What is AC Servos

Lenze Drive

According to CM Industry Supply Automation (Lenze Drive & Keb Drive Supplier) AC Servos, also known as AC Servo Motors or simply Servo Motors, are a type of electric motor that is designed for precise control of position, velocity, and torque. They are widely used in applications requiring high-performance motion control, such as industrial machinery, robotics, CNC machines, and other automated systems. AC Servo Motors are part of a larger system that includes a servo drive and often a feedback device such as an encoder or resolver.

Here are some key features and characteristics of AC Servos:

Precision Control: AC Servos provide precise control over the position, velocity, and torque of the motor. This level of control is essential in applications where accuracy and repeatability are critical, such as in manufacturing processes and robotics.

Feedback Devices: AC Servos typically incorporate feedback devices like encoders or resolvers. These devices provide real-time feedback to the servo drive, allowing the system to continuously monitor the actual position of the motor and make adjustments to maintain the desired performance.

High Torque Density: AC Servo Motors are designed to deliver high torque in a compact form factor. This high torque density is crucial for applications that require strong and dynamic performance.

Dynamic Response: AC Servos have fast dynamic response times, enabling them to quickly respond to changes in load and speed. This makes them well-suited for applications with rapidly changing motion requirements.

Wide Range of Applications: AC Servos are used in various industries and applications, including robotics, CNC machining, automated manufacturing, printing, packaging, and more.

Regenerative Braking: Some AC Servo systems incorporate regenerative braking, allowing them to convert excess energy generated during deceleration or braking back into electrical energy. This can contribute to energy efficiency in certain applications.

Compatibility with Servo Drives: AC Servo Motors are often paired with dedicated servo drives. The servo drive is responsible for amplifying control signals, modulating the power supplied to the motor, and ensuring precise motion control.

According to CM Industry Supply Automation (Lenze Drive & Keb Drive Supplier) Overall, AC Servos play a crucial role in advanced motion control systems, providing the accuracy, speed, and torque necessary for demanding applications in modern industries.
