Abstract
In an armature, the upper and lower coil pieces in one half of the parallel circuits are located at the 1st, 4th, 6th, 7th, 9th, 12th and 14th positions, and the upper and lower coil pieces in remaining half of the parallel circuits are located at the 2nd, 3rd, 5th, 8th, 10th, 11th and 13th positions, when relative positions of the upper and lower coil pieces in each phase belt are indicated by positions counted in a direction separating away from a pole center.

An armature comprising:
- an armature core with slots;
- and
- an armature winding that is housed in the slots, wound in two layers, and provided with fourteen coil pieces per pole and phase, each phase of the armature winding divided into two phase belts, one phase belt per pole, each phase belt having two parallel circuits, each parallel circuit having a serial coil, each serial coil having upper coil pieces and lower coil pieces connected to each other at a connection-side coil end and a counter-connection side coil end,
- the upper and lower coil pieces in one half of the parallel circuits being located at the 1st, 4th, 6th, 7th, 9th, 12th and 14th positions, and the upper and lower coil pieces in remaining half of the parallel circuits being located at the 2nd, 3rd, 5th, 8th, 10th, 11th and 13th positions, when relative positions of the upper and lower coil pieces in each phase belt are indicated by positions counted in a direction separating away from a pole center.
