Description
technical field [0001] The invention relates to a generator for simultaneously measuring rotational angular velocity and angular acceleration, and more particularly relates to a shaft sleeve type generator for simultaneously measuring instantaneous rotational angular velocity and angular acceleration. Background technique [0002] Rotational angular velocity and angular acceleration are two very important dynamic angular parameters. Through the measurement of angular velocity and angular acceleration, the response of the rotating system shaft to various excitations can be analyzed. Therefore, the measurement of rotational angular velocity and angular acceleration has been widely used in many fields such as automobile, military, aerospace, industry, and electronics. [0003] At present, the commonly used generators for measuring instantaneous angular velocity are mainly divided into two categories: DC tachometer generator and AC asynchronous tachometer generator. When the DC ...
