ALPHA6200 Series Special AC Drive for Textile Machinery

ALPHA6200 series special AC drive for textile machinery is independently developed by ALPHA Company. ALPHA 6210/6210S jet loom special drive realizes adjustmentof motor rotation speed only by varying the output frequency, thus no longer needs belts switching or any change on equipment. The production efficiency can be increased by over 15%.

Technical Characteristics

Step-lessspeed regulation, easily and efficiently solve the difficulty of speedregulating on textile machinery

Save accessories and manpower for belt-changing and adjusting, highly raise production efficiency

Unique super start control speeds up the start and eliminates the original star-delta transformation device, saving the cost.

Self-contained JOG function makes jet loom jog operation faster and easier.

Self-contained MODBUS communication protocol can directly communicate with the control systemof jet loom thus eliminates the problem of complicated wiring.

Easy operation and maintenance which can be done by common workers.

Save energy by 5%-15% at low rotational speed.


The special AC drive is commonly used in textile machinery, air-jet looms, and more.
