As shown in fig. 3 to 5, the stator 20 includes:
a stator core 21 having a core back 211 extending in a circumferential direction and a plurality of teeth 212 extending radially inward from the core back and arranged in the circumferential direction;
an insulator 22 covering at least a portion of the plurality of teeth 212; and

Fig. 6 is a schematic view of an example of a washer 30 of a motor of an embodiment of the present application, and fig. 7 is a plan view of the washer shown in fig. 6. In the present embodiment, as shown in fig. 6 and 7, the gasket 30 has the communication hole 31, and the communication hole 31 communicates the inner space P1 closer to the coil 23 than the gasket 30 and the outer space P2 farther from the coil 23 than the gasket 30, and the wire can pass through the communication hole 31 from the inner space P1 and extend toward the outer space P2. Therefore, the circuit board and the socket are not arranged in the shell of the motor, so that the space in the motor is saved, the motor is miniaturized, the manufacturing cost of the motor can be reduced, and the mass production is improved.
In some embodiments, as shown in fig. 6 and 7, the gasket 30 has a top surface portion 32 expanding in a direction crossing the central axis O (see fig. 1 and 2), and at least a portion of the top surface portion 32 is in axial contact with the lower surface of the upper housing 40, as shown in fig. 2. Thus, the gasket 30 can function to insulate the upper case 40 from the wire.
In some embodiments, as shown in fig. 6 and 7, the washer 30 has a projection 33 extending downward from a radially outer end portion of the top surface portion 32, and the communication hole 31 communicates the projection 33 in the radial direction. This can improve workability.
In some embodiments, as shown in fig. 2, the lower housing 50 has:
a bottom surface portion 51 disposed below the stator 20 and extending in a direction intersecting the center axis O; and
and a cylindrical portion 52 extending upward from a radially outer end of the bottom portion 51.
In the present embodiment, the cylindrical portion 52 is cylindrical, and the cylindrical portion 52 is in contact with the outer peripheral surface of the core back portion 211, and as shown in fig. 1, a recess 53 recessed downward is formed in the upper end portion of the cylindrical portion 52, and the protruding portion 33 is accommodated in the recess 53. Thereby, the circumferential position of the washer 30 can be positioned.
In some embodiments, as shown in fig. 2, the lower end of the insulator 22 is in axial contact with the upper surface of the bottom surface portion 51. Thereby, the stator 20 and the lower housing 50 can be axially positioned.
In some embodiments, a resin sleeve (not shown) extending from the gasket 30 toward the outer space P2 is accommodated in the communication hole 31, and the aforementioned lead wire is disposed in the sleeve. Thus, the wire can be insulated by the sleeve.
In some embodiments, the wire is disposed within the sleeve in a state not covered by other components. Therefore, the wires are gathered in one sleeve, and the mass production is improved.
In some embodiments, the wire is disposed within the sleeve in a state covered with another member. This further improves the insulation properties.
In some embodiments, the wires are connected to the circuit board at the outer space P2. Therefore, the circuit board and the socket are not arranged in the shell of the motor, and the mass production of the motor is improved.
In some embodiments, the circuit board is housed in a case disposed in the external space P2. Therefore, the circuit board can be protected by the shell.
In some embodiments, the housing may have a fixing portion capable of fixing with an electric device disposed in the external space. Thereby, the mounting of the motor to the electrical apparatus can be ensured. In the present application, the specific form of the fixing portion is not limited.
