Abstract :
A high inertial load can cause significant operational problems of a paper machine due to excessive acceleration and deceleration times. A comparison of the electrical drive components with the load requirements is presented in order to determine the optimum drive rating to support the acceleration and deceleration times required by production. A graphical approach is used to simplify this procedure. It is shown that by plotting the load requirements and the power unit capabilities, the optimum drive rating can be determined based on the time required for acceleration and deceleration. For a given drive size and load requirement the maximum capability can be determined without guessing
