ОПТИМІЗАЦІЇ КВАЗІСТАЦІОНАРНИХ РЕЖИМІВ РОБОТИ СИНХРОННИХ РЕАКТИВНИХ ДВИГУНІВ З ПОСТІЙНИМИ МАГНІТАМИ ДЛЯ ЕЛЕКТРОБУСУ

Abstract. The work created an algorithm for determining the optimal control parameters of a traction synchronous jet motor with permanent magnets based on the specified power supply conditions and rotation frequency. The dependences of the drive efficiency, the traction motor efficiency, the load angle and the modulation coefficient for their optimal combination were analyzed. These dependences show similar trends for different temperatures of the stator winding, which reflects the consistent operating behavior of the traction system. It was determined that at a rotation frequency above 0.68 relative units and a torque above 0.6 relative units. A current limitation zone is observed, where the efficiency drops to zero both in the traction mode and in the braking mode.
