Abstract

The present invention relates to a device for engine stator, an electric engine and a method isolation coil engine stator. Specifically, the present invention includes an electric conductor wire coil, wherein a set of blade plates is inserted, a first insulating plate and a second insulating plate are arranged in a first region And a second region of the coil, so that the insulating plates are intermediated by an insulating means formed of air wherein, in the device, the plates do not make physical contact. The present invention relates to the field of engine manufacturing, electrical engineering and electric engines.
