What are servomotors and integrated servomotors? Summary for design engineers
Updated May 2018 by Lisa Eitel || Nailing down the features of a servomotor is a tricky exercise, but the hallmark of any servomotor is the presence of feedback and closed-loop control. Servomotors provide precise control of torque, speed or position using closed-loop feedback. They can also operate at zero speed while maintaining enough torque to maintain a […]
What is a Servo Controller? Summary for Motion Engineers
More specific types of controllers, such as servo controllers, are used to control servomotors. When dealing with servo systems, it’s important to note that definitions for servomotor, servo system, and servo controllers can differ widely throughout industry. When selecting a servo system for an application, it’s best to ask suppliers what exactly their offerings entail. […]
What are dc motors and how do definitions vary? Technical summary for engineers
Updated May 2019. || Dc motors are motion components that take electrical power in the form of direct current (or some manipulated form of direct current) and convert it into mechanical rotation. The motors do this through the use of magnetic fields that arise from the electric currents to spur rotation of a rotor fixed […]
