In this paper, we consider the simulation of a 5.1 kW synchronous electric motor with a two-link frequency converter with a control system that monitors the speed on the shaft in the PSIM simulation environment. IGBT M2TKI-50-12 manufactured by Elektrovypryamitel Saransk were selected for the load current. In this case, the load on the shaft abruptly changed from 1.25 to 2 of the nominal value. Presented are graphs of current, output power, motor speed and torque on the shaft.

Keywords: permanent magnet synchronous motor, PSIM, two-link frequency inverter, spasmodic load variation
