If the torque was high enough and the wheel was free to move, would it be moving in the positive y or negative?
I'm going to assume the positive case. Off the top of my head the forces on the wheel I can think of are the tension in the rod, the torque from the motor, the friction, the weight and the normal. Am I missing anything?
Also, it sounds like the wheel is in static equilibrium, so I think the friction points somewhere in the southeast direction...

I hate physics.
