ABSTRACT:
A six axis joystick (110) employs a 13 pole E-core (112) that includes a center pole (114) and four triads of outer poles (116, 118, 120, 122) that protrude from four orthogonally separated arms (124, 126, 128, 130) of the E-core. A drive winding (132) is wound around the center pole of the E-core, and sense windings (134, 136, 138, 140) are wound around each outer pole in each triad of outer poles. A compression spring (144) suspends a ferromagnetic swash plate (142) at substantially equal distances from the center pole and each of the outer poles. A user employs an actuator handle (148) to axially and rotationally deflect the swash plate to assume varying distances from the center pole and each of the outer poles. A varying magnetic flux induced by the center pole is conducted through the swash plate to each of the outer poles to a degree dependent on the spacing between each outer pole and a bottom surface (146) or a periphery (147) of the swash plate. Corresponding signal currents are induced in the sense windings. Each of the signal currents is proportional to the degree of magnetic flux flowing in its associated outer pole. A peak amplitude is detected for each signal current and the differences among the peak amplitudes are used to determine a degree of deflection of the swash plate in each of the X-, Y-, Z-, roll-, pitch-, and yaw-axis directions.
