ABSTRACT:
A joystick mechanism generates output signals corresponding to the X and Y components of a manual command. A transducer mounted in a housing includes a ferromagnetic vane member connected to the bottom of a handle extending into the housing. The transducer also includes a stator member having nine legs mounted in a 3 by 3 rectangular array. The primary winding is wound around the central leg. Two pairs of opposed secondary windings are wound around each set of three outside legs, wherein the X-axis is disposed between one pair of secondary windings and the Y-axis is disposed between the other pair of secondary windings. Primary windings may be wound around the central three legs to form a symmetrical cruciform. The handle can be fixed to a deformable top plate or be supported at a rigid top plate by a ball and socket.
