Claims

[Scope of Claim for Utility Model Registration] (1) A vertical cross-section cup-shaped body integrally formed with a plastic magnet so as to have a stopper on the outer periphery and a recess for positioning and attaching the stator yoke on the outer top surface. A stator is formed by forming a cup-shaped cap body, and magnetizing 2P (P is an integer of 1 or more) magnetic poles of N and S poles in the axial direction on the inner surface opposite to the external top surface of the cup-shaped cap body. A stator yoke alignment member is provided on the external top surface of the cup-shaped cap body, which forms driving magnetic poles, rotatably supports a disk-type coreless armature through an axial gap with the stator-driving magnetic poles. A disc-shaped stator yoke is fixed in the mounting recess, and a commutator made of commutator pieces is provided on the disc-type coreless armature, and the commutator is connected to the positive power supply side arranged on the fixed side. The brush and the brush connected to the negative power supply side arranged on the fixed side are brought into sliding contact with each other, and the brush is placed in sliding contact with the surface of the disc type coreless armature on the opposite side facing the stator driving magnetic poles through an axial gap. An axial gap type electric motor in which a stop portion of the outer periphery of the cup-shaped cap body is fixed to a fixed plate provided therein. (2) The axial gap type electric motor according to claim (1) of the utility model, wherein the stop portion of the cup-shaped cap body is a flange formed at an end of the cup-shaped cap body. (3) A bearing for rotatably supporting a rotating shaft is fixed to a substantially central portion of the cup-shaped cap body having a magnetic pole for driving the stator, as described in claim (1) of the utility model. axial gap type electric motor. (4) The axial gap type electric motor according to claim (3) of the utility model, wherein the disk-type armature is a disk-type coreless armature that does not include an iron core. (5) The disk-type coreless armature is provided with a group of air-core armature coils arranged at equal intervals so as not to overlap each other, as claimed in claim (4) of the utility model.
The axial gap type electric motor described in . (6) Utility model claims (1) to (5), wherein a disk-shaped rotor yoke is provided on the opposite surface of the disk-type coreless armature that faces the stator driving magnetic poles. The axial gap type electric motor according to any one of the above.
