An AC servo drive and an AC servo motor work in tandem to achieve precise control and efficient motion in various applications. The link between them is critical for the seamless functioning of a servo system. At the core of this link is the closed-loop control system, which comprises the servo drive and motor. The servo drive serves as the brain of the system, receiving commands and feedback signals. It converts the incoming electrical signals into the appropriate power output needed for the motor. This power is then transmitted to the AC servo motor.

The AC servo motor is responsible for translating electrical energy into mechanical motion. It consists of a rotor and a stator, where the stator is energized by the output from the servo drive. The interaction between the magnetic fields of the rotor and stator generates motion. The motor's rotor position and speed are constantly monitored by sensors, providing feedback to the servo drive.

The communication between the AC servo drive and motor is typically facilitated through a feedback loop. Encoders or resolvers on the motor provide position and speed information, allowing the drive to adjust the power supplied to the motor in real-time. This feedback mechanism enables the system to correct errors and discrepancies, ensuring accurate and precise control of the motor.

The link between the AC servo drive and motor is established through power and communication cables. These cables transmit the control signals from the drive to the motor and convey feedback information from the motor to the drive. Additionally, modern systems often utilize digital communication protocols like Pulse Width Modulation (PWM) or Serial Communication Interface (SCI) to enhance the speed and accuracy of data exchange between the drive and motor.
