Abstract
An electric machine provided with a stator structure including internal and external layers of interleaved pre-wound coils made of rectangular wire coated with enamel insulation varnish is described herein. The two layers of pre-wound coils allow the use of slightly different size of pre-wound coils, which facilitates their insertion into the stator slots.
