Title:
LINEAR PULSE MOTOR
Document Type and Number:
Japanese Patent JPS60229667
Kind Code:
A
Abstract:
PURPOSE:To improve the magnetic flux efficiency and to improve the response of a linear pulse motor by contacting a pair of poles with a permanent magnet, and providing an exciting coil for exciting the poles. CONSTITUTION:The surfaces of platelike poles 17-20 are polarized as pole surfaces, which are concentrically disposed, and a permanent magnet 33 is contacted with a pair of poles 17-20. The poles 17-20 are excited by exciting coils 27, 28. The relative positions of the teeth 17c-20c and the teeth 42a of a scale 42 are displaced by 1/4 pitch on the basis of the mutual action of the magnetic flux of the permanent magnet 33 and the magnetic fluxes generated by exciting coils 27, 28.
