380V 3 phase dc motor 40kw inverter
Power range
Voltage : 1140-2300V Single-unit power : 75-630kW
Application area
Suitable for the high-end application area with big inertia load, potential load, high precision, fast response and etc.
Features of system structure
- Traditional 3 level PWM structure of neutral character for inverting
- Simple circuit structure with less component and higher reliability. Higher voltage output can be realized without serial connect of power components
- Output voltage wave form is more like sine wave. High harmonic of voltage is less
- dv/dt is smaller, no special requirements to motors' insulate performance
- Small size and low cost
Performance Features ..............(AC drive)(variable speed drive)(VSD)(frequency converter).............
- Function of vector control, V/F control switching, Choose freely according to the using requirement form the 4 mode: V/F control, V/F with PG, seedless sensor vector control, vector control with PG.
- Auto discern motor parameters, adapt fast to the load
- High rating torque output of open loop low speed. Speed control reaches to 100: 1
- Total torque control of close loop zero speed. Control range reaches to 1000: 1
- Advance auto adjusting function to make motor work in the best condition
- Energy saving control function makes motor work in best condition, with PID adjuster, total automated operation is realized.
- Sliding compensation makes motor work stable
- Internal automated torque compensation function makes motor work accurately.
- Torque control function makes motor work with constant torque
- Auto reset when malfunction
- LCD panel with user friendly interface, multiple parameters can be adjusted online and copied, convenient for use
- Minimal pollution to electric network, high efficiency
