Abstract
The present invention provides a magnetic attractive force-offsetting linear motor which prevents motor thrust from varying due to changes in the position on a stator, thus enabling improvement of the motor thrust and of the accuracy of the machine tool and the quality of a processed surface. A magnetic attractive force offsetting linear motor has a basethat fix statorsandby contacting stator bottom surfaces, two stator mounting members each provided on a side of a corresponding one of the statorsandand each extending from the baseto a height substantially equal to that of a stator top surface, and two plate-like support membersfixedly connected to the stator top surfaces of the respective two statorsandand to a base top surface
