Useful Motor/Torque Equations for EML2322L
... Our goal is to find a realistic range for Tm, the motor torque. As calculated above, Tw would be the maximum amount of torque the motor could transfer to the ground before the wheel begins to slip (ie Tm, max). Typically, we desire μw > μa, so the wheel does not slip/slide across the floor, but rat ...

L15 Electromagnetic induction and inductance
... Electric motors: The inverse of generators, current leads to motion. If the torque is constant, why doesn’t the loop get faster and faster? The rotating loop produces an induced EMF which opposes the original current, and the torque is reduced (a back EMF). So we get a balance between work done and ...
