Potentiometer Resolver

The potentiometer resolver utilizes two linear resistances and a wiper arrangement. It provides voltage amplitudes bearing sine and cosine relationships of an applied voltage relative to the angular displacement of a shaft.

Two linear resistance strips 10 and 12 are mounted perpendicular to each other with the common point 14 grounded. Terminals 16 and 18 of resistances 10 and 12, respectively, are maintained at positive voltage + Et. Terminals 20 and 22 of resistances 10 and 12 are maintained at negative voltage - Et.

Wipers A and B are constrained to move along resistances 10 and 12, respectively. Connecting bar 24 is pivotally mounted on wipers A and B in insulated relationship. The length of bar 24 is one-half the length of the resistances. The center point P of bar 24 is driven in a circle about common point 14, thus defining an angular displacement of a shaft through point 14. For an angle M defined by the line 26 through points 14 and P, the voltage at wiper A is Et sin B and the voltage at wiper B is Et cos phi
