Abstract

Elektromotor egnet for innmotering i brønnrør for anvendelse ved boring og pumping, og med 'en drivaksel (4) med påmonterte, adskilte rotorskiver (6) som drives av ringformede statorviklinger (7) som er forbundet med motorhusveggen. Viklingene (7) er anordnet som lineærmotorer som drives på en sirkulær bane, og viklingene kan energiseres på en slik måte at akselen påføres en aksialbevegelse, for oppnåelse av slag- eller bremsevirkning. Akselen (4) kan være rørformet for å avgrense en kanal for boreslam eller for et fluid som pumpes.Electric motor suitable for mounting in well tubes for use in drilling and pumping, and with a drive shaft (4) with mounted, separate rotor washers (6) driven by annular stator windings (7) connected to the motor housing wall. The windings (7) are arranged as linear motors which are driven on a circular path, and the windings can be energized in such a way that the shaft is applied to an axial movement, in order to achieve impact or braking action. The shaft (4) may be tubular to define a channel for drilling mud or for a fluid being pumped.
