一种新型线性电机及其在直线运动系统中的应用

针对传统直线运动系统在某些场合下存在体积大、安装调试难度高、系统动态性不好的问题,提出了用一种新型线性电机控制直线运动的方法。该电机的特点是电机轴中空,丝杠可以直接穿过电机轴,在该电机控制的直线运动系统中,丝杠一般不动,电机在丝杠上平动,从而使运动系统具有安装调试方便、体积小、动态响应特性好等特点。

A new kind of linear motor and its usage in linear movement system

In some case, traditional linear movement system is of huge bulk, unconvenient fixing, lowdynamic response, so we work out a new method of linear movement controlled by a newkind of linear motor. The main character of the motor is that it has a hollow axis throughwhich a screw can thread. In the movement system controlled by the motor, the screw isusually fixed, and the motor could move straight on the screw. The system has the advan-tage of convenient fixing, small bulk, and high dynamic response.
