Abstract

PURPOSE:To reduce cogging force, by dividing, etc., the shape of tooth profile of either of the primary and secondary magnetic circuits arranged face to face into first and second parts so that the rectangular shape may be of the same area. CONSTITUTION:In a scale 23 of a linear pulse motor a sit 23-1 is formed in such a shape as the areal part of half the area of pole teeth 6a is shifted in the moving direction by 1/8 (e.g. 0.09mm) of the tooth pitch in the position where scale teeth 23a-23b are relatively shifted in 1/4 pitch phase in the moving direction at a constant pitch and as the adjacently facing area of an obliquely interesecting line section is equal to the area of an oblique line section. This scale 23 is stuck to the base and formed into the secondary magnetic circuit. Thus, in one pole tooth cogging force whose phase is shifted at 180 deg. is generated and the vibration in moving can be suppressed.
