## Main Question or Discussion Point

Hi,

A normal query regarding moviement of the wheel of an EV.

In the designing of an EV, I calculated the torque required to pull the wheel of my EV on normal surface as T=F*r (keeping in mind friction and other factors too),where 'r' is the radius of the wheel. Similarly, I calculate the torque for uphill and for clearing the obstacles. Now, the torque I calculated is the peak torque as I am using T=F*r, where F=M*acceleration, say during my normal operation of the EV on the normal surface, I require this much of torque to push or to provide a start to my EV, because its considering the acceleration here, now my problem is here that I want to consider the velocity of my EV, like after supplying the initial torque to the wheels, what is going to be the normal torque, say like my velocity is 1 m/s and radius is .3 m and acceleration is 1.5 m/s2. So basically, I want to know the torque require to push my vehicle for a certain time 't' and with a velocity of 1 m/s irrespective of the acceleration.

Any help would be of great help.

Thanks!!!

Dave
