Several faulty conditions that can occur during operation of three phase asynchronous squirrel cage motor are analyzed in this paper. The steady-state model of the motor is derived for calculating motor parameters and operating characteristics like the efficiency, power factor, starting torque and current as well as maximal torque at over and under voltage conditions of power supply. The steady-state characteristics of efficiency, power factor, phase current, the starting and maximal torque and the starting current are plotted and adequate conclusions are derived with respect to the decreased efficiency at under and over voltage, increased starting and maximal torque at overvoltage conditions as well as the increased starting current and losses with the increase of the voltage. The motor’s
dynamic model is derived for analyzing the impact of voltage asymmetry and loss of one phase on transient characteristics of speed, current and torque. The voltage asymmetry causes unequal currents in motor phases, overheating, vibrations, and torque pulsations which can be observed from the obtained transient characteristics. The loss of one phase can cause failure of the motor starting under full load,
torque ripple in case of no-load acceleration, reduced speed, and motor overheating. The proposed motor models contributed to the better understanding of these faulty operating conditions and preventive measures that should be taken to avoid severe motor damage.
