RU2349015 ASYNCHRONOUS MACHINE

FIELD: electricity, wind power

SUBSTANCE: invention relates to electrical engineering and may be used in other engineering branches, for example wind-power engineering. The main point of the invention is the use of specific common rotor in asynchronous machine with two stators and common rotor. The above-mentioned common rotor rotates freely with regard to the shaft and at the same time has two separate short-circuited windings for each stator and one common short-circuited winding for both stators. One stator is fixed to the shaft, while the other rotates together with it. The windings of the fixed stator and the stator rotating together with shaft are made up from windings of two or more unequal sections of the above stators. In addition, the minor sector of the fixed stator winding and the minor winding sector of the stator rotating together with the shaft are connected to the mains. The same connection is ensured for large sectors or next by the size sections of the fixed stator or stator rotating together with stator shaft.

EFFECT: increase of electromagnetic moment at smaller dimensions, while ensuring moment control.
