POWER GENERATOR OF WELL BEAM UNIT Russian patent published in 2013 - IPC H02K44/02 H02K5/12 E21B47/02 

FIELD: electricity.

SUBSTANCE: rotation of a counterweight of a cranking mechanism of a beam unit (BU) is proposed for transformation into rotary motion of a power generator stator around a rotor preserving the required weight characteristic of the transformed counterweight - power generator. According to this invention, the power generator stator is installed as capable of free rotation on the power generator axis around the rotor, and the rotor with the power generator axis is fixed in the lower part of a vertically located carrier, which in its upper part is installed as capable of free rotation on the horizontal axis of the outer master wheel, and due to gravity, is permanently in the vertical position, at the same time the master wheel is fixed in the cranking rod of the BU, and the stator serves as an inner slave wheel with smaller diametre and rotates several times faster than a cranking rod due to the fact that a master wheel rotates together with the cranking rod.

EFFECT: invention provides for generation of energy of higher capacity by a BU power generator.
