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 better heat dissipation and better dynamic behaviour by filling heat-conducting material surrounding the wound

body. REO braking 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).
