<DCServoMotor> schreef in bericht> What is the difference between a brush type "ordinary" DC motor and DC
Adding a form of feedback makes it servo. In the simplest form it could
be a potentiometer, like you find in the cheap RC servo's. The more
servo may use encoders, low inertia motors, to give both high torque at
low rpm's and great acceleration and deceleration, accurate start and stop
positions and what have you. Half the credits go to the control circuits

The distinction is that a servo has some sort of feedback, so you can
just tell it where to go and it can do so. Adding quadrature encoding
would help you along the way to making a servo, but unless you're
actually using it for feedback it wouldn't be a servo yet.
