Motor and compressor

1. A motor comprising:

a rotor; and a stator that generates a magnetic field to rotate the rotor, wherein

the stator includes

a plurality of teeth,

a plurality of winding wires including a winding portion wound around each of the plurality of teeth, a neutral wire provided on one end side of the winding portion, and a power wire provided on an other end side of the winding portion, and

a plurality of neutral points at which a set of three neutral wires corresponding to each of three phases is electrically connected via a connecting member, and

the set of three neutral wires includes a plurality of first fixation portions in which the set of three neutral wires is fixed to each other in positions that are on a side of the winding portion compared to the plurality of neutral points, and a second fixation portion in which a plurality of sets of the neutral wires is bundled and fixed to each other from the plurality of first fixation portions to the plurality of neutral points.

2. The motor according to claim 1 , wherein

in the plurality of first fixation portions, the neutral wires extended in a circumferential direction of the stator are twisted together and the three neutral wires are fixed to each other.

3. The motor according to claim 1 , wherein

the plurality of first fixation portions is arranged in vicinity of each other in a circumferential direction of the stator.

4. The motor according to claim 1 , further comprising

an insulator fixed to each end of the stator, wherein

in the plurality of first fixation portions, three neutral wires are routed and fixed together onto the insulator.

5. The motor according to claim 4 ,

in the plurality of first fixation portions, a neutral wire extended to one side in a circumferential direction of the insulator and a neutral wire extended to an other side in the circumferential direction together, are twisted and fixed.

6. The motor according to claim 1 , wherein

in the second fixation portion, the plurality of sets of the neutral wires respectively connected at the plurality of neutral points, is twisted together into a bundle.

7. The motor according to claim 1 , wherein

the second fixation portion is covered with an insulating member and is inserted into a gap between the winding portions adjacent to each other.

8. The motor according to claim 5 , wherein

the insulator has a notch that makes an outer peripheral side of the insulator and the winding portion communicate with each other, and

the second fixation portion is inserted into a gap between the winding portions, which are adjacent to each other, from the outer peripheral side of the insulator through the notch.

9. A compressor comprising:

a motor that includes:

a rotor; and a stator that generates a magnetic field to rotate the rotor, wherein the stator includes

a plurality of teeth,

a plurality of winding wires including a winding portion wound around each of the plurality of teeth, a neutral wire provided on one end side of the winding portion, and a power wire provided on an other end side of the winding portion, and

a plurality of neutral points at which a set of three neural wires corresponding to each of three phases is electrically connected via a connecting member,

the set of three neutral wires includes a plurality of first fixation portions in which the set of three neutral wires is fixed to each other in positions that are on a side of the winding portion compared to the plurality of neutral points, and a second fixation portion in which a plurality of sets of the neutral wires is bundled and fixed to each other from the plurality of first fixation portions to the plurality of neutral points; and

a compression unit that compresses a refrigerant when the rotor rotates a rotating shaft.
