Several types are used. The old standby, and one of the simplest to
drive, is the DC brush servo. This is probably the most well known
type of DC motor. There are also "DC brushless" motors, really
these are electronically-commutated AC Synchronous motors with
permanent magnet rotors. Finally, there are AC induction motors,
very similar to standard 3-phase AC motors.

The choice of motor is simply to match the servo amp. If you don't
already have a servo amp, then you can choose the motor most
easily available, unless the possibility of downtime causes a DC
brush motor to be undesirable.
