FXTYP7575YNF050

FXTYP7575YNF050 is a frequency converter for special application fields. It is mainly used for DC motor control, such as synchronous motor control, traction generator speed control, rolling-mill speed control and medium and low voltage variable frequency operation of many kinds of motors.

Application Field

The biggest application field of FXTYP7575YNF050 frequency converter is in paper and film industry. For many kinds of paper machine, the main motor needs to adopt frequency control to change the speed of the motor which drives the paper or film. Meanwhile, it can adjust the tightness of the raw material or the finished product by changing the speed of the roller of the paper machine. Moreover, it also can be applied in many kinds of printing, plastic machinery, wire and cable and chemical industry, etc.

Working Principle

The FXTYP7575YNF050 converts the input power into the corresponding output power through rectification,filter,inverter,etc.. The frequency converter modulates the modulation of the pulse width to achieve the output power of the corresponding frequency. The common medium and low voltage frequency conversion output power is usually below 500KW. In this set of frequency network, the voltage and frequency are converted to achieve the purpose of medium and low voltage frequency control. Firstly，FXTYP7575YNF050 converter is used to rectify and filter the input alternating current, and then the alternating current is converted into a DC voltage, and then a heavy-lifting circuit composed of thyristors is used to modulate the pulse for variable frequency operation.

In conclusion, the main application field of FXTYP7575YNF050 is in paper and film industry, and its working principle is to transform the input alternating current power into the corresponding variable frequency output power through rectification, filter, inverter and modulation.
