无刷直流电动机，用在磨粉机上的，谁家比较好？---请教
<P>国内有哪些生产无刷直流电动机著名厂家？，扭矩要达到110NM，转速最好比较低，500r/min 就可以。</P><P>我查了好多生产无刷直流电机的，都是小扭矩，小功率的，我是用在磨粉机上的</P>

Re: 无刷直流电动机，用在磨粉机上的，谁家比较好？---请教
怎么没人理啊？急得想哭了，我找了一个星期了也没找到大扭矩大功率的。急啊Re: 无刷直流电动机，用在磨粉机上的，谁家比较好？---请教
我要中力矩高转速的大概3500-4000RPM的
功率在20W左右就可以了
楼主.110NM有没有打错?
那力量也太大了吧...
Re: 无刷直流电动机，用在磨粉机上的，谁家比较好？---请教
还有一个问题，无刷直流电动机可以用来精确定位吗？我用无刷直流电动机来控制磨粉机上的磨辊轧距调节，看的论文说用无刷直流电动机，但是今天打电话给卖电机的，人家说无法实现精确定位，只能用伺服电动机Re: 无刷直流电动机，用在磨粉机上的，谁家比较好？---请教
小CC 你好“扭矩要达到110NM，转速最好比较低，500r/min 就可以。”这个电机很大的。
把问题再介绍详细些好吗。你的磨粉机又是磨什么粉的机器？

扭矩这么大一定要通过减速机来达到，精确定位是做不到的。
