FREQUENCY-CONTROLLED ASYNCHRONOUS ELECTRIC DRIVE Russian patent published in 2005 - IPC

Abstract RU 2253940 C2

FIELD: electric engineering.

SUBSTANCE: device has electric engine with arc windings of stator, electric engine speed detector and adjustment system, containing static frequency converter with autonomous inverters, individually connected to arc windings of stator, and transformer control block, having check connection to electric engine speed detector and direct connection to static frequency converter. Electric drive is provided with no less than two electric engines with arc windings of stator , to separate autonomous inverter a group of arc stator windings is connected, one from each electric engine, and number of autonomous inverters is equal to number of arc windings of stator of single electric engine.

EFFECT: simplified construction, decreased number of autonomous inverters for one electric engine while maintaining required operation characteristics of current electric engine.
