A motor provides the torque necessary to keep a gear turning at
constant angular velocity, overcoming friction between the gear and
the axle.
The gear can be modeled as a disk, with mass 2 kg, and radius
rg = 0.2 m. The force of friction can be
modeled as a single force, acting at the outer edge of the axle, at
position ra = 0.02 meters, with force of
fk = 10 N.

The peak power of a PMDC motor is 1 W at 12 V. The stall torque at 12 V is 0.2 N-m. What is the torque constant for this motor?
Problem 47.- A dc motor develops 55 N-m of torque at a speed of 600 rad/s when12 volts are applied. It stalls out at this voltage with 100 N-m of torque. If the inertiaand damping of the armature are 7 kg-m^2 and 3 N-m-s/rad, respectively, find the transferfunction G(s) = θL(s)/Ea (s) of this motor, if it drives an inertia load of 105 kg-m^2 through a gear train, as shown in the Figure [Section: 2.8] Notice that the following torque-speed...
