Abstract：Using bacterial foraging algorithm of optimized, a method to estimate efficiency of induction motor is presented. It relies on measuring the stator current, the stator voltage, stator resistance, the power input and the motor speed, without the need for no-load and locked-rotor test. Through a 5.5 kW induction motor test, the results and other industry better algorithms are compared, including the particle swarm optimization algorithm, immune algorithm, as well as the measured torque gauge method. The results show that the method can estimate the motor efficiency accurately, and is simple and low cost.
