REOHM Series 156

As soon as an electric machine works as a generator (electric motor brake), the braking resistor protects the machine from an excessive voltage increase in the intermediate circuit. REO braking resistors achieve better heat dissipation and better impulse loading by filling heat transport media in the vicinity of the wound body.


The BW 156 braking is designed for drives with frequency converters of small to medium output. Installation in and outside the control cabinet is possible.
