The paper presents the simulation results of the close loop two-mass electromechanical system model with the speed and current feedbacks. Motor speed is controlled by a torque-generated stator current component while maintaining the flux-generated current component steady. The torque-generated current component is corrected to track it set point in the current controller using its own dedicated PI controller. Simulink model of vector controlled two-mass electromechanical system is elaborated. The motor model is developed in stationary reference frame. Simulations results at starting motor at no load and applying different load are analyzed. The change of speed reference of motor, running with different load, is considered.
