GB/T 21209-2007
AbolishedGuide for the design and performance of cage induction motors specifically designed for converter supply
变频器供电笼型感应电动机设计和性能导则
Application Summary AI generated
This standard provides guidelines for the design, performance, and testing of cage induction motors intended to be powered by variable-frequency converters. It is applied in industrial settings where motors must operate under non-sinusoidal voltage supplies, such as in adjustable-speed drive systems for pumps, fans, and conveyors. The standard ensures motor reliability and efficiency by addressing harmonic losses, insulation stress, and torque characteristics specific to converter-fed operation.
