Generator for the production of electrical energy
First Claim
1. Generator for production of electrical energy to supply consumers located inside a bore hole, in particular, consumers for detection, transmission and remote control, where the generator is located in a flushing space inside of a drill string through which flushing liquid flows, which includes a stator and a rotor having a radial space arranged coaxially to the stator said rotor being coupled to a motor which is energized by the flushing liquid, said stator containing a generator armature and said rotor containing an exciter equipped with permanent magnet means, characterized by the fact that said space between stator and rotor is connected with said flushing space, a connecting path is directed counter-current to the direction of the flushing current on the intake side, and that said rotor is supported by means of unsealed, erosion and abrasion-resistant radial and axial bearings.

Abstract
Generator for production of electrical energy to supply consumers located inside a bore hole, in particular, consumers for detection, transmission and remote control, where the generator is located in a flushing space inside of a drill string through which flushing liquid flows, which includes a stator and a rotor having a radial slot arranged coaxially to the stator and whose rotor is coupled to a motor which is energized by the flushing liquid, characterized by the fact that the stator contains a generator armature and the rotor contains an exciter equipped with a permanent magnet, that said slot between stator and rotor is connected with said flushing space, where a connecting path is directed counter-current to or at an acute angle to the flushing current on the intake side in the region of a branch-off from said flushing space, and that the rotor is supported by means of unsealed, erosion and abrasion-resistant radial and axial bearings.
