Servo amplifier to control dc motor

[muh_j18]

hi,
sorry my English isn't perfect but please try to understand :
my teacher gave me a project in which i have to use a small dc motor,op amp,and a "servo amplifier" to control the rotation of the shaft of the motor, so can you tell me what is the servo amplifier? and how to use it to control the dc motor?

I may move this thread to the Homework Help section at some point, but because it's a project, I'll let it stay here for a bit.

Welcome to the PF, muh. Here is an initial reference on servo motors, and there are other links at the bottom of that webpage that should be of help as well:
