Electrical energy that is returned from a motor to the inverter for dynamic braking is consumed by resistors connected to DC intermediate circuits of inverters. Braking is controlling the rotating speed of the motor by converting the rotating energy into heat.

Dynamic braking resistors drain excess voltage and keep motors within safe tolerances thus slowing down or quickly stopping them. A key component of dynamic braking resistors are to dissipate the excess voltage as heat, so it is vital that only the highest quality components are used for them. Electrohm's resistors enable fast braking and limit any overheating by reducing the wear and tear of friction braking components.
