S6 Intelligent Servo Drives Drives & Automation

Bharat Bijlee is a leading Servo Drive manufacturer in India. Bharat Bijlee tied up with KEB as an exclusive sales and service partner in 2008; the partnership has evolved since then: it now also manufactures VFD and Servo drives under license.

Based on published data of 2014, the total market size of Low voltage AC drives & Servo solutions (Drive + Motor) in India is close to Rs. 2000 crores, of which 25% is contributed by Servo solutions. Both markets are growing @10-11% per annum. Many traditional VFD applications are migrating to Servo drive solutions, and it is expected that the Servo market will grow much faster in the near future.

There is high demand for Servo drive solutions in plastic injection moulding machines as awareness about this technology is high. KEB Servo drive is the most featured and robust product for injection moulding/extrusion machine, whose performance ensures consistent end plastic product. KEB is the world leader in plastic injection moulding machine market, enjoying around 30% market share.

KEB COMBIVERT S6 Intelligent Servo Drives

The COMBIVERT S6 servo system adds a compact, flexible and powerful drive module to the KEB product portfolio for highly dynamic servo applications. The optimally selected KEB components are the key to this successful drive concept. At the heart, the innovative S6 Servo drive is offered in an attractive book-style format and offers real-time performance.

The S6 drives can be matched with the robust DL3 servo motors which are available in five sizes. Additionally, the DL3 servo motors may be paired with planetary gearheads with low rotational backlash. You can now design the complete servo drive system that is best suited to your application. The package is made complete with pre-fabricated motor and encoder cables, which create the ideal conditions for easy installation, quick start-up and problem-free operation.
