IN-SITU INDUCTION-MOTOR EFFICIENCY DETERMINATION USING THE GENETIC ALGORITHM

Numerous methods exist for determining the efficiency of induction mot ors. Many of them require a no-load test, which is not possible for in -situ determination. The evaluation of motor efficiency based on the m otor's nameplate or manufacturer's data, on the other hand, in many ca ses cannot ensure a fair assessment of induction motors employed in th e plant. An extensive survey of techniques for efficiency measurement is given. A new method is proposed for in-situ induction motor efficie ncy determination, based on the genetic algorithm. Results are compare d with torque-gauge results.
