Servomotors are basically a high-performance type of electrical motor. They must be paired with a drive, which is also known as a motion controller. As a system, servos convert electricity into precisely controlled motion.
What are the 3 types of servos?
Different manufacturers might have small variances in how they list their servo sizes but they can usually be boiled down to three types: micro, standard and giant. These types specify both the physical size of the servo as well as the output torque and the power required to generate that torque.
