What is a 3-Phase AC Servo Drive?
A 3-Phase AC Servo Drive is a high-performance servo drive powered by a three-phase AC power supply (typically 220V or 380V) for precise closed-loop control of the position, speed, and torque of AC servo motors.
Compared to single-phase servo drives, three-phase AC servo drives offer:
- Higher output power capability
- More stable current and torque control
- Better suitability for continuous operation and heavy-duty conditions
