Features Of Sevro Inverter Screw Air Compressor
1. Small, fast action quick response, large overload capacity, wide speed range
2. The low-speed torque, low volatility, stable operation
3. Low noise, high efficiency
4.The rear end of the encoder feedback (optional) constitute a DC servo etc.
5. swing range, frequency adjustable
6. The angle of Induction motor is 3.6°1.8, the servo motor is highly Control accuracy, the angle is 0.036°, To achieve a closed-loop control of position, velocity and torque; To overcome the problem of out of step of Induction motor.
7. different performance:
The induction motor is Open-loop control, the highly Start Frequency or overload, it easy to Lost step or Stall, when stop, the high speed will be Overshoot phenomenon. Therefore, in order to ensure its control accuracy, Should handle the acceleration and deceleration problem.
The servo motor is Closed-loop control, The driver sampling directly to feedback signal of Motor encoder, Internal structure Position loop and Speed loop, It does not appear Lost step or Overshoot, There is more reliable control performance
8. The speed in response is different
It need 200 to 400 ms of Induction motor to accelerate from standstill to working speed. But for servo motor, it only takes several ms to accelerate speed to 3000 rpm , It can be used to control applications that require fast start-stop.
9. comfort: heat and noise significantly reduced.
Simple point that is: The induction motor, it will running for a while because of its own inertia after cut the power. But servo motors are stop quickly, start quickly, fast response
