ータ。[Scope of Claim for Utility Model Registration] (1) A driving device that has magnetic pole pieces in two stages, upper and lower, on its circumferential surface and is multi-pole magnetized in a radial orientation, facing a stator armature that has conductive wire wound inside. In a PM type stepping motor in which a magnet rotor having magnetic poles is rotatably provided, the magnetic pole pieces of the upper and lower stator armatures are formed in the same phase position, and the upper and lower stator armatures of the magnet rotor are arranged in the same phase. On the opposing circumferential surfaces of the upper and lower stages, the magnetic poles are shifted by half from each other to create two irregularities with minute pitches.
P (P is an integer of 1 or more) are formed, and either the N or S pole is magnetized in radial orientation on the unevenness of each of the upper and lower stages, and a large number of strong and weak magnetic poles are alternately spaced at small intervals. A PM type stepping motor in which the driving magnetic poles are formed by magnetization to substantially have a large number of N and S magnetic poles alternately spaced at small intervals. (2) The PM type stepping motor according to claim (1) of the utility model registration, characterized in that no unevenness is formed between the upper and lower driving magnetic poles.
