Abstract

En unipolar reluktant vinkelføler som omfatter en rotor i magnetisk material og med et sylinderformet legeme (10) som på en første ende har et laminert parti (13) med samme antall rotorfliker (13A, 13B) som føleren har polpar, og på en annen ende har en ring (14). Vinkelføleren har videre en stator (20) i magnetisk material og som er utstyrt med et sylinder- formet parti forsynt med en eksiteringsspole (35) som strømforsynes fra en vekselspenningskilde. Forøvrig er statoren utstyrt med en første ring (22) forsynt med spor (23) og anordnet på en slik måte at den første ring sammen med rotorens laminert parti (13) danner et første luftgap (31), samt en glatt annen ring (24) som sammen med rotor- ringen (14) danner et annet luftgap (32). Statorsporene (23) er forsynt med en vikling som er påført slik at den spenning som induseres i viklingen er sinuslignende og fri for ' harmoniske, samt omhylningskurven for nevnte spenning representerer rotorens stilling i forhold til statoren, bortsett fra en viss faseforskyvning.
