Product Introduction

A direct drive variable frequency drive with permanent magnet energy-saving motor solution specially built for water-jet and air-jet looms. It integrates the core technology of direct drive motors with a variable frequency speed regulation system, abandons traditional mechanical transmission structures such as pulleys and belts, takes the DC permanent magnet motor as the core, and is matched with exclusive frequency conversion control technology to realize efficient, energy-saving and precise control of the main drive of the loom. The motor has built-in practical functions such as speed regulation, fixed-angle start/stop, and slow jog, and is deeply adapted to Junhe's A2/A3/A4/A6 series electronic control systems, which greatly reduces kinetic energy loss, improves weaving efficiency and equipment stability, and provides an integrated solution for textile mills to achieve energy-saving transformation and capacity upgrading.

FAQ

Q1: Can this permanent magnet energy-saving motor really save electricity? What is the actual energy-saving effect?

A: It is truly energy-saving. The motor efficiency is 94%-95%, much higher than traditional asynchronous motors. The energy-saving rate of the whole system is ≥20%, close to 30% in some working conditions, and the annual energy cost saved per unit is about 3,000 yuan .

Q2: How long will it take to recover the invested cost after replacing this motor system?

A: Under normal production conditions, the investment payback period is about 1~2 years. The long-term benefit is more obvious due to electricity cost saving and maintenance cost reduction.

Q3: Is the installation and renovation troublesome? Do I need to change the original loom structure?

A: It is easy to install, fits the existing loom size, can directly replace the traditional motor without major changes to the body structure, and engineers can provide on-site debugging.

Q4: How about the operation stability? Will it affect fabric quality and production efficiency?

A: Stable operation. The direct drive structure has no belt slippage, precise and controllable speed, and smooth start and stop, which can effectively improve fabric flatness and weaving efficiency .

Q5: Is the failure rate of the motor and frequency converter high? Are they easy to break in the later stage?

A: The overall failure rate is low. There are no vulnerable mechanical parts such as belts. The core electronic control parts are verified by long-term working conditions with high durability and low maintenance cost.

Q6: How long is the warranty? How fast is the after-sales response when problems occur?

A: The whole machine has a 12-month warranty, and paid extension is available. 24-hour response and 48-hour on-site service in China; standby machines are provided for core faults, and maintenance/replacement takes ≤72 hours.

Q7: Can it be adapted to the looms and electronic control systems I am currently using?

A: It can be adapted to water-jet and air-jet looms, perfectly compatible with Junhe A2/A3/A4/A6 electronic control, and supports docking with mainstream brand loom electronic control systems.

Q8: Without belt drive, will there be strong impact during machine start and stop?

A: Adopts soft start, soft stop and fixed-angle start-stop control, with smooth operation without impact, reducing mechanical wear and protecting equipment and fabrics.

Q9: Can overseas customers buy it? How to ensure spare parts supply and technical support?

A: Products are exported to many overseas countries. There are maintenance stations overseas, supporting remote diagnosis, fast spare parts logistics and full-process technical guidance.

Q10: Can I test the prototype first before bulk purchase?

A: Sample machine testing is supported. The sample fee can be deducted from the subsequent bulk order payment. You can verify the energy-saving and operation effects on site before large-scale purchase.
