Some typical winding schemes for far pole-ratio pole-changing machines are proposed in view of judging factor, and the analysis and experimental study of these schemes are shown.
These motors use starting winding. The motors possess medium starting torque, suitable for driving small tool machines, blowers, sewing machines and extraction fans, etc.
该系列电动机为电阻起动。具有中等的起动转矩，适用于小型机床、鼓风机、缝纫机、排气扇等机械。
