The document provides information on performing no load and blocked rotor tests on induction motors to determine their equivalent circuit parameters. 1. No load and blocked rotor tests involve measuring voltage, current, power factor and resistance/reactance values at no load and locked rotor conditions. 2. The tests allow determining parameters like stator and rotor resistances and reactances which are used to develop an equivalent circuit model of the motor. 3. The equivalent circuit model enables analyzing the motor's performance characteristics like torque, efficiency and power factor under different operating conditions.
