YD2系列变极多速三相异步电动机

适用于：要求随负载的性质逐级调速的各种传动机械如机床、矿山、冶金、纺织、印染、化工等行业。
特点：采用改变绕组的接法来变换电机的转速和输出功率，使其与机械设备的负载特性相匹配,简化了变速系统，高效、节能。
变速方案：双速、三速、四速

Applications: widely used in such industry which have step changes of rotational speed to meet the requirements of load character, as m-achine tools, mining, metallurgy, textile, printing and dyeing, chemical industry and agricultural machinery, etc.

Features: simplify speed-changing systems by changing the connection to obtain diferent output and speed.Pole-changing mode: double, three or four speed.
