Induction motors are the most commonly used motors in industrial motion control systems. The slip power recovery scheme (SPRS) provides speed control of slip ring induction motor (SRIM) below synchronous speed. The slip power recovery drives is used in very large-capacity pumps and fan drives, shipboards VSCF (variable-speed/constant-frequency) systems, variable-speed hydro pumps/generators etc. In this paper a comprehensive analysis of slip power recovery scheme is presented. Simulation of the scheme is carried out using MATLAB/SIMULINK environment and experimental set up is prepared in the laboratory for a 2 HP motor. The experimental and simulation results are analyzed
