George Ellis, in Control System Design Guide (Fourth Edition), 2012. 16.3.1 Increase Motor Inertia/Load Inertia Ratio. Increasing the ratio of motor inertia to load inertia is one of the most reliable ways to improve resonance problems. This is because the smaller the ratio of load inertia to motor inertia, the less compliance will affect the system

2021-7-26 · Inertia is an object’s resistance to a change in speed. In an electro mechanical system, both the motor’s rotor and load have inertia, and how similar (or different) their inertias are will affect the performance of the system. The ratio of the load inertia to the rotor inertia is an important aspect of motor

2018-10-10 · Usually for a loaded motor, the inertia of the rotor is only a small part of the friction; a well made motor can start will a small current (the friction at the bearing is relatively small). But when you have to start the motor with load on, you need to apply far larger current to start

2021-8-11 · Inertia describes the tendency of a body to resist changes in rotational speed for a given torque. What is a typical ratio of the application load inertia to the motor inertia ? It is not unusual that the application load is in a range of 1:1 to 5:1 to allow highest loop bandwidth and dynamic response. The “inertia

2021-8-10 · For stepper motors or servo motors, you will need to know the allowable inertia ratio each type of motor can handle. For stepper motors, the general guideline is to keep the inertia ratio (load inertia or reflected load inertia divided by rotor inertia) under 10:1, and 5:1 for faster motion profiles or smaller frame sizes than NEMA 17.
