The present invention has been made with the object of obtaining a vibrating axial gap type electric motor that can be mass-produced at low cost without using a swivel plate for generating vibration by breaking the rotational balance of a child and using a vibrating body that rotates while vibrating. It is a thing.

A coreless flat armature having coreless armature coil groups at equal intervals in the circumferential direction is provided, and the coreless flat armature is rotatably supported face-to-face with the field magnet via a gap in the axial direction. In the axial air gap type electric motor, when the coreless flat armature rotates, one or more armature coils at predetermined locations of the coreless flat armature are deleted so that the coreless flat armature rotates eccentrically and vibrates. This can be achieved by providing a vibrating axial air gap type electric motor in which vibration is generated by breaking the rotational balance of the coreless armature.

Vibration type axial gap type electric motor 20 shown in FIGS. 1 and 2.
The difference between the vibration type axial air gap type electric motor 4 shown in FIGS. 14 to 16 is that the swivel plate 3 can be omitted mainly in the electric motor 20, and in the electric motor 20 of this structure, the swivel plate 3 can be omitted. Since it is not necessary to attach the rotary shaft 2 ′ to the upper side of the electric motor 20, it is possible to form the vibration type axial gap type (DC) electric motor 20 that is shorter in the axial direction by that amount, and the armature coil 12 Since there is no -3, the electric motor is reduced in that the coreless flat armature 21 which will be described later becomes lighter.

Here, the plastic 23 is preferably selected from a material having a lower specific gravity than the armature coils 12-1 and 12-2, and the eccentric metal weight 24 is the armature coil.
The use of a metal having a higher specific gravity than 12-1 and 12-2, such as tungsten, gives favorable results.

Since 12-2 is a copper material, it functions as an eccentric weight, and since it has an eccentric metal weight 24, when the motor 20 is driven, the coreless flat armature 21 rotates while being eccentric. In addition, since vibration is generated in the rotation direction, the pager 5 built in the electric motor 20 vibrates.

A coreless flat armature is provided which is arranged concentrically with respect to the center point of the electric motor such as a rotating shaft and has a coreless armature coil group at equal intervals in the circumferential direction, and the coreless flat armature is arranged in the axial direction with the field magnet. Vibration is generated by deleting one or more armature coils at a predetermined position of the coreless armature in the axial air gap type electric motor, which is face-to-face and rotatably supported by a gap, and disrupts the rotational balance of the coreless armature. Since it does not require a swivel plate, it can effectively function for signal transmission for the visually impaired, for vibrators, for pagers, etc. Not only can the plate be dispensed with, but in this case, if the rotary shaft for mounting the swivel plate does not project from the upper surface of the electric motor, the thickness of the electric motor can be reduced by the thickness of the swivel plate and the projecting rotary shaft. As compared with the vibration type axial air gap type electric motor which has been conventionally used for the pager, there is an advantage that the axial thickness can be reduced. Therefore, if it is used in the above device, there is an advantage that the device can be manufactured in a small size and at a low cost.
