Application of FGI FD300 series low voltage frequency converter in printing machine

1.Overview：

The main motor of the customer was previously driven by DC motor, the motor has high power consumption and inconvenient maintenance, and needs to be replaced with carbon brush frequently, and the printing output is low. In order to save energy, we adopted the frequency conversion speed regulation technology, using FGI FD300 multi-function universal vector low voltage frequency inverter to transform it, improve the system function, make it easy to operate, easy to maintain, and make the high performance, high function of the printing press get full play, energy saving effect is obvious, has good application and promotion value.

In our daily life, how are the thick books, a large number of newspapers, beautifully bound calendars and so on these made? This is due to the printing press. Printing press is widely used in China's printing industry, and the main drive of the old model mostly uses DC motor. Because they are products from the 1960s and 1970s, the products are aging. Therefore, the frequency conversion transformation of the printing machine is imperative, and the first step of the transformation is to determine the model of the motor and the frequency inverter.

2.Implementation plans：

Determine the power of the motor and the frequency inverter according to the power and rotation speed of the original motor. The power of the original DC motor is 90 kW and the speed is 525-2100 r/min. Three ordinary asynchronous motors, model y160m-4, are used in this transformation. Adopt FD 300 series low voltage frequency inverter, rated power is 132kw, model FD 300-132g / 160P-4.

3. Application advantages

1, the low frequency torque is large, using FD 300 series low frequency stable operation.(The site user has used a brand of frequency inverter, the effect is not ideal after the purchase of easy energy FD 300 low voltage frequency inverter products).

2. The use of FD300 low voltage frequency inverter energy saving effect is obvious. After the site transformation, the energy saving is about 40 more than the traditional DC motor (customer measurement data).

3. Output increases significantly after FD300 low voltage frequency inverter is used, traditional machines require frequent maintenance, and the failure rate is high. The conversion transformation saves a lot of maintenance and maintenance time, and the machine is faster and the output is higher.
