Servo gauge are typically AC synchronous brushless gauge with built-in positional feedback. Servo gauge are used in closed-loop motion control systems where angular position, speed and torque can be very accurately controlled. The rotor of a servo motor uses permanent magnets and can be infinitely positioned between magnetic poles on the stator by varying the voltage and current between windings.
Servo gauge are well suited to precision to applications where accurate control of motor speed, position and/or torque is required.
Servo gauge can be used in many different applications. The advantages listed above means that servo gauge are used more and more in industrial applications to replace conventional AC gauge and stepper gauge as well as hydraulic and pneumatic systems. There are many applications where servo gauge have an advantage.
