SYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2008 - IPC H02K19/06 H02K19/00 

FIELD: electric engineering, in particular - synchronous electric motors with reactive rotors, possible use in industrial, transportation and instrumental electromechanical systems.

SUBSTANCE: electric motor contains body (1), stator packet (2) with multi-phased winding (3), magnetic conductor of rotor (4) with teeth, shaft (5), alternating coaxial hollow cylinders of rotor (6) and stator (7), which consist of ferromagnetic (8) and non-magnetic (9) elements, which are positioned along the axis of rotation, where the cylinders of rotor are mechanically connected to magnetic conductor of stator through non-magnetic disk (10), and stator cylinders are attached to the body be non-magnetic bushing (11), while teeth of packet and ferromagnetic elements of rotor cylinders have their identical angular positions. Due to introduction of two additional layers of rotor and stator, an electric motor is produced with high mass and size characteristics, in other words, with increased momentum at the same size.

EFFECT: improved mass and size characteristics of synchronous electric motor.
