Device with a stator having high performance flat coils

A device with a stator having high performance flat coils comprising:

• a stator tooth portion being punched by silicon steel pieces and having a tooth face having a cambered surface, an tooth root end extending backwards from a center of the cambered surface;
• a distal end of the tooth root end being extended outwards with a tooth root distal end which is not larger than a maximum width of the tooth root end;
• a T shape wire groove seat being made by insulator and having a T shape;
• a longitudinal vertical post thereof providing to be engaged with the coils of a motor or a generator;
• an interior of the longitudinal vertical post being hollow and being engagable with the stator tooth root end;
• and the hollow portion being a hollow end of the wire groove seat;
• and
• a flat coil being a flat wire;
• a thickness of the flat wire being determined by a depth of the longitudinal vertical post of the T shape wire groove seat divided by the number of winds of a rated rotary speed so as to acquire a thickness dividing number;
• a thickness of the flat wire should be smaller than a thickness dividing number so as to assure that a total thickness of the flat coil after winding is slightly smaller than the depth of the longitudinal vertical post of the T shape wire groove seat;
• the width of the flat coil being slightly smaller than a width of the winding space of the T shape wire groove seat;
• the flat wire being used in a standing form and being used with a “winding machine” for winding with a layer or multiple layer of windings;
• the shaped flat coil being further engaged with the longitudinal vertical post of the T shape wire groove seat;
• and moreover, a distal end of the flat coil being installed with an insulating piece.
