A gyroscopic sensor using active magnetic bearing (AMB) is studied in this paper. This sensor has been proposed to realize a compact, high-accuracy, multi-axis, and low-cost sensor. It utilizes the control function of AMB and works as a two-axis gyroscopic sensor and also as a three-axis servo-type accelerometer. Angular velocity measurement is focused in this paper. Angular velocities are estimated from the control signals for canceling gyroscopic and inertial torque acting on the shaft of AMB. In measuring two-axis angular velocity simultaneously, there is the upper limit to the measurement range since the estimation equation has zero as a frequency. Several numerical simulations and experiments with a conventional-size AMB are used to investigate the properties of the zero extensively.
