An AC Servo Motor functions in tandem with a Digital Servo Drive in a closed-loop system. In this system, the AC Servo Motor has an encoder or resolver that constantly transmits feedback to the Digital Servo Drive regarding its position and speed. The Digital Servo Drive processes the feedback received from the AC Servo Motor in real-time and instantly adjusts the electrical signal to keep the AC Servo Motor at the desired position.
One of the notable characteristics of AC servo systems is that they have high torque output in proportion to their sizes. In addition, AC servos have the ability to provide high torque output at both low and high speeds. Due to this feature, AC servos can be considered highly versatile.
Furthermore, AC servos have a quick response time that can be used for smooth start/stop operations. Such characteristics make AC servos highly suitable for various applications in robotics, CNC machines, packaging machines, and automated assembly systems.
In addition to AC servos, digital servo drives have various features like auto-tuning, programmable motion parameters, fault detection, and communication with PLCs. Such features make digital servo drives highly suitable for modern automation systems. AC Servo Motors and Digital Servo Drives have played a critical role in improving productivity and achieving high-quality standards in today’s automation and manufacturing industries.
