I have some servos with bad electronics. I'm in the process of converting them into geared motors by removing the electronics and the pin that limits the servos to 180 degrees. I found out that two servos also have bad motors inside them. Is it possible to replace the bad motors with new ones? I searched the Internet and I think that I can't find the right size of motor or I have to buy at least 100 motors from a company in China. The code on the motor is 1723RE-19120. It is about 17mm in diameter and about 27mm in length.

Unless there is something special about the broken servo, probably easier and cheaper to just get a new servo and modify if needed.

Would it not depend on how the electronics was broken ?

If the position feedback potentiometer was broken,  you could remove it and convert to a motor.    But you
would need the rest of the electronics to be working  for the PWM input to work, I would have thought.

A basic geared motor has two power wires with no electronics.

I visited Hobby King's website but they list torque in kg-cm only. They don't list torque in oz-in. Any suggestions?

I am confused about geared motors that I can buy in stores such as http://www.robotshop.com/spur-gearmotors.html. I thought that geared motors are more powerful than servos.
