what motor driver for servo motor?

Question

In every tutorial I've come across concerning servo motors, no one mentions motor drivers. Instead, they show the servo getting power directly from the microcontroller. Yet, I understand that a lot of current sinks when the torque rises.

So, can I power the servo motor via a power transistor or a motor driver for DC motors, like L293? Or there are any other motor drivers dedicated for servo motors?

Thank you in advance.

EDIT:

Even though it was a general question. this is the servo I have in mind: https://www.sparkfun.com/products/11884

Answer 1

This is a hobby servo for remote controlled models. It has got its own motor driver on board, and a closed loop controller. It's self-contained. It only requires DC power and the control signal.
