Brake resistor

Inverter braking resistors or braking resistors are used in motion systems where the motor is controlled by a drive and help control the motor (charging resistance) through a process called dynamic braking. The function of the braking resistor is different in AC and DC motors. When the motor accelerates, electrical energy is converted to mechanical energy, and during deceleration, kinetic energy is converted to electrical energy by the motor, which must be dissipated. In order for the braking to be fast enough, this energy must be fed into a resistor and dissipated as heat. This action creates a brake in the system and protects the electrical system of the motor drive in terms of safety.
