This paper analyzes induction motor starting and reversing performances for pump drive. For theoretical analysis mathematical program MATLAB Simulink is used. Mathematical model of induction motor was improved with algorithm which consists of torque-slip function. Consequently, the results of modeling are accurate. At the end of transition process load torque circumstances of rotor speed was observed. During research obtained comparison of theoretical and practical measurements. In practical experiments was tested induction motor with wound rotor 0.3kW.
