There are two types of motors that are typically used in CNC machinery: stepper and servo. Each of these motor types get both their power and direction/rotation information from a drive or amplifier. If you have spent any amount of time looking into the contrast of using a stepper as compared to a servo motor, you will find that there are distinct differences between the two. The basic operation of each type of these motors will be presented here for you to make your own determination regarding which type of motor would most benefit your system. After a discussion on each motor type, a contrast comparison of the two is presented. Hybrid configurations are also possible with the addition of an encoder to a stepper motor.
