General use DC motors are not made to the same specs as DC servo motors, Servo motors usually have more poles, skewed rotors and are balanced for high rpm.
I have seen all types of motors that were Treadmill duty and all appear to be less than the normal manufacturers specs.
One I saw was a Baldor and had servo motor - Treadmill duty on the label. On inspection, the pole count appeared to be much lower than the regular Baldor servo.
I would be more inclined to get high quality servo's off ebay if you have limited budget.
