Abstract
The present method can determine the inertia of an electric motor and the load driven by the electric motor in situations where the electric motor accelerates or decelerates in a non-linear manner. During acceleration and deceleration, the torque produced by the electric motor is sampled periodically and the average values for the acceleration torque and deceleration are calculated. The rates of acceleration and deceleration also are determined. These values are employed to derive a value indicating the inertia.
