ALTERNATING CURRENT ELECTRONIC MOTOR WITH CONSTANT MAGNETS Russian patent published in 2009 - IPC H02K29/00 H02K21/12 H02K1/27 

FIELD: electricity.

SUBSTANCE: invention refers to rotating electric machines and can be used in electronic or synchronous electric motors with constant magnets on their rotors. Alternating current electronic motor with constant magnets contains circular stator with multiphase winding and cylindrical rotor including shaft and circumferentially-spaced ferromagnetic strips. Each pole is formed by packs of laminated magnetic conductors of two adjacent segments installed on non-magnetic shaft, and each segment comprises top-flatted magnetic basement on which two packs of laminated magnetic conductor are mounted. Between the packs cavity is created for constant magnets installation whereupon the cavity is closed with non-magnetic plate. Above mentioned segments are installed on non-magnetic shaft with creation of non-magnetic gap between packs of laminated magnet conductors of adjacent segments comprising a pole.

EFFECT: reducing eddy-current losses in rotor magnet conductor and armature reaction whereupon increase in coefficient of efficiency of suggested motor is achieved.
