How does the PWM drive technology of SHJ-A weft feeder improve product performance?

Principle and application of PWM drive technology
PWM drive technology adjusts the output power of the motor by changing the width of the pulse, thereby achieving precise control of the motor speed and torque. In the SHJ-A weft feeder, PWM technology is used to control the speed and tension of the yarn feeding motor. Through the pulse signal of high-speed switching, the PWM driver can quickly respond to the control command and realize real-time adjustment of the motor output.

Improve motor control accuracy
The PWM drive technology of the SHJ-A weft feeder can achieve precise control of the motor. By adjusting the duty cycle of the pulse signal, the equipment can accurately control the speed and output power of the motor. This high-precision control capability ensures that the weft yarn maintains constant tension and speed during the feeding process, avoiding problems such as yarn winding and breakage caused by speed fluctuations.

Improve energy efficiency
Another major advantage of PWM drive technology is its efficient energy utilization capability. In traditional motor control methods, adjusting the motor speed is often accompanied by a large amount of energy loss, while PWM technology greatly reduces the power consumption of the motor during operation through the rapid switching of pulse signals. SHJ-A weft feeder can minimize energy consumption while meeting the requirements of efficient yarn feeding through PWM drive technology.

Improve the response speed of the equipment
In textile production, the yarn feeding equipment needs to quickly adjust the yarn feeding speed and tension according to the actual needs of the production line. Due to its fast response characteristics, PWM drive technology enables the SHJ-A weft feeder to complete the speed and power adjustment within milliseconds.

Reduce mechanical loss and equipment maintenance
When traditional yarn feeding equipment frequently adjusts speed and tension, mechanical parts are prone to wear, resulting in increased maintenance costs for the equipment. PWM drive technology significantly reduces the wear rate of equipment parts by reducing mechanical impact on the motor. During the working process, the SHJ-A weft feeder controls the smooth start and stop of the motor through PWM, which effectively reduces mechanical wear.

Improve product consistency
The consistency of textile products is an important indicator for measuring production quality. PWM drive technology ensures that the weft feeding conditions of each batch of products are consistent through precise control of the yarn feeding motor. This consistency is not only reflected in the appearance and feel of the product, but also in the strength and durability of the fabric. The SHJ-A weft feeder uses PWM technology to ensure that every meter of yarn is fed strictly according to the set parameters, which greatly improves the consistency and quality stability of the product.

Adapting to diverse production needs
With the increasing variety of textiles, the adaptability of production equipment has become increasingly important. The PWM drive technology of the SHJ-A weft feeder enables the equipment to easily cope with different types of weft yarn and fabric production needs. Whether it is delicate high-count yarn or thick low-count yarn, PWM technology can achieve the best yarn feeding state by adjusting the motor output.
