Compact Vector Control BL5 Series Drives & Automation

BL52/BL50 AC VARIABLE FREQUENCY DRIVES

For over seven decades, Bharat Bijlee has been manufacturing and supplying energy efficient motors upto 1250kW. Since 2008, we also offer AC Variable Frequency Drives in partnership with KEB Automation, Germany.

In most industries that use motors for machinery there is a need for automation to achieve higher productivity, improve overall equipment efficiency and save energy. This is achieved by interfacing motors with AC Variable Frequency Drives that can vary the speed and torque of the motor to meet the application demand, besides reducing starting current kick and providing protection to the motor.

Many customers prefer combination package of motor and Variable Frequency Drive. It also ensures a single window for installation support, on-site service, repair, product training and provision of spares.

In order to meet growing demand of customers, we have introduced BBVERT BL52 and BL50 compact vector controlled AC VFDs that offer excellent reliability and superior performance. BL52 Drives are available from 0.4kW (1HP) to 110kW (150HP) in 3 phase/400V class range. For very low power applications BL50 series is available from 0.2kW (0.25HP) to 3.7kW (5HP) in 230V class (single phase/three phase) and from 0.4 kW (0.5HP) to 3.7kW (5HP) in 400 V class (three phase).

BL52 drives can be used for a variety of applications - fans, blowers, pumps, mixers, plastic machinery, conveyors, textile machinery, packaging machinery and more. Both BL52 and BL50 Drives are available through our sales partners and supported by our service centers across India.
