3-phase frequency inverter / flange-mount / for the textile industry

 

    The Performance of JAC 580

 

                  Support the vector control for various motors.

  1.  Support the asynchronous motor and the vector control for an synchronous motor.
  2.  Support the vector control for permanent magnet synchronous motor without absolute position  feedbacks.
  3.  Support various encoders,differential encoder,open collector encoder and rotary encoder.

 

                   The newest non-speed sensor vector control 

  1.  The non-speed sensor vector control can do locked-rotor movement and it can output 150% rated  moment  of force at 0.5Hz.
  2.  The non-speed sensor vector control can reduce the sensitivity of motor parameter and improve the  current applicability.
  3.  It can be used for winding control,load distribution under various motors dragging one load and other  occasions.

 

                 Characteristics of high starting torque and superior  responsiveness

  1. 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.
  2. Without the vector control for sensor, the torque is
