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 (Pmech use) and electric power consumed by motor (Pel cons). ^ 5 dwg |
