This paper presents a dynamic induction motor(IM) model which incorporates all the power losses. Thepresented module is entirely built in Simulink to investigate theeffect of varying the applied voltage and frequency on IMefficiency for different load applications. The model includes thepower losses such as copper losses, core losses, stray load andmechanical. The accurate determination of induction motorefficiency depends on the estimation of all above mentionedpower losses which are modeled and presented in this paper. Theeffect of variation in applied voltage and frequency on inductionmotor efficiency is investigated at various load conditions and theresults are tabulated and evaluated accordingly. The obtainedresults show that the efficiency of the IM is significantly affectedby the voltage and frequency levels especially at low load.Therefore matching the right applied voltage and frequency tothe motor terminal based on the load condition will reduce themotor losses and hence increase its efficiency.
