The moment of inertia of the step motor
If the inertia is small, it's because of the structure. Because the stepping motor is the high precision motor. The motor runs to stop, usually in a short amount of time. This causes the object to overshoot. So we need to reduce the inertia. It's usually damped by a decelerator. Or other ways. Of course, if the force needed is very small, you can use less than 10. But your 10 is unitless and fuzzy.
Step inertia of step motor: The inertia of the step motor is usually associated with the starting frequency. In general, the higher the inertia of the start and stop frequency, the suggestion is to use the low inertia motor or the lower drive current, the voltage. If the object of a rectangular cube is flat, the surface of contact is large, and the force of friction is greater. Friction is the ability to overcome inertia. The force of friction is usually greater than the inertia of the step motor.
It is generally close to the inertia of the motor or the inertia of the motor. If it is greater than the inertia of the motor, the electric opportunity will overshoot. You don't have to say that you're less than the motor. If it is greater than the inertia of the motor, it is suggested to reduce it by reducing the engine.
