摘　　要：设计了一种旋转磁场发生装置,主要用于研究旋转磁场对农作物种子和幼苗的影响。本装置采用电生磁的原理,给对称三相绕组通以对称三相交流电产生旋转磁场。为满足后期研究需要,对三相交流电进行频率和幅值的控制,即可产生不同转速和不同强度的旋转磁场。In my paper,I conceived a generating device of rotating magnetic field which used to study the effects when rotating magnetic field act on organism.Mainly used for the effects on crop seeds and seedlings.According to the principle of electrophysiological magnetic,to electrify symmetrical three-phase winding with symmetrical three-phase alternating current to produce a rotating magnetic field.To meet the needs of the post-study,three-phase alternating current frequency and amplitude control to produce different speeds and the rotating magnetic fields of different intensity.
