Abstract
Provided are a coil capable of enhancing heat dissipation performance and/or voltage resistance, and a stator and a motor using the coil. A coil includes a helical structure body made of strip-shaped flat conductors that are continuously joined into a helical form. In the helical structure body, a first turn of helix is separated from a second turn, which is continuous to the first turn, at a preset interval.
Claims15
A coil comprising a helical structure body made of strip-shaped flat conductors that are continuously joined into a helical form, wherein
- in the helical structure body in a completed state, a first turn of helix is separated from a second turn, which is continuous to the first turn, at an interval preset to fulfill a prescribed function by a spacer, wherein a hollow gap is secured between the first turn and the second turn;
- and
- the spacer is constituted of at least a first portion of the flat conductor located on the first turn and is insulated from the opposing second turn, the first portion of the flat conductor has a first length in a helical traveling direction, and the flat conductor has a second portion without the spacer having a second length in the helical traveling direction greater than the first length of the first portion.
