ADMOTEC - Model DG -Solid rotor duplex brushless resolver for severe applications
Admotec RO Series Rotasyn variable reluctance frameless resolvers provide high performance in measurement and feedback applications where traditional resolvers fail. Perfect for aerospace, down-hole, nuclear, and other severe applications, these solid-rotor resolvers offer original equipment manufacturers reliable solutions at any quantity—from prototype units all the way up to highvolume production. The Rotasyn has fewer parts and a solid rotor without windings, making it much simpler than traditional brushless resolvers. Since the solid rotor has no coils and the stator has only half the number of windings of a traditional brushless resolver, reliability is significantly increased. And the solid rotor allows operation with the rotor immersed in hydraulic oil or other liquids. The Rotasyn resolver is mechanically and electrically compatible with traditional brushless resolvers and can replace them as original equip ment or in existing applications. And if our standard products don’t meet your needs, custom versions can be quickly designed for your application.
