Name: Permanent magnet synchronous controller
Model:LL-AT500Y series
Input voltage: Three-phase 380V 0.75KW ~ 450KW

Description:
1. Specially developed for driving permanent magnet synchronous motor, which can realize the high performance vector control of permanent magnet synchronous motor.
2. Can save more electricity than asynchronous frequency conversion
3. Adopt sensorless open-loop synchronous frequency conversion technology
4. Quick response, making the exhaust pressure more stable
5. The mechanical wear of the air compressor is smaller, the motor noise is reduced, and the life time is extended.
6. With excellent self-learning function, it can accurately learn stator resistance, D-axis inductance, Q-axis inductance

Application
Open-loop permanent magnet synchronous screw air compressor
