1 O O T S Y N S O L I D O T O E S O L V E Solid rotor, variable reluctance, frameless, brushless resolvers for severe applications. dmotec O Series otasyn 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 otasyn 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. nd the solid rotor allows operation with the rotor immersed in hydraulic oil or other liquids. The otasyn resolver is mechanically and electrically compatible with traditional brushless resolvers and can replace them as original equip ment or in existing applications. nd if our standard products don t meet your needs, custom versions can be quickly designed for your application. dmotec motion and position sensing for original equipment manufacturers. dvanced Motion Technology TYPIL PPLITIONS Industrial tachometer Motor feedback ngle measurement erospace Downhole (oilwell) FETUES & BENEFITS Non-contact design ugged construction Solid rotor Lower impedance Fewer coils Functionally equivalent to traditional brushless resolvers bsolute over GENEL SPEIFITIONS High-speed spindles and D servo motors Flight control systems Hydraulic pumps Nuclear environments No wear or aging Tolerates vibration and shock Higher speed, lower inertia Better noise immunity Higher reliability Higher performance replacement for obsolete or unavailable devices No homing at power up Operating Temperature Oxxxx-M to +75 Oxxxx-K 9 to + Shock G Vibration G ( 5 Hz,.5 Hr) adial ir Gap. mm nominal Excitation Frequency 5 to typical khz recommended Excitation mplitude to Vrms typical.5 V/V ±% ngular Error* ± arc-minutes typical ± arc-minutes maximum Insulation esistance MΩ minimum Dielectric Strength (Hipot) Winding to Winding Vac (5Hz for minute) Winding to Housing 5 Vac (5Hz for minute) Lead Wire Size WG Lead Length mm * Every otasyn shipped with an individual accuracy report.

6 O O T S Y N S OF OPETION Secondaries otasyn ef Solid otor /D onverter Sin B os Secondary Primary USTOM OTSYNS The otasyn is similar to a rotary variable differential rotary transformer (VDT) in which the rotor acts as a magnetic valve completing the flux path. The total flux through the D gap is constant the rotor determines the angular position within the stator bore where the coupling occurs, and thus the relative amplitudes of the output signals. otasyn Series 5 (Size ) onnection Diagram ELETIL SHEMTI otary Transformer Sin Output In addition to the standard versions, Series O otasyn (Secondary) resolvers may be fully customized to your needs. vailable otary customization options include (but are not limited to) Transformer those shown below. ontact us with your requirements for customized versions. otor Input (Primary) Size 5,, 5, and and larger models ustomized housings for different stator mounting Larger airgap (up to mm) Flooded rotor to eliminate rotating seal Different windings for modified electrical characteristics E θ S (ed) Secondary (osine) Primary (Yellow/White) S (Black) S (Yellow) E S O L V E otasyns can be used directly with all commercially available esolver-to-digital (/D) converters to provide information. digital angle and speed Digital Position Data (ed/white) TYPIL PPLITION. Unlike traditional brushless resolvers, the otasyn has both primary and secondary windings in the stator and thus no transformer is required the otasyn is intrinsically brushless.
