PWM drive technology of SHJ-A weft feeder: dual advantages of improving performance and energy saving

What is PWM drive technology?

PWM (Pulse Width Modulation) pulse width modulation technology is a technology that controls the output power of the motor by adjusting the width of the pulse. In the SHJ-A weft feeder, PWM drive technology achieves precise control of the weft feeding process by accurately controlling the speed and torque of the motor. Compared with traditional speed regulation technology, PWM technology can not only respond to control instructions quickly, but also minimize energy waste, thereby improving the working efficiency and energy efficiency of the equipment.

How does PWM drive technology improve equipment performance?

1. Accurately control the feeding speed and tension

The SHJ-A weft feeder adopts PWM drive technology, which enables the equipment to accurately control the speed and output power of the motor during the feeding process. By adjusting the duty cycle of the pulse signal, the equipment can adjust the speed of the motor in real time to keep the tension of the weft stable. Traditional feeding equipment is often affected by mechanical friction and inertia, resulting in uneven weft feeding, breakage or jamming. PWM drive technology avoids these problems through precise adjustment, ensuring that the weft yarn can enter the loom stably and smoothly.

2. Improve motor response speed

In textile production, the yarn feeding equipment needs to respond quickly to various changes on the production line and adjust the yarn feeding speed and tension. PWM technology has the characteristics of high-speed response and can adjust the motor speed in a short time, so that the equipment can quickly adapt to changes in production needs.

3. Reduce energy consumption and improve energy utilization

Compared with traditional speed-controlled motors, PWM drive technology can use electrical energy more efficiently. In traditional equipment, adjusting the motor speed is usually accompanied by energy waste, while PWM technology achieves more efficient power regulation and reduces the loss of invalid energy by precisely controlling the width of the pulse.

4. Reduce mechanical wear and equipment maintenance

The SHJ-A weft yarn feeder adopts PWM drive technology, which effectively reduces the impact and friction of mechanical parts in the equipment by controlling the smooth start and stop of the motor. This enables the equipment to maintain a low wear rate during long-term operation, thereby reducing the occurrence of equipment failures and reducing maintenance costs. Traditional yarn feeding equipment often causes rapid wear of parts due to frequent mechanical friction, requiring frequent maintenance and replacement of parts. The application of PWM drive technology significantly extends the service life of the SHJ-A weft feeder and reduces the maintenance frequency and maintenance cost of the equipment.

5. Improve the consistency and stability of the production line

By accurately controlling the operating status of the motor, PWM drive technology helps the SHJ-A weft feeder maintain constant tension and feeding speed, thereby ensuring the consistency of the weft yarn during the production process. Whether producing fine yarn, coarse yarn or yarn of special materials, the equipment can automatically adjust the working parameters according to different production conditions to maintain stable output.

Comprehensive advantages of PWM drive technology
In general, the PWM drive technology of the SHJ-A weft feeder not only improves the operating accuracy of the equipment, but also brings many advantages:

High efficiency and energy saving: PWM technology reduces power waste, improves the energy efficiency of the equipment, and reduces operating costs.

Improve stability: By accurately controlling the motor output, the stability of the production process is maintained, and the phenomenon of weft breakage and shutdown is reduced.

Extend equipment life: Reduce wear of mechanical parts, improve equipment durability, and reduce maintenance frequency.
Strong adaptability: It can adapt to different production needs, and can quickly adjust the yarn feeding speed and tension to meet diversified production requirements.
