    Possibilities of Permanent Magnet Synchronous Motor Efficiency Increasing using Flux Weakening Method

  • Original language description

    Permanent magnet synchronous motors (PMSM) due to their higher efficiency, small size, simple structure and many other advantages replace in many fields conventional induction motors and direct current (DC) motors. The flux weakening effect of PMSM for different speed values, up to nominal is described in this paper. Flux weakening is realized by increasing negative value of d-axis stator current component. By increasing this negative current value, iron losses are reduced, and copper losses are increased, but iron losses reduction prevails over copper losses increase. After description of theoretical analysis of PMSM and its structure the experimental results of torque and speed control were presented. The experiments were performed for different values of torque, speed and d-axis current component. Final results showed that the highest efficiency was mainly at highest values of torque and highest negative value of d-axis stator current component.
