The REOhm braking resistor can absorb and store energy for a short time thanks to a special winding method. The energy leads to a thermal change, a heating of the braking resistor. Thanks to a corresponding filling and compression, the thermal energy can be quickly transported to the surface during the pauses and released to the environment through contact with the cooling air. A heat sink increases the contact surface with the air through grooves and rods and accelerates the removal of heat. An even better cooling conduction is achieved by special heat-conducting liquids in series with REO liquid cooling.
Due to the rapid cooling of the winding body, whether by air or liquid, impulses in various intensities or durations can be continuously absorbed and do not lead to the destruction of the component. The REOhm braking resistors of the standard series are designed for a duty cycle of 5% -100% – smaller duty cycles are also possible on request.
