No one?..

Hello guys, I'm working for a home project and I want to made a simulation on a BLDC motor, which have a wheel attached to it's axle. (It is a part of small cart, 2 BLDC motors with 2 wheels directly mounted on the axle). So can I control the torque this way? What regulator should I use? How to...

I have the speed of the motor axle is spining, in rad/s, if I have the wheel directly on that axle, or a hub-motor (segway), can I use that value?

Yes, but how do I convert it? And btw I want it to rest...

If I have the wheels mounted directly on the BLDC motor axle, how should I calculate the wheel torque? I ask this because, if I send the command to the motor, e.g. 5 Nm necessary to keep the vehicle steady on the incline, how do I get the feedback for the control loop? So, if I calculated that...

Could you repeat please? I understand a little slow I guess :D

Ok, what is the condition for acceleration? I mean, how should I calculate the torque for starting from resting on the slope (previous case), to move uphill?

So, I have too add this to my stationary torque? Torque= ( m*g*sin_angle+(m*g*cos_angle*Crr) +Fa)*wheel_radius*resistance_factor?

And for going uphill?

Yeah I know, I was just curious how can I do that in future.

Yes, I want to find the torque of each wheel as a function of those variables. Hope it helps; Do you know to should I calculate the rolling resistance on a slope?

Right here, in my case FWD.

And in up motion, I will use this for calculating the max angle. And one more question, the calculation from that document, are valid for an angle smaller than maximum angle? Thanks!

Ok, I used the steps described in that document, without Fa and RR, because there is no rolling, and no speed? Is this correct?

Yes, kind of.
