Initial thoughts for a system integrator might be to specify a servo motor. They are well known and can be very high quality, but while they might be the best choice for certain applications, there are some applications that do not need all of their capabilities. In these cases, a high-quality stepper motor could be the best choice.
When someone asks for a servo motor, they are asking for a motor that can deliver high speed, high torque, or high positioning accuracy.
