Abstract
PURPOSE: To let two drive coils travel at a fixed speed, by forming a sine wave by a magnetic field passing through gaps wherein N, S poles are alternately magnetized in the longitudinal direction of a magnet, and by mounting the drive coils to yokes oppositely installed to the magnet in fixed relationship.
CONSTITUTION: Spacers 11, 12 in synthetic resin are held between the both ends of long yokes 9, 10, a magnet 13 is disposed to the yoke 10 and a plurality of N, S poles are alternately magnetized at regular intervals in the longitudinal direction. The distribution of magnetic flux by the magnet is made to be a sine-wave-like shape. With the yoke 9, drive coils 17, 18 are each wound on two coil frames 15, 16, which are connected by means of a connecting rod 14 and can freely be slid. When the centers of the coils 17, 18 are severally located at a point a and a point b of a wave form of the distribution of magnetic flux, the coils are located at the positions of sinθ and cosθ, and an electrical angle θ=2πx/λ(λ=wavelength) to the center of the coil 17 and the distance x of a reference position c is obtained. When letting currents proportional to the output of Hall elements 19, 20 mounted to the center portions of the coils 17, 18 flow, the drive coils slide on the yokes by fixed force.
