Are there combined motor-position feedback systems- in the 1-1.5 N-cm range? Something 2 steps up from a hobby servo, but with excellent repeatability from motor to motor.

I've been using a 40 oz-in servo motor for my application, but I've begun to notice that each servo reacts to a given pulsewidth differently- by up to 3-5 degrees difference between servos.

Therefore, I want to move up and use a step motor or gearhead or DC with integral position indicating. That is I do not want to add a rotary position indicator, I want to acquire a motor already combined with a rotary position device.

Thanks,
Ron

I would recommend that you check our motor and stage advisor. In there you will find several companies that make motors and many of those motors already come with encoder feedback attached. The advisor can be found in:
