BRUSHLESS ELECTRIC MACHINE Russian patent published in 2010 - IPC H02K21/12 H02K29/00 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and peculiar features of structural design of brushless electric machines, having several "loops" of magnetic flow, in particular comprising stator that includes several magnetically insulated electromagnet elements for interaction with several elements of rotor equipped with permanent electromagnets. Proposed brushless electric machine includes rotor and stator. Each of doubled poles of electromagnetic elements of stator corresponds to one of two magnetic poles of rotor magnetic assemblies. There are two air gaps arranged between stator and rotor for radial component to separate stator and rotor. Axial corresponding air gaps of axial component are located between stator poles and according rotor poles to separate stator and rotor poles. At the same time wheel-like ring of stator is partially surrounded with wheel-like ring of rotor.

EFFECT: invention provides for high efficiency and output power of brushless electric machine with simultaneous reduction of torque moment pulsations and achievement of safe flexible operational characteristics of this electric machine in process of its operation.
