China power inverter 7.5kw 380V
The Performance of JAC 580
Support the vector control for various motors.
- Support the asynchronous motor and the vector control for an synchronous motor.
- Support the vector control for permanent magnet synchronous motor without absolute position feedbacks.
- Support various encoders,differential encoder,open collector encoder and rotary encoder.
The newest non-speed sensor vector control
- The non-speed sensor vector control can do locked-rotor movement and it can output 150% rated moment of force at 0.5Hz.
- The non-speed sensor vector control can reduce the sensitivity of motor parameter and improve the current applicability.
- It can be used for winding control,load distribution under various motors dragging one load and other occasions.
Characteristics of high starting torque and superiorresponsiveness
- The 150% starting torque can be provided at 0.5Hz ( without the vector control for sensor) , while 180% torque at zero speed (with the vector control for sensor) can be provided at 0 Hz.
- Without the vector control for sensor, the torque is <20 ms. With the vector control for sensor, the torque is <5 ms
