Brake Resisitor STBR
Brake resistors are of great importance in many electrically powered machines. They operate during start-up and are designed to protect the traction motor from damage. The brake resistor is installed to limit the current in the motor, which regulates the level of electrical activity, and thus protects the engine. This is regulated by what is known as a cruise switch, which is why brake resistors are sometimes referred to as rolling resistance. For generators, this form of resistor also provides the necessary protection from excessive voltages generated by induction. At the same time, the rotational speed is reduced by the current, which results in the vehicle slowing down. STBR - Braking resistors are suitable for use in lifting and landing gear, elevator drives, conveyors and drives to manipulators. So in all propulsion systems, which is required to controlling or regulating rapid speed changes and the excess energy, which is not consumed by the loads and losses of the machine.
