摘要
介绍YBZS与YZD型变极双速笼型电动机的基本原理,分析在起重机上应用时高低速的起动转矩匹配,介绍两台电动机并联使用以及起升机构控制电路的设计,给出了双速笼型电动机在起重机上应用的电路图。
The basic principle of YBZS and YZD type variable poles, two-speed sqirrel motor is introduced. The matching of the starting torque at high and low speeds is analysed for use in a crane. The parallel use of two motors and the design of the control circuit of the lift mechanism are presented. Electric circuit of application of the twospeed squirrel motors to a crane is given.
