Motor

1. A motor, comprising:

a rotor including a shaft centered on a vertically extending center axis;

a stator radially opposite to the rotor and including a plurality of coils;

a bearing supporting the shaft;

a bus bar assembly on an upper side of the stator in an axial direction; and

a housing surrounding and fixing the stator; wherein

the bus bar assembly includes a bus bar holder holding a plurality of bus bars;

the stator includes a terminal portion connected to a lead wire drawn out from one of the plurality of coils;

the terminal portion includes a slit which extends axially and into which the lead wire is fitted; and

a width of the slit is narrower than a diameter of the lead wire;

the bus bar holder includes a protrusion protruding radially outside;

the housing includes a recess portion recessed radially outward or a radially penetrating hole portion or notch portion; and

at least a portion of the protrusion is fitted into the recess portion, the hole portion, or the notch portion.

2. The motor according to claim 1 , wherein

the housing includes a flange extending radially outward; and

a lower surface of the protrusion is in contact with an upper surface of the flange.

3. The motor according to claim 1 , wherein

the stator includes an annular stator core; and

the bus bar holder is in contact with an upper surface of the stator core.

4. The motor according to claim 3 , wherein

the housing includes a flange extending radially outward; and

the flange includes:

an extending portion extending in an axial direction on an outer circumference; and

a claw portion protruding radially inward from the extending portion and being in contact with an upper surface of the protrusion.

5. The motor according to claim 4 , wherein

the flange includes a pair of the extending portions provided at intervals in a circumferential direction;

the housing includes the notch portion; and

the notch portion is a gap between the pair of extending portions.

6. The motor according to claim 1 , wherein

the stator includes an insulator between the coil and a tooth around which a conductive wire defining the coil is wound; and

the insulator includes a lead wire holding portion that holds the lead wire.

7. The motor according to claim 1 , further comprising:

an intermediate member positioned between the stator and the bus bar holder; wherein

the intermediate member includes a lead wire holding portion that holds the lead wire.

8. The motor according to claim 7 , wherein the stator includes:

teeth around which a conductive wire defining the coil is wound, and which are arranged in a circumferential direction; and

an annular core back located radially outside of the plurality of teeth;

the core back includes a groove portion recessed radially outward and axially extending on a circumferential surface;

the intermediate member includes:

an annular portion provided with the lead wire holding portion on an upper surface thereof; and

a rib protruding radially inward from a circumferential surface of the annular portion and protruding downward from an axially lower end of the annular portion; and

the rib is fitted into the groove portion.

9. The motor according to claim 7 , wherein the intermediate member includes a first overhanging portion protruding radially inward in a circumferential position where the lead wire holding portion is provided.

10. The motor according to claim 7 , wherein

the lead wire holding portion holds a plurality of the lead wires; and

the intermediate member includes a second overhanging portion protruding radially inward from the lead wire holding portion.

11. The motor according to claim 10 , wherein

the lead wire holding portion includes a wall portion separating the plurality of lead wires from each other; and

the second overhanging portion is located radially inside of the wall portion.
