When to use gears to change the inertia ratio of a motor-driven …

15/5/2019· Adding a gear set or gearbox between the motor and the load can improve the load-motor inertia ratio. Image credit: Omron Industrial Automation If the inertia of the load is significantly higher than the inertia of the motor, the load will essentially try to “drive” the motor, and the motor will have a difficult time achieving the desired position (or speed or torque).
