Abstract

The paper presents the design and implementation of a DSP-based controller for super high-speed (up to 200,000 rpm) permanent magnet synchronous motor (PMSM). Constant V/f control and space vector pulse width modulation (SVPWM) are realized by DSP software. The open-loop control scheme is employed because of its simplicity and advantage to high speed. When we design the V/f control for the super high-speed motor, due to the extra small size requirement of the proposed super high speed PMSM, stator resistance cannot be neglected anymore. An optimal design approach to the V/f control curve with consideration of the stator resistance is developed. Experimental results are presented and validate the effectiveness of the DSP-based controller at super high-speed.
