ELECTRIC MACHINE WITH HIGH EFFICIENCY WITH SALIENT POLES AND METHOD OF ITS MANUFACTURING Russian patent published in 2015 - IPC H02K1/24 H02K1/32 H02K9/04 

FIELD: electricity.

SUBSTANCE: invention relates to electric engineering, in particular to electric machines with salient poles, including generators and motors. The suggested electric machine with salient poles includes rotating field assembly having curved outside diameter and including one and more rotor poles, windings and rods supporting coil, and winding section projecting beyond the rotor poles, and at least one cap of end face turn connected with rotating field assembly and surrounding coil supporting rods and windings section projecting beyond the rotor poles such that to reduce ventilation losses. At that this cap of the end face turn is made with the outside diameter mainly equal or similar to outside diameter of the specified rotating field assembly, and the rotating field assembly includes the open air cavity between the rotor poles and winding supports.

EFFECT: efficiency increasing of the electric machines with salient poles by means of the ventilation losses reduction.
