No, but sort of. If you look up servo motors you will see in your case that it's a small DC motor and the 4 wires provide feedback to the motor controller. The feedback could consist of parameters like speed, angle, direction.

Thanks again I will have a look at servo motors and how they are controlled to see if it is practical to use them. With regard to the other motors which I think are stepper motors I have seen comments that a 5 wire stepper motor is not suitable and needs to be converted to 6 wire if possible by removing the common ground.

Re: Printer stepper motors
Hi,
Servo motors are very difficult to control. They need special, often quite expensive controllers and can be a real pain to set up properly.
I also wouldn't rely on old printer steppers too much. They are designed for relatively high speeds but have very low torque. Everything needs to run absolutely smooth or you'll loose steps.

Thank you for your advice, in particular your comments on the printer stepper motors. I have just been looking at a web site called allmotion who are offering controllers for both stepper and servo motors.
