초록

This paper presents a microprocesser based Self-Controller for a Permanent Magnet Synchronous Motor(PMSM), fed by voltage soure inverter. The proper operation of the PMSM can be ensured only if the stator current is always synchronized with the its Back-E.M.F. The use of incremantal encoder with high resolution makes it possible to design a Self-Control led P.W.M. inverter. The pulse ratios are controlled to reduce the torque ripple in the low-speed drive region. And during the operation, torque - speed characteristics are improved by the control of optimal load angle.
