If your motor's peak torque is 200Nm, and your rod is 10m long, the force you'll be able to apply from the end of the rod will be 20N. Get it? This wouldn't be enough to pull the skin off a decent rice pudding, let alone raise a wing. Think of trying to open a really heavy door by pushing it right next to the hinge.
However, the motor's peak torque will be at its rated speed, ie when it's spinning. Connecting your motor directly to the wing, and expecting it to oscillate is just not going to happen. This isn't what motors do.
