Abstract
An armature including a core that includes plural teeth extending in a radial shape, and that has a slot formed between each of the plural teeth; a plurality of first winding coil sections formed by winding coil wire plural times spanning different respective sets of least two of the teeth, while shifting by one slot each time toward one side in the circumferential direction of the core; and a plurality of second winding coil sections formed by winding coil wire plural times spanning different respective sets of least two of the teeth, while shifting by one slot each time toward the other side in the circumferential direction of the core.
Claims7
An armature comprising:
- a core including a plurality of teeth extending in a radial shape with a slot formed between each of the plurality of teeth;
- first winding coil sections formed in a plurality of layers by winding coil wire a plurality of times spanning different respective sets of least two of the teeth, while shifting by one slot each time toward one side in the circumferential direction of the core;
- and
- second winding coil sections formed in a plurality of layers by winding coil wire a plurality of times spanning different respective sets of least two of the teeth, while shifting by one slot each time toward the other side in the circumferential direction of the core.
A manufacturing method of an armature comprising:
- a first process of, on a core including a plurality of teeth extending in a radial shape and with a slot formed between each of the plurality of teeth, winding a plurality of first winding coil sections by winding coil wire a plurality of times spanning different respective sets of at least two teeth, while shifting one slot each time toward one side in the circumferential direction of the core;
- and
- a second process of winding a plurality of second winding coil sections by winding coil wire a plurality of times spanning different respective sets of at least two teeth, while shifting one slot each time toward the other side in the circumferential direction of the core.
