ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K21/22 H02K1/27 H02K5/04 H02K7/09 

FIELD: electrical engineering.

SUBSTANCE: electrical machine comprises stator support body, stator laminated sore with grooves made at its outer cylindrical surface for station winding coil windings to be fitted therein. Stator support body is composed of cylindrical barrel with sidewall mid part provided with cylindrical ledge. Stator is arranged inside rotor cylindrical cavity. Rotor comprises inductor composed of permanent magnets and ferromagnetic strips. Rotor body is composed of two opposed plates secured with cylindrical shell. Inductor is arranged at rotor body periphery. Its trapezoid-shape permanent magnets and parallelepiped-shape ferromagnetic poles are composed of plates directed in rotor lengthwise axis. These are arranged to make a composite ring with alternating pole polarity. Electrical machine comprises radial and axial thrust magnetic bearings. Stator parts of said magnets are secured at the ledge cylindrical surface are magnetised to build the Halbach array.

EFFECT: increased peripheral rate of inductor, simplified design.
