Claims

[Scope of utility model registration request]

A stator is formed by forming a large number of pole teeth at the same pitch on the top surface of a prismatic body made of magnetic material, and a plurality of teeth are formed on the bottom surface of each at the same pitch as the pitch of the pole teeth of the stator. The movable body is a box-shaped body made of magnetic material in which a plurality of magnetic poles are arranged so that the distance between each magnetic pole is maintained at a predetermined distance, and the lower end surface of this mover is connected to the upper end surface of the stator through a small gap. Wheels are attached to each of the four corners of the mover so that it can move along the stator while facing each other, and the mover moves step by step by sequentially energizing the windings wound around each magnetic pole in a fixed order. In a motor, a supporting cylindrical shaft that rotatably supports each wheel and a fixed cylindrical shaft whose center line is slightly eccentric with respect to the center line of this cylindrical shaft are eccentrically arranged at one end surface of each shaft. The other shaft end of the fixing cylindrical shaft is inserted into the respective shaft holes drilled in the four corner sides of the slider, and the wheel is rotated just before being fixed to the slider. By slightly rotating the freely supported cylindrical shaft in the clockwise or counterclockwise direction when viewed from the direction in which the shaft center extends, the height of the small gap can be finely adjusted separately at each of the four corners of the slider.
