摘要
采用降频法,设计了三相异步电动机旋转磁场仪.使三相异步电动机旋转磁场能直接观察.
This paper illustrates that design method of whirl magneic field instrument of three-phase asynchronous motor by apply method in lower frequency of three-phase alternating. This instrument make a show of whirl magnetic field of three-phase asynchronous motor.
