Abstract

In this paper two operating modes available for permanent magnet synchronous machines (PMSM) are presented. This study aims to increase the efficiency of the motor-pump system. The PMSM is driven at variable speed and the inverter is controlled by space vector modulation theory. This study allows changing the component that produces magnetic flux (i_d), while the torque current component of PMSM (i_q) does not change. Reducing the magnetizing current will increase the stator winding flux linkages. The results show that for the same efficiency (when i_d is different to zero), the speed increases.
