• When a load is driven directly by the motor, the conversation around reflected inertia goes out the window. The belief is that direct driven loads do not, by their nature, have a reflected inertia. Some folks are even confident enough to say that the ratio of the load inertia to the motor inertia does not need to be taken into account when direct driving the load as long as you have enough torque and speed. I have never had enough confidence to make such a statement.
