Abstract

PURPOSE: To make an accurate phase difference, by providing spiral projections of different pitch on the inside surfaces of electromagnets and the outside surface of a shaft extending through them.
CONSTITUTION: The electromagnets A∼D are juxtaposed at a prescribed spacing. The shaft 10 extends through the electromagnets. A spiral projection of magnetic substance with a prescribed pitch is provided on the outside surface of the shaft 10. Spiral projections of pitch different from that of the former are provided on the inside surfaces of the electromagnets A∼D. The electromagnets are sequentially energized. The shaft 10 and the electromagnet assembly are displaced relatively to each other in the axial direction depending on the difference in the pitch.
