What is the unique application of FOC drive technology in SHJ-P Weft Feeder?

The unique application of FOC drive technology in SHJ-P Weft Feeder not only significantly improves the performance of the weft feeder, but also further consolidates its position in the field of textile machinery. Below, I will elaborate on the specific application of FOC drive technology in SHJ-P Weft Feeder and the advantages it brings.

First of all, as an advanced motor control strategy, the core idea of ​​FOC drive technology is to decompose the motor control problem into two sub-problems: magnetic field control and torque control. In SHJ-P Weft Feeder, FOC drive technology achieves precise control of the weft feeding process by precisely controlling the size and direction of the magnetic field and the torque output. This control strategy enables key parameters such as the tension, speed and position of the weft yarn to remain stable, thereby ensuring high efficiency and stability in the textile process.

Secondly, the application of FOC drive technology in SHJ-P Weft Feeder is also reflected in its efficient energy utilization. By independently controlling the magnetic field and torque, FOC drive technology can optimize the operating efficiency of the motor and reduce energy loss. This not only reduces the energy consumption cost in the textile process, but also conforms to the current green and environmentally friendly production concept.

In addition, FOC drive technology also gives SHJ-P Weft Feeder dynamic response capabilities. In the textile process, the feeding of weft yarns needs to respond quickly and accurately to various changes, such as yarn tension fluctuations, machine speed adjustments, etc. FOC drive technology can quickly respond to these changes by adjusting the magnetic field and torque in real time, ensuring the stability and continuity of weft feeding.

In specific implementation, FOC drive technology achieves precise control of the motor through two key steps: current conversion and current control. Current conversion converts the three-phase AC current of the motor into DC current on the magnetic field axis and torque axis, while current control adjusts the current on these two axes according to the magnetic field and torque to be controlled. This control strategy enables SHJ-P Weft Feeder to achieve precise control of the weft feeding process and ensure the smooth progress of the textile process.

The unique application of FOC drive technology in SHJ-P Weft Feeder not only improves the performance of the product, but also further consolidates its position in the field of textile machinery. By precisely controlling the magnetic field and torque, FOC drive technology enables the SHJ-P Weft Feeder to maintain efficient and stable operation during the weaving process, making an important contribution to the development of the textile industry.
