[Abstract]:An energy balance equation between mechanical energy and magnetic energy of a 45 K W dual-disk asynchronous permanent magnet eddy current speed governor is established. Combined with virtual instrument technology, a comprehensive test platform for the performance test of a magnetic-force coupling speed governor is designed and built, focusing on the speed control characteristics of the permanent magnet eddy current speed governor. The results show that the relationship between the output speed of the load and the air gap distance is quadratic function under the condition of constant load, and the permanent magnet eddy current drive has different air gap under different load conditions. When the air gap distance is constant, the load size and the load output speed are approximately linear, and the mechanical characteristics are "soft"; when the permanent magnet eddy current drive motor output speed, load and air gap distance are constant, the temperature of the permanent magnet disc, the radiator and the central connecting bearing will fluctuate in a very small range at last, showing a very small fluctuation. The test and analysis results can provide guidance and reference for further study of the working condition and optimization design of magnetic coupling governor.
