4. Servomotors

Servomotors are motors dedicated to servo functions and are normally designed for this purpose. Their main applications involve position control in a wide range of industrial sectors. They are necessarily associated with a servo device, and must be designed as a package including actuator, power supply and control. The focus here is on the specific aspects of small servomotors.

4.1 Specifications

Servomotors are generally required to deliver a sufficiently high level of torque in the shortest possible time, in order to achieve very high dynamics.

An example of the characteristics of a servomotor is shown in figure
