109 moog components group ? www.moog.com 109 pancake brushless resolvers these units provide accurate position and velocity feedback as well as commutation in precision equipment, without the structural or temperature restrictions imposed by other electronic feedback devices. they are highly resistant to the shock and vibration levels often encountered in industrial environments, and do not require protection from the dirt, oil or other contaminants that normally occur in factory conditions. pancake brushless resolvers are supplied as separate rotor and stator assemblies, which are then mounted directly in the users system. since the energy is transmitted into and out of the rotor assembly by means of electromagnetic ?elds, no slip rings and brushes are necessary, reducing the cost and increasing the reliability of these devices. the pancake brushless resolvers are designed with larger than normal airgaps, in comparison with a standard pancake resolver, to allow for a greater degree of imprecision in mounting. normal considerations for these units require the rotor to be mounted inside the stator with an eccentricity no greater than 0.003 inch, and that the rotor and stator mounting surfaces be set in line within 0.020 inch. if eccentricities larger than 0.003 inch occur, the accuracy of the resolver will probably degrade; if the axial alignment exceeds 0.020 inch, input current, input power and phase shift will increase, while the output voltage drops. the mounting surfaces and the actual quantitative speci?cations for mounting, both concentrically and axially, may be found on the individual outline drawing for each unit type. normally, the housing assembly is held in place in the users equipment by the use of synchro clamps and the mounting grooves or ?anges provided on the outside of the housing. rotor assemblies are usually mounted adhesively, by using a keyway provided in the rotor bore, by clamping against the end of the hub, by set screws in tapped holes provided in the rotor hub, or by some combination of these methods. these low-cost pancake brushless resolvers are available in the standard sizes and con?gurations shown, or with custom modi?cations to either the given mechanical or electrical characteristics. our engineering department is available to assist you in tailoring these units to ?t the speci?c requirements of your system. resolvers
