变极多速三相异步电动机是三相异步电动机的主要派生系列之一,该系列电机可随负载状态有极的改变转速,达到功率的合理匹配和简化变速系统。Y2D系列电动机外形安装尺寸与JHM系列同中心高产品完全相同,便于安装和互换。 The Y2D series multispeed three phase asynchronous motor is one of the main derivative series of three phase asynchronous motor. The Y2D series motors can change its speed with load state by changing the connection to rational matching of power and simplify transmission system. The Y2D series motor has the same mounting dimensions with the JHM series.
