ELECTRIC ENGINE Russian patent published in 2006 - IPC H02K19/06 

FIELD: electric engineering, namely, engineering of electric machines, in particular, electric engines, possible use, for example, for steering servo of an aircraft autopilot for manufacturing simplified electric engine with higher specific energy coefficients.

SUBSTANCE: electric engine consists of rotor with magnetic drive, shaft, bearing lids of non-magnetic material, stator, having U-shaped poles, positioned radially and evenly along circle. Engine is made of two stator parts. Each part of stator is made of one winding, U-shaped poles, positioned on own frame, made of cylindrical part and side walls with radial slits, carrying U-shaped poles. Frames are connected by ends. Poles of one part of stator are positioned in the middle between polar space of another stator part. Rotor poles are magnetically connected to poles of each stator part, are made of same set of rectangular poles with height of side plates being less, than height of middle plates forming additional shelf. Poles of rotor are mounted along engine axis, in slits of non-magnetic bushings, pinned on a shaft on both ends, held in upper part and on end sides. Each frame is made of dielectric material with low heat expansion coefficient. Side walls of frames are made in form of flat thin discs, outer surfaces of which are made with projecting ribs for mounting and holding stator poles on them. Frames are connected by ends and equipped with holding ring and coupling screws, ends of which are held in bearing lids. Value of air gap between rotor and stator poles ranges from 0,25 to 0,8 millimeters. Transverse width of middle plates of rotor poles, forming a shelf towards air gap, is limited by 80-85%. Engine can be made with three-positioned or neutrally positioned switch and with diodes connected to beginnings of windings, or with enabling two-polar device.

EFFECT: increased reliability, simplified construction, increased specific energy coefficients.
