Claims

[Scope of Claim for Utility Model Registration] 1. Left and right bearing covers connected to the motor case on the driving side, a field pole on the rotating side consisting of an annular magnetic pole iron core with an annular permanent magnet sandwiched therebetween;
A magnetic pole core on the rotating side for the rotation angle detector, a hollow shaft on the stationary side, and an armature on the stationary side consisting of a laminated iron core and a coil, which are provided facing the above-mentioned field pole connected to the hollow shaft across a gap. , a stator of the rotation angle detector consisting of a laminated core and a coil installed opposite the rotating side magnetic pole core of the rotation angle detector with an air gap therebetween, and a brake section disposed on the right side of the bearing cover. In the inductor type multi-polar AC motor, the above-mentioned rotating side field pole and the rotating side magnetic pole iron core for the rotation angle detector are attached to the inner circumference of the motor case with a through key, and the above-mentioned left and right bearing covers are attached. Apply the above to the rotating side field pole and the rotating side magnetic pole iron core of the rotation angle detector from the right and left sides, respectively, via O-rings, and tighten the tightening bolts between each bearing cover and the motor case. An inductor type multipolar AC motor characterized in that a rotating side is constructed by integrally connecting three parts. 2 Instead of the O-ring installed between the magnetic pole on the rotating side and the left bearing cover, a plug-shaped buffer made of a plurality of hard elastic materials is installed circularly on the right side of the left bearing cover. 2. The inductor type multipolar AC motor according to claim 1, wherein the inductor type multipolar AC motor is driven into holes drilled at appropriate intervals in the circumferential direction, leaving the heads intact.
