Leave the rotor inertia Jo and the gear ratio i blank if you have not selected any motor (or geared motor) yet. Then, fill in the rest of the form. The software will temporary calculate the acceleration torque with a load/rotor inertia ratio of 5:1.
Step 2 :
Select a product based on the required torque and the required speed. Then, confirm the inertia ratio to be within the recommendation. (See the motor selection tips that will appear on the result window for the detail)
Step 3 :
Return to the form and enter the rotor inertia Jo and the gear ratio i of the product you have selected to calculate the torque requirement using that particular product. If you selected a round shaft type motor (without gearhead), leave i blank or enter 1.
Rotor inertia Jo :
This value is found in the specification tables for stepping motor products.
Gear ratio i :
This value is the gear ratio of the geared motor product you selected.
* These values are only used to calculate a more accurate acceleration torque.
