Title:
MOTOR, AND PUMP DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/150968
Kind Code:
A1
Abstract:
The purpose of the present invention is to hold a common wire such that the common wire does not protrude to the outer circumferential side of a stator. A motor 2 of a pump device 1 is provided with a resin sealing member 13 which covers a stator 11. The stator 11 is provided with a common wire 55A which connects conductor wires 55 led out from coils 53 of each phase. First common wire support parts 62 for supporting the common wire 55A from the outside in the radial direction are formed on insulators 52. The first common wire support parts 62 each have a shape which extends inward in the radial direction as the first common wire support parts extend towards the tip end side of the common wire 55A, and thus the common wire 55A can be inhibited from protruding to the outer circumferential side of the first common wire support parts 62. Accordingly, the common wire 55A can be inhibited from being exposed at the outer circumferential side of the stator 11.
