Abstract
The compact digital resolver/encoder assembly comprises a resolver and a flexible printed circuit board having a number of electronic components for decoding the resolver mounted on the flexible printed circuit board. A generally cylindrical container is provided having a cylindrical wall, a closed end and an open end. The circuit board is folded into a generally cylindrical shape and received in the container separate from the resolver. The circuit board is insulated from the container by an electrical insulating potting compound situated in the container and surrounding the circuit board. The resolver is received in the container and is spaced a predetermined distance from the encapsulated circuit board. Preferably a voltage regulator is mounted to an inside wall of the container and electrically coupled to the circuit board. Also, preferably, wire conductors between the resolver and the circuit board are longer than necessary to allow the resolver to be positioned outside the container when the potting compound is inserted in the container.
