METHODOLOGICAL ERROR OF DISCRETE METHODS OF MEASURING CONSTANT ANGULAR ACCELERATIONS OF ELECTRIC MOTORS SHAFTS

Abstract

The article is devoted to methods of measuring angular accelerations and optimization of measurement errors of rotational parameters of electric motors. The main focus is on optimizing the process of measuring angular accelerations, reducing errors and improving the accuracy of such measurements. The article examines the factors that affect the methodical error, such as the choice of the fixed angle value, the moment of the start of the measurement, the technical means and the range of angular accelerations being measured. The dependence of the methodological error on various parameters is presented. In particular, cases are considered when the duration of constant angular acceleration is limited, as well as when there is a change in error during the time corresponding to a certain number of revolutions of the shaft that sets the constant angular acceleration.
