ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K21/22 H02K1/27 H02K5/04 H02K5/16 

FIELD: electricity.

SUBSTANCE: proposed machine comprises stator support housing, stator laminated core with grooves to receive stator winding coils, rotor including body and inductor and bearing assy. Support housing is composed of cylindrical barrel with sidewall mid part provided with cylindrical ledge for stator core secured thereto. Stator is arranged inside cylindrical cavity of the rotor. Rotor includes body and inductor coil, which contains alternating permanent magnets and non-magnet wedges along perimeter. Rotor body comprises shell made of material with high magnetic conductivity and two detachable discs of non-magnet material joined to shell by their edges and faced towards each other with their cavities. Inductor coil is placed at peripheral area of the rotor body and its permanent magnets and non-magnet wedges are made as strips oriented along the longitudinal rotor axis and installed so that they form a multiple-piece ring with alternated polarity of magnet poles made of neodymium-iron-boron material, at that the strips are magnetised radially.

EFFECT: simplification of design and improvement of reliability.
