This paper explores dynamic behaviors of asynchronous motor under intermittent loading based on finite element models andsolutions in time domain. Transient Finite Element Analysis (FEA) of the motor in an on and off loading conditions is performed attime intervals of 0.2s for a 2D model. Dynamic characteristics such as speed, torque, phase currents and flux distributions of themotor were studied. It was observed that at the 37 Nm rated load, the motor recorded a negative speed when loaded intermittentlyat 0.2s intervals. The maximum load for which positive speed was observed is 32 Nm. The other characteristics were in acceptableranges for both loads.
