    Hello All, Is there some way to get a Dc gear motor to run at the same speed even under slightly different loads?

    Thanks

    There is - depends on the approach you choose, of which there are several - probably boils down to complexity / cost in the end according to your requirements.

    For example the motor control in the following link uses the motor back EMF to sense & control the speed under varying loads.
