Output DC voltage and power control of a flux strengthening IPM generator and a quick speed acceleration of a high speed SPM motor

Abstract

Interior Permanent Magnet (IPM) synchronous generators can achieve high-efficiency and wide voltage range with field strengthening and weakening. The purpose of this paper is to drive a high speed Surface Permanent Magnet (SPM) motor powered by the IPM generator with the field strengthening at a low rotational speed. The control systems of both the IPM generator and the high speed motor are proposed. The experimental results demonstrate the effectiveness of the control system.
