<p>A sensor (10) for measuring angular rate and linear acceleration of the body, in which first and second rotors (30, 31), each carrying a plurality of accelerometers (44, 49), are mounted for counter-rotating dithering motion on opposite sides of a base plate (11). A single permanent magnet (70) is mounted centrally of the base plate, with one pole (71) disposed adjacent the first rotor and the other pole (72) disposed adjacent the second rotor. First and second X-shaped pole pieces (80, 81) are mounted at the respective opposite poles of the magnet, and a plurality of velocity sensing pick-off coils (86) are mounted on the arms (82, 83, 84 and 85) of the pole pieces for cooperation with flux splitting protrusions (34, 35 and 36) on the rotors. The arms of the pole pieces are associated with the flux splitting protrusions so that differential flux splitting is obtained as the rotors are rotated in opposite directions.</p> |
