Torque is an important parameter in ensuring motors are well suited to their intended service. This article demonstrates how to calculate torque for a given motor or drive, and provides a brief introduction to motors and torque.
The moment of inertia of a pump is its resistance to changes in angular velocity as it rotates about its shaft. Knowledge of the moment of inertia of a pump, motor and associated components is typically required for transient analysis of a pumped system. This article presents methods by which pump and motor moment of inertia may be estimated.
