I got this motor, here’s the link:
DC Motor Nominal Voltage: 12V No Load RPM: 5600 Stall Current: 15A Stall Torque: 48 oz-in Shaft Diameter: 5 mm Rear shaft length: 8.25mm
Price: USD 10.99
How can I know the maximum load in kg that it can handle (the mass)?
Can you help please?
Hello @user_as212,
The maximum load can be calculated from the stall torque as in the stall state this is the maximum load for the motor and you shouldn’t reach it.
So for calculating the load in Kg, you need to convert the oz-in unit into Kg-cm
Kg: The load in kilograms
cm: The distance between the motor shaft and the load.
However, the rated torque for this motor is 7.4 oz-in which means a load of about 0.5 kg.
Let us know if you have any further questions.
Sincerely,
Hello,
Thank you so much for your help. I also wanted to ask if I want to calculate the flywheel attached to this motor using T=Ia, a is alpha angular acceleration. Do I use the rated torque in T?
Hello @user_as212,
Thank you for your reply.
You should always do your calculations with respect to the rated values as the maximum values are only acceptable for a short time not for a long time run.
This discussion will help you with your project.
Let us know if you have any further questions.
Good Luck
