SYNCHRONOUS ELECTRIC MOTOR Russian patent published in 2013 - IPC H02K19/06 H02K1/06 

FIELD: electricity.

SUBSTANCE: in the proposed synchronous electric motor "П"-shaped magnetic conductors (1) of the stator are made as laminated from electric steel and are combined into a single structure with the help of two rings (3), made of non-magnetic material. On each "П"-shaped magnetic conductor (1) there is a phase (2) of stator winding. The rotor (4) is made of ferromagnetic material, installed on the shaft (5) and has a cylinder shape with two teeth displaced along the axis and having identical angular position. At the same time supply of stator winding phases is carried out with AC voltages shifted by phase to the angle that is less than the space shift of "П"-shaped magnetic conductors.

EFFECT: production of increased speed of rotor rotation of a synchronous electric motor when supplied from a multi-phase network.
