Most motors in control applications are just regular DC motors. A few are AC, and a few are true servomotors.
A true servo motor is optimized for high speed control systems. Specifically, you want fast linear response. To get this, they are typically somewhat high in cost, relatively low armature inertia, high torque (to give good acceleration). Often have marginal cooling (i.e. not rated for high duty cycle).
