Abstract : generally , the grinding wheel is driven by a wire - wounda . c . asynchronous motor , which is connected with outside by the rotor rheostat . according to the working characteristic of grinding machine , to apply mechanical kramer system to control the machine and how to perform are described and analyzed . this control system is proved to be more simple , reliable and effective in saving energy 文摘:磨床上的砂轮一般采用绕线式交流异步电机驱动，其转子绕组通过滑环可以与外部电路连接.根据磨床的工作特性，选择从其转子侧引入控制变量来实现调速，采用机械串级调速系统对其进行控制，使其具有高效率和良好的调速性能.实践证明，采用该方法实现磨床控制，其系统结构简单，可靠性高，节能效果好
