Abstract
A coil insulation structure for a rotating machine provided in the present invention is based on a conventional insulation technology. In particular, tooth portions of an iron core in which coil windings are inserted have a straight tooth structure without a shoe portion, and a component with an insulation effect is further added at a position of an opening of a groove in which the coil winding is located, so that an insulation effect is improved, and at the same time an added insulation component is used to ensure a thickness and a size of an inner layer located at a position adjacent to an air gap of a motor when the coil winding is encapsulated, thereby improving product quality.
