AC servo systems have long been the workhorses of industrial automation, but it's time to start thinking of them as thoroughbreds. Thanks to ongoing advances in control algorithms and processing power ...

We have smartphones, smart watches, smart houses, and smart factories. It only makes sense that we have smart motors, right? Traditionally, a motor drive had one job: drive a motor. Now that’s not ...

AC motor drives are defined as amplifiers or frequency inverters that interface between a controller and an AC motor. They convert step and direction input from the controller to currents and voltages ...

The new Festo CMMT-ST servo drive starter kit offers a low-cost way to learn how to commission and size Festo’s multiprotocol family of servo drives that range from 300W DC up to 12kW AC. These kits ...

To some, motor speed control is somewhat of a mystical science, a science that causes motors and machines to sometimes operate in unexpected ways. Over 30 years ago, AC drives were considered "new ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

The series incorporates a new current loop design that achieves a frequency response of up to 3 kHz, and an auto-tuning function that performs optimal configurations ...

Physical size and weight provide the most visible evidence of the evolution of ac variable-frequency drives (VFDs) in the past 50 years. But, what's under the skin is even more dramatic for the ...

As manufacturing industry continues to replace manual processes with automated versions, servo motors are replacing pneumatic and hydraulic systems (Fig. 1). It’s resulted in a rapid increase in, and ...
