摘要： 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 base 72 that fix stators 52a and 52b by contacting stator bottom surfaces 74, two stator mounting members each provided on a side of a corresponding one of the stators 52a and 52b and each extending from the base 72 to a height substantially equal to that of a stator top surface 73, and two plate-like support members 81 fixedly connected to the stator top surfaces of the respective two stators 52a and 52b and to a base top surface 84.

摘要： In a linear motor, the stators and sliders are arranged to fill a predetermined relationship. In one configuration, two stators each include a plurality of stator blocks arranged in a moving direction of sliders so that projecting poles are maintained at predetermined intervals. Boundary surfaces are formed in adjacent stator blocks so as to be displaced relative to one another between the two opposite blocks by a distance Ld in the moving direction of the sliders. When a distance between end surface of the slider blocks is defined as L and the overall length of one stator block is defined as L0, the components are arranged such that Ld>L/3 and (L0−Ld)>L/3.

摘要： A linear motor having a more preferable braking function is realized with a low cost. A linear motor has a slider and a stator. A driving winding is wound around the slider. A plurality of permanent magnets forming magnetic poles which invert at a predetermined period are provided on a surface of the slider opposing the stator. Teeth are formed on the stator with a predetermined spacing therebetween. The stator extends to a region outside of an effective movable range, and a braking winding is wound around the teeth in the extended portion. When the slider moves into a region outside of the effective movable range, an induced voltage is generated in the braking winding and a current flows. A thrust in a direction opposite to the movement direction of the slider is generated by the current.

摘要： In a linear motor having permanent magnets placed on a slider, the slider has slider blocks disposed in such a manner that relative positions between front ends of the slider blocks in a slider moving direction and salient poles of two stators opposing the slider blocks is shifted by approximately 130 to 230 electrical degrees. Because the positions of the frond ends of the slider blocks in the slider moving direction relative to the stator salient poles of SIDE-A are shifted from those of SIDE-B by P/2 corresponding to 180 electrical degrees, thrust ripples occurring on SIDE-A and SIDE-B have a relationship such that they are displaced by P/2. As a result, the thrust ripples of SIDE-A and SIDE-B are canceled, thereby reducing a thrust ripple with P/3 periodicity.

摘要： A plurality of projections are provided abutted with an outer circumference of a columnar axis inserted to an inner circumference of a rotor. The projections are provided in the direction of a magnetic pole in the rotor. When the rotor is fixed to the columnar axis, the projection parts are fixed by “plunge-in” and the other rotor inner circumference parts have an uniform clearance to the columnar axis. The clearance is filled with an adhesive agent, thereby fixing the rotor to the columnar axis.
