‘Off-the-shelf’ variable frequency drives

Paul Boughton

Bosch Rexroth has unveiled its new series of variable frequency drives for general automation, materials handling, pumps, fans and conveyors.
The EFC 3600 series, which will be available from The Inverter Drive Supermarket, marks Rexroth’s first foray into an ‘off-the-shelf’ product range.
Featuring both a Proportional Integral Derivative (PID) and a sequence control system, the EFC 3600 series 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 per cent, as well as high initial torque of up to 150 per cent, means that the new drives can be adapted for a wide range of uses including both 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.
Despite being highly functional, the easy to use removable control panel and compact design allows quick and easy installation and configuration.
