Abstract
Provided are a coil, a stator, and a motor that can suppress generation of eddy current in the coil and reduce Joule loss. A coil is formed by connecting a plurality of one-turn regions each including a turn of a conductor to have a helical structure. The conductor is formed by connecting a first member to a second member in a longitudinal direction, and the plurality of one-turn regions include at least in a part thereof the first member.
Claims9
A coil comprising:
- a plurality of one-turn regions stacked in a direction of a helical axis, wherein the coil is attached to a stator of a motor, and out of the plurality of one-turn regions, at least a part of a one-turn region near a rotor is constituted of a first member, and at least a part of a one-turn region far from the rotor is constituted of a second member, wherein:
- each of the one-turn regions is divided into a first half-turn region and a second half-turn region along a virtual cutting plane including a rotation shaft central line of the rotor;
- and
- in at least one one-turn region in the part of a one-turn region near a rotor, at least a part of the first half-turn region is constituted of the first member, and at least a part of the second half-turn region is constituted by the second member.
