Abstract: The work proposes a method for parameter estimation of induction motor and steady state performance for conventional as well as converter fed induction motor, based on equivalent circuit method. The method, which requires a no-load and a blocked rotor test, is intended for steady state performance i.e. torque, efficiency, full load current, output power, power factor of three-phase squirrel cage induction motor within the rated range of operation.Data of the tests (No load test, Block rotor test, Full load test ) taken from ERADA laboratory, and also simulate for conventional as well as converter fed induction motor using MATLAB-SIMULATION. Programming for estimation of parameter using numerical procedure Newton-Raphson method and determining steady state performance of induction motor algebraically and graphically (using circle diagram).
