Abstract

In a directional drill rod having its own electrical power supply from an integrated generator (29), whose stator (30) is integrated in a stationary outer tube (2, 25), while the rotor (30) surrounds a concentrically inner drilling shaft, the invention is characterised by a brushless three-phase synchronous generator whose stator has two axial windings (33, 34) which are arranged axially one behind the other and have their own connecting leads (37, 38), of which one connecting lead is used for the power supply of an electro-hydraulic pressure generator (19, 20) and the drives (15, 20) of the directional controller, while the connecting lead of the other stator winding carries the power supply for the control electronics, the excess power of the generator (29) being destroyed electronically. <IMAGE>
