Variable speed drive range launced

12 June 2013

Bosch Rexroth has unveiled its new series of variable frequency drives for general automation, materials handling, pumps, fans and conveyors.

Better known for providing tailored solutions, the EFC 3600 series, which will be available from The Inverter Drive Supermarket, sees Rexroth venturing into an ‘off-the-shelf’ product range.

The new variable speed drive range features both a Proportional Integral Derivative (PID) and a sequence control system, and allows energy-efficient operation of equipment and machinery at their optimal operating point. The in-built control systems also enable load dependant adjustment of the voltage and frequency curve, extending motor service life.

A high intermittent overload capacity of up to 200%, as well as high initial torque of up to 150%, means that the drives can be adapted for a range of uses including heavy duty and energy-saving applications.

Initially designed for applications in the 370W to 4kW range, the EFC 3600 also features integrated brake choppers and mains filters, reducing the need for additional components.

Speaking about the launch, Bosch Rexroth Automation specialist, Paul Streatfield said: “The new EFC 3600 series marks the first time that we have entered the low-cost, high-volume drives and controls market. This has been made possible by advances in technology, which mean that we can now provide intelligent drives that can be adapted for a wide range of applications."
