ムにネジ止め接地した、 ことを特徴とするブラシレスモータ。[Scope of Claim for Utility Model Registration] A cylindrical stator made of laminated electrical steel plates, around which an armature winding to which an excitation current is applied is wound, is fitted and fixed to the shaft, and one end of the shaft is fitted and fixed to the housing. , A bearing is installed between the shaft and the two stepped inner surfaces of the spindle hub, which is made of a nearly bowl-shaped magnetic material, to support the spindle hub so that it can rotate freely around the shaft axis. A magnet is attached to the inner circumferential surface of the opposing spindle hub, a brush is attached to the other end of the shaft via a spring, and the brush is brought into contact with a protrusion provided at the center of the inner bottom of the spindle hub. A brushless motor characterized by being screwed to the device frame and grounded.
