The purpose of a dynamic braking resistor (DBR) is to slow down or to quickly stop a motor by draining excess voltage and keeping it within safe tolerances. Our rheostatic resistors dissipate the excess voltage as heat. This can help to lower the wear and tear of friction braking components, enable faster braking and eliminate the risk of a runaway due to overheating.
When removed from a power supply, most DC motors will act as electrical generators due to their permanent magnets. If a resistor is then connected as a load, the energy produced by the rotational inertia of the DC motor will be dissipated by the resistor slowing down the motor. While AC motors do not have permanent magnets in their...
