Title:
ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2009/157888
Kind Code:
A4
Abstract:
The invention relates to alternating and direct-current electric motors and can be used in electrical drills for drilling wells, in particular oil and gas wells. The inventive electric motor comprises a rotor, a shaft, a stator, a current lead, brushes conjugated with slip rings, wherein the stator is not fixed but is secured in bearings and rotates around the rotor (fixed or rotating). The inventive electric motor makes it possible to perform mechanical work by means of the rotating rotor and the rotating stator (alternately or simultaneously). The use of said electric motor, in particular, as an electric downhole motor in the drills for drilling wells, makes it possible to carry out drilling without drill pipes, whereby substantially reducing the cost and increasing the operational efficiency of drilling.
