What is the Difference Between VFD and Servo Drives?
Servo systems are now well-known for their use in CNC machining, robotics, and factory automation. The servo technology is further expanded with the manufacturing of servo drives, used for powering electric servomechanisms. Despite being an excellent option for industry use, we also have these VFDs (Variable-Frequency Drives) which tend to be used a lot as an alternative for servo drives, given their energy-saving potential. Since both of these are widely used in industry and manufacturing processes, it’s important to point out some of the differences between them and in which situations is one better than the other. To do that, we’ll first need to see what are VFDs and servo drives and then compare the crucial differences. A servo drive is an integral part of a servo system that consists of a motor, a controller, a feedback device, and of course – a servo drive. Simply put, a servo drive is a part of the servo system that receives a particular command from a control system, amplifies...
