Abstract

En motorenhet med flere motorer for bruk til å drive en del av en brønnhullsbelastning i en brønn, blir beskrevet. Enheten kan innbefatte motorer med hovedsakelig konstant justerbar hastighet. Disse kan innbefatte synkrone maskiner med permanentmagneter. Motorene kan være innrettet for å operere ved gitte hastigheter som kan justeres ned avhengig av størrelsen av dreiemomentutgangen uavhengig av de enkelte motorene. På denne måten kan et signifikant avvik i dreiemomentutgangen mellom motorene unngås for å sikre hovedsakelig lastfordeling mellom alle motorene i enheten.
