Au1250-500MGF is an intelligent frequency converter developed by AnHuaiDrive Technology. It can be used in various industries, such as metallurgy, petrochemical, papermaking, chemical, light industry, water conservancy, energy and so on. Au1250-500MGF has AC motor control and system vector control functions, which can realize high-performance control of induction motor, permanent magnet synchronous motor and other AC motors.

The working principle of Au1250-500MGF is based on the space vector modulation (SVM) control mode. The vector control system of this intelligent frequency converter consists of three main parts: the input side (including the AC input and DC input), the output side (including the AC output and DC output) and the control. The input power current and voltage of the frequency converter are firstly rectified to the DC link through the rectifier circuit. The DC link capacitor is connected to the three-level neutral-point-clamped (NPC) inverter circuit, and the motor is powered by three-phase output of the inverter. Then the inductance current is calculated by the SVM algorithm, and the voltage input to the motor is also calculated. Finally, the output torque and current of the motor are obtained, and the motor speed can be precisely controlled.

Au1250-500MGF has a wide range of application fields. It can be used in many production lines, such as textile, lifting, machine tool, wind power, water pump, chemical centrifugal, petrochemical, cement, rubber plastic packaging and other production equipment. It also has wide application in energy saving, light and small machine tools, oil station equipment, ventilation and air conditioning systems, hoists, heat pumps, etc. In addition, Au1250-500MGF has high efficient performance, long-term reliable stability and adjustable speed range.

In conclusion, Au1250-500MGF is an excellent intelligent frequency converter. It has wide application fields and reliable working principle. It can be widely used in various production lines and energy saving fields, making the production process more convenient and efficient.
