China, as the world's largest manufacturing base, has rapidly emerged as a key supplier of AC servo amplifier solutions, offering competitive pricing, fast delivery, and continuously improving technical performance.
What is an AC Servo Amplifier?
An AC servo amplifier (also called a servo drive) is responsible for receiving control signals from a motion controller or PLC and precisely driving a servo motor in terms of speed, torque, and position.
Its performance directly affects system accuracy, stability, and energy efficiency.
Key evaluation parameters include:
- Response frequency & control bandwidth
- Current loop, speed loop, and position loop accuracy
- Encoder compatibility (incremental / absolute / multi-turn)
- Communication protocols (EtherCAT, CANopen, Modbus, Pulse/Analog)
- Thermal stability and overload capacity
