DOUBLE-CURRENT GENERATOR WITH COMPENSATION WINDING Russian patent published in 2010 - IPC H02K47/08 H02K29/08 

FIELD: electricity.

SUBSTANCE: in the proposed double-current generator for compensation of resultant mechanical motive force of armature in the commutation zone to the specified level there intended is independent compensation system which includes the following: in-series connected windings of auxiliary poles and compensation. Hall sensor for measuring mechanical motive force in commutation zone of machine is located on geometrical neutral under the centre of the tip of auxiliary pole. Hall sensor is connected to microcontroller input. There is controller power unit, power unit of windings of auxiliary poles and compensation winding with direct current. Invention provides direct measurement of mechanical motive force in commutation zone of machine by means of Hall sensor. Self-excitation of generator occurs during its start-up. Transformer of controller power unit is connected to linear voltage of generator. Power unit of windings of auxiliary poles and compensation with direct current consists of three-phase transformer connected to contact rings of generator, rectifier and pulse width converter to the input of which the control signal providing minimisation of resultant mechanical motive force in commutation zone of machine is supplied from microcontroller.

EFFECT: simplifying, increasing quick operation and reliability of control system, absence of external power sources.
