The servo motor converts the current and voltage that comes from the drive into mechanical motion. Most are rotary types but linear units are also available. There are many types of servo motors that can be used in servo applications, including brush, brushless, slotless, gear, rotary, and linear. Continuous torques ranging from just a few oz-in of torque to over 350 Lb-In (40 N-m). Sizes ranging from 0.375" to over 4" diameters. Applications include medical, semiconductor, moving webs, machine tools, packaging, factory automation, material handling, printing converting, food packaging, assembly lines, and many other demanding applications. The more demanding applications are ideal for brushless while more cost sensitive applications are ideal for brush servo motors.
