DRILLING ELECTRIC GENERATOR Russian patent published in 2008 - IPC H02K7/18 H02K35/02 E21B47/22 

FIELD: electricity.

SUBSTANCE: drilling electric generator contains a stator, point of attachment, a rotor with one or several groups of permanent magnets, kinematically connected with the drive for the moving of the magnets, and the excitation windings corresponding to them. The drive for the moving of magnets is capable of reciprocative transportation and contains a power element from material with memory of the form. The power element can be executed in the form of bellows, from a material with memory of the form, established in an airtight cavity inside the stator to which are supplied wires from the excitation winding through the switchboard, to which is in turn connected the power supply and the accumulator of electric power. On the front part of the stator there is a ribbing. In a back part of the electric generator there is an electric socket connected by electricity cables with windings of excitation. Inside the point of attachment there are openings. The point of attachment is on the front part of the stator, or in the middle part of the stator, or at the back part of the stator.

EFFECT: increase in the power and resource with the reduction of its diametrical dimensions.
