Armature winding, method for manufacturing armature winding, and slotless motor
First Claim
1. An armature winding comprising:
- a tubular member;
a first conductor, arranged in a radially inner side of the tubular member, for receiving current; and
a second conductor, arranged in a radially outer side of the tubular member, for receiving current;
wherein the first conductor includes a first coated portion, coated by an insulator, and a first wire connection portion, located at an end of the first coated portion and being free from the insulator, and the second conductor includes a second coated portion, coated by an insulator, and a second wire connection portion, located at an end of the second coated portion and being free from the insulator, the first wire connection portion and the second wire connection portion being electrically connected to each other.

Abstract
A first armature winding and a second armature winding each include a tubular member, a first conductor arranged in a radially inner side of the tubular member, and a second conductor arranged in a radially outer side of the tubular member. The first conductor includes a first coated portion, which is coated by a coating formed from an insulator, and a first wire connection portion, which is free from the insulator. The second conductor includes a second coated portion, which is coated by a coating formed from an insulator, and a second wire connection portion, which is free from the insulator. The first wire connection portion and the second wire connection portion are electrically connected to each other. A large output is obtained from a slotless motor including the first armature winding and the second armature winding.
