Design and experiment of high speed motor test system

High speed motors have been widely used in many industrial areas, such as spindle system, compressors, flywheel energy storage and distributed generation etc. Now, motors are developed to higher speed and power. But the high speed motors test technology became a difficult problem because of rotor dynamics and machining tolerance. Therefore, this paper presented a novel test system to solve this problem that motors are loaded with high speed. Through the high speed motor test system, we can test the motor below the 40000rpm, 20kW. And the test system could supply the detailed running data for high speed motor design.
