Whirl Magnetic Field Show Instrument of Three-Phase Asynchronous Motor

采用RC低频振荡器 ,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。

This paper illustrates that design method of whirl magnetic field instrument of three-phase asynchronous motor. This instrument lower frequency of three-phase alternating by apply RC-oscillator. The instrument can make a show of whirl magnetic field of three-phase asynchronous motor.
