Compact digital resolver/encoder assembly with flexible circuit board

A compact digital resolver/encoder assembly comprising a resolver, electronic circuitry for decoding the resolver being formed in at least one integrated circuit chip mounted on a flexible circuit board;

• a container having a closed end and an open end;
• said integrated circuit chip and circuit board being received in said container adjacent a wall of said container;
• said resolver being mounted in said container separate and spaced from said circuit board;
• and means for insulating said integrated circuit chip from said resolver and from said container.

A compact digital resolver/encoder comprising:

• a resolver;
• a flexible circuit board;
• a number of electronic components for decoding the resolver being mounted on said flexible printed circuit board;
• a generally cylindrical container having a cylindrical wall, a closed end and an open end;
• said circuit board being folded into a generally cylindrical shape and being received in said container;
• said resolver being received in said container separate from said circuit board and being spaced a predetermined distance from said printed circuit board;
• means for insulating said printed circuit board from said container;
• and an electrical connection including flexible insulated wire conductors between said resolver and said printed circuit board.

• a flexible printed circuit board;
• a generally cylindrical container having a cylindrical wall, a closed end and open end;
• said circuit board being folded into a generally cylindrical shape and being received in said container;
• said resolver being received in said container separate from said circuit board and being spaced a predetermined distance apart from said printed circuit board;
• and a voltage regulator which is fixed to said container inside said container so that said container can serve as a heat sink for said voltage regulator.

A compact digital resolver/encoder comprising:

• a resolver, a flexible printed circuit board;
• a number of electronic components for decoding the resolver being mounted on said flexible printed circuit board;
• a generally cylindrical container having a cylindrical wall, a closed end and an open end;
• said circuit board being folded into a generally cylindrical shape, being received in said container, and defining a central space;
• means for insulating said circuit board from said container;
• said resolver being mounted in said container within said central space and spaced a predetermined distance from said circuit board;
• and an electrical connection between said printed circuit board and said resolver, said electrical connection including insulated wire conductors which are longer than necessary for the connection but long enough for allowing said resolver to be positioned outwardly of said container when said circuit board is inserted in said container, after which said wire conductors are folded into loops and inserted into said central space with said resolver.
