for high-speed permanent magnet synchronous machines. It describes the development of the hardware, the required components, controller and experimental results achieved. The setup was tested with permanent magnet motor up to 42000 min -1 , nominal torque 1,2 Nm and nominal current 11 A.  Results with two control algorithms are presented. It is the control of instantaneous current values and control in d-q frame. The two methods are compared with regard to calculation power requirements; results for two DSP systems used during development are shown.
