New Field Controller Provides Simplified, Cost-Effective Solution for DC Retrofit Applications

DC motor systems can be upgraded with a reduced number of external devices

MILWAUKEE, July 2, 2018 — The new Allen-Bradley PowerFlex DC field controller from Rockwell Automation enables customers to upgrade their DC motor application to a modern system, without the need for complex external devices. An up-to-date digital networked control system helps customers gather and leverage vital information throughout their enterprise.

The DC field controller provides three-phase, four-quadrant (reversing) DC motor or generator field control. The field controller can be used on its own or with a PowerFlex DC digital drive. In stand-alone mode, it provides power to a DC motor field with a fixed reference by using fixed I/O. The field controller can also control electromagnets and other non-motor loads.

“For DC retrofit applications that require motor reversing, the PowerFlex DC field controller helps eliminate the need for an additional armature bridge or a complex system of external devices, saving customers both time and money,” said Nancy Rivard, product manager for Rockwell Automation. “Having a single source for all automation equipment – including both AC and DC drives – also simplifies machine startup, operation and maintenance.”

The field controller offers output ratings from 17 amps to 575 amps and input of 200-volts and 500-volts. It enhances the capability of the PowerFlex DC drive family, designed for demanding stand-alone and coordinated drive system applications. The PowerFlex DC drive family is well suited for DC motor applications and retrofits up to 6,000 Hp or 4000 kW.

The PowerFlex DC family has core capabilities aligned with the PowerFlex AC family of drives, including seamless integration into a Logix-based environment, flexible feedback and communication options, as well as voltage settings designed to global standards.
