三相异步电动机旋转磁场显示仪

Rotating magnetic field display instrument of three-phase asynchronous motor

采用 RC低频振荡器 ,通过降低交流电的频率 ,设计了三相异步电动机旋转磁场显示仪 ,实现了三相异步电动机旋转磁场的可视化.

Decreasing frequency of alternating current and using RC low-frequency oscillator, the rotating magnetic field display instrument of three-fhase asynchronous motor is designed, and the rotating field can be abserved directly.
