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 ...

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 ...

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 ...

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 ...

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 ...

AC drives or Variable frequency drives control speed, torque, acceleration, deceleration, and rotation direction of AC motors. AC drives save energy by tailoring the power delivered to meet the actual ...

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 ...

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 ...

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 ...

In answering this question, it may be easiest to begin with the term “servo drive” itself. If we start with the term “drive”, here’s what a drive does in a servo system. It basically takes an input ...
