を備えたＰＭ形ステツピングモータ。[Scope of claims for utility model registration] (1) N on the circumferential surface of a cup-shaped magnetic rotor.
A driving magnetic pole is formed by radially magnetizing S magnetic poles into 2P (P is an integer) pole with a fine pitch, a stator armature is provided opposite the driving magnetic pole, and one open end of the magnet rotor is provided. A magnetic encoder magnetic pole is formed on the inner surface of the closed end surface of the magnet rotor, with N and S magnetic poles alternately arranged at minute intervals along the circumferential direction and axially oriented and magnetized to 2P poles. A PM type stepping motor equipped with a position detection element in which a position detection magnetic sensor for detecting the magnetic pole is arranged opposite to the magnetic pole. (2) The magnetic encoder magnetic poles formed on the magnet rotor have the same magnetization pitch and the same polarity as the drive magnetic poles, and are attached from the inner surface of the magnet rotor facing the stator armature. A PM type stepping motor comprising a position sensing element as set forth in claim (1) of the utility model registration claim, which is formed by magnetization. (3) The above-mentioned magnetic encoder magnetic pole is a PM type equipped with a position sensing element according to claim (1) of the utility model registration claim, which is magnetized with a finer number of magnetized poles than the number of magnetized poles of the drive magnetic pole. stepping motor.
