。[Scope of claim for utility model registration] (1) A stator armature is provided in two stages, upper and lower,
On the circumferential surface of a cup-shaped or cylindrical magnet rotor facing each of the stator armatures formed in the upper and lower stages, N and S magnetic poles are radially arranged at a fine pitch into 2P (P is a plurality of integers) poles. A magnetic sensor for position detection is arranged at a position of the stator armature facing the magnet rotor between the upper stator armature and the lower stator armature, and the magnetic sensor is arranged to detect the position. A recess is formed on the circumferential surface of the magnet rotor facing the magnetic sensor and between the upper and lower drive magnetic poles, and N and S magnetic poles are radially oriented in the recess and arranged alternately at minute intervals to form 2P poles. Form a magnetized magnetic encoder magnetic pole part,
A servo stepping motor equipped with a position detection element, with a position detection magnetic sensor facing the recess. (2) The magnetic encoder magnetic pole part formed on the magnet rotor is formed by magnetizing N and S magnetic poles with the same magnetization pitch and in the same phase position as the drive magnetic pole, the scope of the utility model registration claim. A servo stepping motor equipped with the position sensing element described in (1).
