When an electric motor works as a generator (electromotive brake), the braking resistor protects the machine from a voltage rise in the DC link. At the same time, the reduction of current leads to a speed reduction of the engine and helps to brake the machine. REO braking resistors achieve a better heat dissipation and better dynamic behavior by filling heat conducting material surrounding the wound body. REO resistors are short-circuit proof and self-extinguishing. They guarantee a high level of operational safety and are overload-proof in case of short-term loads for your applications (e.g. wind power engineering, railway engineering and automotive engineering).
You can use the following filter options to set the required specifications and display the appropriate products. The REO experts are happy to answer any questions you may have at any time.
