Web4. dec 2024 · The rotational velocities and accelerations in the motor, caused by turning the output shaft, increase by r. Along with the acceleration, the reaction torque in the motor increases by the same amount. The reduction ratio will also apply on this torque and and hence increase it again by r at the output shaft. Share Improve this answer Follow Web15. nov 2024 · We use the term reflected inertia to denote the inertial load that is felt on the opposite side of a transmission, due to the scaling effect of the transmission. The "reflected inertia" of the arm at the motor is cut by the square of the gear ratio; or the "reflected inertia" of the motor at the arm is multiplied by the square of the gear ratio.
