Estimation of induction motor parameters by a genetic algorithm

Textbook equations are available to calculate the torque that AC motors can provide. Quite often, the procedures outlined in textbooks for the determination of motor parameters only apply to small AC motors that can be tested in a lab. This paper covers the application of genetic algorithms to use motor nameplate data along with rated values such as voltages, currents and torque data to determine unknown operating motor parameters for an AC induction motor. These parameters can be used with textbook equations to offer solutions to load requirements and capabilities.
