Therefore, it is mostly used on knitting machines or less demanding textile machinery. Controlled by industrial computer and programmable controller PLC. In most newly developed textile machinery products, the AC asynchronous motor variable frequency speed regulation device is applied almost without exception. For weaving machinery, there are sizing machines and warping machines. One type is the commonly used Y series AC asynchronous motor.

Large low speed loom reed suppliers, with swing frequency function, low electrode noise, has been well received by customers in the textile industry. Is a high-quality, high-level equipment. However, there is still a large gap compared with the international advanced level. 2. At the same time, the variable speed governor is used to control the speed of the 39 main motors to control the number of revolutions of the spindle, so that the spinning speed of the spun yarn changes in large, medium and small yarns to reduce the yarn breakage rate. Reduce power consumption and reduce costs Textile mills cannot do without air-conditioning equipment. Industrial control computer,

PLC and inverter are used to control 4 motors, which rotate the ingot wing, roller, simple tube and dragon ribs to lift and lower, respectively. Speed ​​range can reach 100: 1. 3. It is controlled by a PLC programmable controller or industrial computer, and then a multi-motor synchronous and coordinated operation is realized through a frequency converter. FA491 high-speed roving frame is a new type of roving frame developed in China in recent years.

Among them, PLC is used to control the operation of the whole machine and the parameters such as the moisture regain, the temperature of the drying room and the pulp tank, and the pressure of the pressure roller. When the air conditioner motor is controlled by a frequency converter, the power consumption is reduced, and the electricity expenditure is greatly saved. The tapered gear shifting device and forming device are removed, which simplifies the mechanism. Adopt speed sensorless vector control inverter. In order to increase the switching frequency of the inverter, a power insulated gate bipolar transistor (IGBT) is used instead of a general high-power tube (GTR).
