摘要研制了一种新型旋转角加速度传感器校准装置。校准装置包括外定子、杯形转子和内定子,其中外定子两相绕组的轴线正交,输入的两相交流电错开90°相位差,产生旋转磁场后驱动杯形转子产生变化的角加速度量值;推导了角加速度量值的理论公式,给出公式所需参数的获取方法;最后采用光栅测角加速度系统对校准装置的特性进行了测定,结果表明装置产生的角加速度量值线性误差约为0.53%。

Abstract：A novel calibration device for angular acceleration sensor is designed. The calibration device is composed of outer stator, cup rotor and inner stator, the axis of two stator winding is orthogonal, and the AC in two winding stagger 90 electrical degrees each other, then a rotating magnetic field is generated, and result in the mutative angular acceleration produced on rotor. The theoretical formula of angular acceleration is deduced, the method of obtaining the parameters of the formula is given, and the characteristics of the calibration device are determined by the grating angular acceleration measurement system, the results show that the linear error of the calibration device is about 0.53%.

Key words： metrology angular acceleration rotating magnetic field ellipse calibration
