THREE-PHASE SYNCHRONOUS MOTOR Russian patent published in 2011 - IPC H02K21/16 H02K1/27 H02K21/02 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electric engineering and may be used in three-phase machines with excitation from permanent magnets. Proposed three-phase synchronous motor consists of three-phase stator, winding of which create rotary magnetic field, and rotor, which comprises bushing of non-ferromagnetic material, strip of excitation from ferromagnetic plates with layers of plates of permanent magnets and additional poles of ferromagnetic material with layers of non-ferromagnetic material installed along radial axes of additional poles.

EFFECT: provides for maximum efficiency of motor determined by ratio between useful mechanical capacity developed by motor (P_{mech use}) and electric power consumed by motor (P_{el cons}).
