Popis: Studying the dynamic performance is very important for improving the performance of the electrical machines. The sudden applied or removal the load is very critical for the electrical machines. It may lead to some problems in it's as, mechanical stress, surge current, increase the losses and decrease the motor life time. So, this paper studied this problem and constructed proposal model to reduce the effect of this problem on the electrical machines. This occurred through comparing between the effect of the dynamic load, sudden applied and removal loads on the performance characteristics of interior permanent synchronous motor (IPMSM) with proposal model and with classical model in the constant flux region and in the field weakening region. The simulation is done through the MATLAB program. The simulation shows the effectiveness of the proposal model on the performance characteristics of the IPMSM. With proposal model, the overshooting and under shooting of the motor speed are reduced. Rise time and settling time are improved, the response of the motor torque for load variations is improved and the stator currents are decreased. In this model, the space vector pulse width modulation is used to controlling the inverter which used to drive the IPMSM.
