A servomotor is a motor that lets you control the exact position of the motor shaft as well as the speed and/or acceleration. Corresponding sensors and regulation technology are also used for this purpose. Previously, servomotors were auxiliary drives that were designed for use in machine tools. Incidentally, the servomotor gets its name from the Latin word "servus," meaning "server" in English. Servomotors consist of either an asynchronous motor, a synchronous motor, or a DC motor. The difference between the motors is therefore not in the drive principle itself, but only in their regulation capabilities.
