Hereinafter, the PCB and plate mounting structure of the motor according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention is a rotary shaft (not shown) is installed in the core assembly coupling portion 11 is pressed or inserted fixed to the inner peripheral surface of the core assembly 20, as shown in Figure 1 in a motor such as a brushless motor or an abduction type motor (not shown) The present invention relates to a structure in which a PCB (Printed Circuit Board, 30) and a plate 40 are mounted on a bearing housing 10 which is installed to support a bearing (not shown) for freely rotating the support. In FIG. 1, a winding is wound around a plurality of cores formed radially with respect to the core assembly 20, but the present invention is not limited to the core assembly 20, but the PCB is mounted on the bearing housing 10. If it has a structure for mounting the 30 and the plate 40, all can be applied.

As shown in FIG. 2, the bearing housing 10 is provided with a core assembly coupling part 11 formed to extend upwardly so that the core assembly coupling part 11 is press-fitted or inserted into an inner circumferential surface of the core assembly 20. It is fixedly coupled to the core assembly 20, the lower portion is extended by a predetermined length to be coupled to the circular groove of the plate (40). The bearing housing 10 has at least one protruding rivet portion 12 formed on an upper surface thereof, that is, a surface coupled with the PCB 30, and a lower surface thereof, that is, coupled with the plate 40. At least one protruding rivet portion 13 is formed on the surface to fix the PCB 30 and the plate 40 to the bearing housing 10 by rivet bonding. In addition, the bearing housing 10 may form a gap maintaining part 14 having a predetermined thickness for maintaining an insulation gap between the PCB 30 and the plate 40 on a surface coupled with the plate 40. Can be. When the gap holder 14 is formed in the bearing housing 10, the protruding

rivet parts

12 and 13 may be formed on the top and bottom surfaces of the gap holder 14.
