MAGNETOELECTRIC MACHINE WITH AUXILIARY MOTOR Russian patent published in 2014 - IPC H02K21/22 H02K1/06 H02K19/38 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, in particular, to electric machines. Technical result is achieved due to the fact that the design of the proposed machine involves an auxiliary motor with special excitation which undertakes part of load at the machine operation. First of all, the above is concerned with the fact that no back EMF (of currents) will be induced in the windings of its stator and rotor. Direct and return active wires of the windings of the respective anchors in the main generator and in the special exciter are laid in the grooves of respective magnetic conductors so that the pairs of positive and negative half-waves of the anchor currents in the main generator and in the special exciter which are induced in the operating mode are shifted by phase by 45°. The direct and return active wires of the main generator anchor winding are laid in the opposite grooves of the generator magnetic conductor in series and are a solid winding. The active wires of the movable armature in the special exciter are laid in the same way. Windings of all four salient electromagnetic poles of the auxiliary motor stator are coupled to each other in series and every adjacent ones are wound in opposite directions. The rotor windings are wound and connected in the same way.

EFFECT: significant improvement of start-up, adjustment characteristics as well as increased efficiency.
