Abstract: The promotion of energy-efficient motor is a trend in the development of modern industry, with the improvement of motor efficiency requirements, the corresponding energy efficiency testing technology must continue to progress. Comparing with traditional analog or digital instrument manual detection methods of energy efficiency, GB/T 1032 test method to a series of type tests on the motor being tested to determine the efficiency of the loss and then the motor efficiency is calculated based on the application of the technology energy feedback energy-saving efficiency test system as a platform.
