ELECTRIC MOTOR Russian patent published in 2009 - IPC H02K1/27 H02K21/12 

FIELD: engines and pumps.

SUBSTANCE: according to the first version of method realisation electric motor comprises rotor including rotor core inverted to stator and having multiple holes, in which magnets are inserted, at that rotor core has multiple protruding elements installed between external perimeter of rotor core opposite to stator and magnets and protruding in axial direction outside rotor limits. According to the second version, electric motor comprises stator and rotor including rotor core installed in stator with the possibility of rotation, in which multiple protruding elements exit rotor core outside its limits in axial direction, and multiple magnets fixed to rotor core. At that, every magnet has arc-shaped form convex in direction to rotor core centre, at that, every protruding element of rotor core is installed between stator and every magnet in radial direction of rotor, and every magnet embraces every protruding element of rotor core.

EFFECT: achievement of minimum losses in electric motor stator core, reduced production expenditures for increase of its efficiency, since protruding elements of rotor in axial direction exit periphery of core in rotor itself only facing stator, which provides for edge effect.
