I took apart an RC car recently and found 2 sets of motors. The rear wheels (left) seem to run off an electric DC motor which is understandable.
The front wheels (right) I expected to be controlled by a servo motor because it can only make the front wheels face 3 directions (front, steer left, steer right) and no angles in between.
However, looking at the insides I can see that there are only 2 wires instead of 3. And the servo's that I've worked with before needed 3 wires for Vcc, ground and a control wire.
Could somebody confirm whether or not this is a servo? If not, what's the next best type of motor it could be? And how would I control it (PWM?, etc)
