Hello CWatters,
Indeed, if we take real-life conditions into account, then things get more complicated. But with this calculation I just wanted to get the ballpark torque value (in almost ideal conditions).
Andy,
Thanks for answering!
The motor you are refering, has a max torque of 4650 in-lbs. Is in-lbs the same as in-lbf?
Because if it is, then it`s equal to approx. 500 Nm, which is about 6 times less than needed according to my calculation..
Hello berkeman,
Thank you for your answer!
By rolling friction I meant indeed the resistance which is caused by the deformation of the tires (my physics vocabulary in english is poor :) ). The formula I used, is from a mechanical engineering handbook. And I would think that the friction in the...
Hi,
I need to choose a hydraulic hub motor for a vehicle which weighs 25 000 N when fully loaded. The vehicle must be able to start moving (fully loaded) on a inclined surface (30 degrees angle). So I need to determine the torque needed to get vehicle moving. The vehicle has three wheels from...
