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.
