The wheel does get pretty hot but it's all steel so that's not a big problem. I came across this motor curve.: It's not for my motor (I still don't have the exact specs of the motor) but if I understand correctly it shows that as motor load increases the watt input increases. That's what I was...

No, that's totally foreign to me. I know what current is and that's about it. I am about 90% sure that the power is being calculated with measured current and voltage. Essentially the wheel has a light brake on it. I want to increase the brake force but maintain rpm. It'll be difficult to make...

The wheel has a load but I want to increase the wheel's load and maintain its rpm. If I increase the load at the wheel will the motor maintain speed and draw more power? As far as cooling just natural convection cools the bearings.

So I guess if I increase the load at the second pulley that will increase the load at the motor pulley. The motor will either maintain rpm meaning that it is drawing more power, or else the motor will stall meaning that it can't provide enough power for that load/rpm configuration. Does that...

Howdy! I have a 10 hp motor on a machine but it's only using 3 hp while it's running. The output shaft of the motor is connected to a bigger pulley to spin a wheel. Is there any way to increase the torque at the wheel while maintaining rpms? My first thought was to use more of the motor power...

r is a constant because if you have a sphere, then r is a specific number. For example, a sphere of radius 2, r=2. That's kind of tough to grasp when looking at it for the first time. Counterpoint gave a triple integral to represent the sphere in the first octant, which is only an eighth of the...

Working it out the rest of the way for those who still don't fully understand: Initial Velocity, (Vi),=13 m/s Coefficient of Rolling Friction for Steel on Steel, (U),=0.002 Distance Traveled, (d),= unknown Final Velocity, (Vf),=0 Vf^2=Vi^2+2ad 0=169+2ad Now, F=ma=Umg where again...
