The textile industry is a field characterized by high speed, high precision, and continuous production, currently undergoing a comprehensive transformation towards intelligent and flexible manufacturing. Modern textile machinery, such as high-speed spinning, weaving, and digital printing, places extremely high demands on motion control systems. For example, in high-speed winding and twisting processes, spindles must maintain an extremely high and constant speed of tens of thousands of RPM for extended periods; any slight velocity fluctuation leads to a decline in yarn quality. In weaving and knitting, multi-axis (e.g., yarn feeding, jacquard, take-up) must achieve strict precision synchronization to ensure pattern accuracy. In digital printing and automatic cutting, the print carriage or cutting head requires smooth, high-speed reciprocating motion, dynamically synchronized with the fabric feed. Furthermore, the high-temperature, high-humidity, and lint/dust environments common in textile workshops pose severe challenges to the long-term reliability and protection rating of motors and drive systems. Therefore, high RPM, precision synchronization, high reliability, and high environmental tolerance have become the core metrics for motion control solutions in textile machinery.
AKT Product Solution
To address the textile industry’s stringent demands for high speed, synchronization, and reliability, AKT provides precision drive solutions centered on high-performance Brushless DC Motors (BLDC) and Hybrid Stepper Motors.
- High-Speed & Precision Synchronization Solution: For applications like high-speed spinning (e.g., rotor spinning), high-speed winding, twisting spindles, and the feeding wheels of high-speed knitting machines, our high-performance BLDC motor series (frame sizes from 42mm to 110mm) is the ideal choice. Optimized for low vibration and high speed, this series features extremely low torque ripple and excellent dynamic balance, achieving stable operation up to tens of thousands of RPM. Combined with AKT’s intelligent BLDC drivers (utilizing FOC algorithms and supporting EtherCAT/CANopen buses), they enable nano-second level synchronization between multiple axes and closed-loop control of constant yarn tension, fundamentally ensuring the high quality and consistency of textile products.
- High-Precision Positioning & Sequence Control Solution: In applications requiring high-precision timing and positioning, such as the carriage motion of digital printers, the yarn-changing grippers of automatic winders, and the needle selectors and yarn feeders of flat knitting machines, our Hybrid Stepper Motor series (NEMA 17, 23, 34) offers excellent cost-effectiveness. Our 0.9° high-resolution motors, paired with drivers featuring micro-stepping and S-curve smoothing algorithms, ensure the print carriage moves smoothly without vibration during high-speed reciprocation, achieving micron-level droplet placement control and guaranteeing the precise intervention of yarn feeders at the correct sequence.
- High-Torque & High-Reliability Solution: For heavy-load applications such as the “beat-up” mechanism of looms (requiring high instantaneous torque), the main drive of heavy-duty warp knitting machines, and the fabric transport rollers in dyeing and finishing equipment, we offer Closed-Loop Stepper Motor Systems and high-power BLDC motors with planetary gearboxes. The closed-loop stepper system (integrating an encoder) prevents step loss under high load impacts, ensuring weaving pattern accuracy. Our high-torque BLDC motors (e.g., 110mm, 130mm series) combined with low-backlash planetary gearboxes form an Integrated Power Unit (IPU) that provides powerful, controllable torque output, easily handling the high inertia and variable loads found in dyeing vats and similar equipment.
Engineering & Customization Capabilities
We deeply understand the harsh environment of textile workshops. AKT provides in-depth customization services. In addition to standard shaft, flange, and winding customizations, we focus on providing motor enclosures with high protection ratings (e.g., IP65) to resist the ingress of lint, dust, and moisture. We can also integrate electromagnetic brakes (for power-off protection), high-resolution encoders, and provide special surface treatments resistant to high temperatures and corrosion, ensuring long-term stable operation during 24/7 continuous production.
Typical Application Equipment Examples
- High-Speed Winding Machine: The grooved drum or yarn guide on a winding machine requires extremely high, constant speed (up to 20,000 RPM) and an exceptionally fast tension response. Our low-inertia, low-vibration BLDC motors (e.g., 57mm, 86mm series) are ideal for this. Their millisecond-level dynamic response, paired with a tension sensor, allows real-time speed adjustment to maintain constant yarn tension, ensuring perfect yarn package formation.
- Digital Inkjet Printing Machine: The printer’s carriage and the fabric feed roller must be precisely synchronized. We use high-resolution stepper motors (e.g., NEMA 23) to drive the carriage, ensuring precise droplet placement (high DPI) through precise micro-step control. Simultaneously, a closed-loop stepper or BLDC motor precisely controls the fabric feed roller, achieving perfect Print-Feed Synchronization.
- Rapier Loom: “Weft Insertion,” one of the loom’s core actions, is driven by the rapier. This application demands extremely high dynamic response and instantaneous torque. Our high-torque closed-loop stepper motors or BLDC motors (e.g., 86mm, 110mm series) provide the powerful instantaneous torque needed to drive the rapier or rapier wheel at high speed for precise weft insertion, while their high reliability ensures zero step loss under high-speed reciprocating impacts.
