Abstract
PURPOSE: To attain a high resolution, by dividing the lead of a spiral projection by the resolution of a rotary step portion consisting of an outer cylinder and an intermediate rotor to enable a minute linear step.
CONSTITUTION: A spiral projection 10a is provided on a shaft 10 which is inserted into the cylindrical rotor of a rotary step motor which comprises plural phase cores 13 which are magnetized by pulses and the cylindrical rotor 11 which is rotated by the magnetization. A spiral projection 11a is provided on the inside of the rotor so that the spiral projection 11a twists in the same direction as the former 10a. A magnetic circuit is made of the cores, the rotor and both the spiral projections depending on the magnetization. At that time, the shaft 10 and the rotary step motor including the rotor are displaced relatively to each other in the axial direction by a quantity corresponding to the rotation of the rotor, by the attraction of both the projections facing each other through a small gap. The minute linear step is thus performed.
