摘要
A method and apparatus for assessing the efficiency of an in- service motor. The operating characteristics of the in-service motor are remotely measured. The operating characteristics are then applied to an equivalent circuit for electrical motors. Finally the equivalent circuit is evaluated to determine the performance characteristics of said in- service motor. Based upon the evaluation an individual is able to determine the rotor speed, power output, efficiency, and toque of the in- service motor. Additionally, an individual is able to confirm the calculations by comparing measured values with values obtained as a result of the motor equivalent circuit evaluation.
