Abstract
A motor includes a stator core and coils. Teeth of the stator core include a first tooth through a k-th tooth (where k is an even integer). The coils include first coils through k-th coils n-th coils (where n=1 to k) are wound around an n-th tooth. In each of the n-th coils, the number of windings passing through one slot adjacent to the n-th tooth is larger than the number of windings passing through another slot adjacent to the n-th tooth. The coils included in the first coils through the k-th coils are connected one by one in series via a crossover wire to repeatedly turn in ascending order from the first.
Claims12
A motor comprising:
- a stator core including teeth and slots alternately arranged in a circumferential direction about a predetermined rotation axis;
- and
- coils wound around the teeth, wherein
- the teeth include a first tooth group including a first tooth through a k-th tooth (where k is an even integer),
- the coils include a first coil group including first coils through k-th coils,
- the first coils through the k-th coils are in the same phase,
- n-th coils (where n=1 to k) are wound around an n-th tooth,
- in each of the n-th coils, the number of windings passing through one slot adjacent to the n-th tooth is larger than the number of windings passing through another slot adjacent to the n-th tooth, and
- coils included in the first coils through the k-th coils are connected one by one in series via a crossover wire to repeatedly turn in ascending order from the first.
A motor comprising:
- a stator core including teeth and slots alternately arranged in a circumferential direction about a predetermined rotation axis;
- and
- coils wound around the teeth, wherein
- the teeth include a first tooth group including a first tooth through a k-th tooth (where k is an even integer), and a second tooth group including a (k+1)th tooth through a (2k)th tooth,
- an n-th tooth (where n is 1 to k) and an (n+k)th tooth are adjacent to each other,
- the coils include a first coil group including a first coil through a k-th coil, and a second coil group including a (k+1)th coil through a (2k)th coil,
- the first coil group and the second coil group are in the same phase,
- an n-th coil is wound around the n-th tooth,
- an (n+k)th coil is wound around the (n+k)th tooth,
- in the n-th coil wound around the n-th tooth, the number of windings passing through one slot adjacent to the n-th tooth is larger than the number of windings passing through another slot adjacent to the n-th tooth, and
- in an (n+k)th coil wound around the (n+k)th tooth, the number of windings passing through one slot adjacent to the (n+k)th tooth is larger than the number of windings passing through another slot adjacent to the (n+k)th tooth.
