Hey so I am buying this motor:
robotshop.com/en/cytron-12v-34rpm-139oz-in-spur-gearmotor.html
But the specs are throwing me off. The title says 139 OZ-in but the stall torque is 500 oz-in. Then the rated torque is at 125 oz-in. I’m just confused if this motor could meet my specs. I would be operating at 33.75 RPM with roughly 125 oz-in of torque. Would this motor work? We may go above 125 oz-in, but generally will stay at 125. Are these specs correct?
Thank you!
Hi,
We agree that the title is misleading, we are in the process of correcting these inconsistencies.
To answer your question, yes this motor should run at around 34 RPM @ 12 V with around 138 oz-in of torque.
By running at 33.75 RPM it will probably give a bit more than 125 oz-in, if that is not an issue it will be fine.
Hope this helps !
Would this be a problem for the motor? If the motor is capable of running at that torque then it would be even better than the previous calculated value. But if it’s at risk of burning out then I would probably have to look for another motor.
Hi,
Since this is the rated specification of the motor, it will be able to handle a lot more than this before burning out.
A DC motor will burn out when used for a long period of time at a higher voltage than recommended, when stalled for too long or when it’s been used for too long and a replacement is needed.
If you plan to use this motor at 12 V, expecting it to run between 33-35 RPM while providing 130-140 oz-in or torque, it will be a perfect match.
