Abstract

PURPOSE:To widen a measurable range and improve resolving power by determining accelerations from the speed signal based on the time change of the phase shifting of a revolution deteting signal with respet to a reference AC signal, in a revolution accelerometer. CONSTITUTION:Primary windings 2A, 2C and 2B, 2D are wound on the exciting poles A-D of a stator 1, and are excited by the AC signals of phases shifting by 90 deg. with each other from oscillators 5, 6. A rotor 3 is offcentered from a revolving shaft 4, and according to revolving angles theta, the gaps from the respective magnetic poles change, thereby causing a change in reluctance for one period of since waves in one revolution. If the combined output of the induced voltages of the respective excting poles is deteted by secondary windings 7A-7D, the signal shifted of phase by the revolving angles theta with respect to the AC signals for excitation is obtained. During revolution, the theta is a function of time, and the speed signal is obtained from the change in the theta during one period. Accelerations are obtained by determining the change of the speed signal with time.
