Term

Explanation

Load inertia

The total moment of inertia which is closer to the load than the given point on the shaft (sum of moments of inertia from the mechanics and from device characteristics).

Motor inertia

The total moment of inertia which is closer to the motor than the given point on the shaft (sum of moments of inertia from the mechanics and from device characteristics).

Inertia ratio

The ratio of load inertia and motor inertia (load inertia divided by motor inertia).
