Braking resistors find new applications

Tag: Variable Resistor
Although the most common use for braking resistors is in motor drives, the devices are ideally suited to other industrial applications.
Design engineers across a wide spectrum of market sectors are benefiting from the diversity, flexibility and versatility of braking resistors from TT electronics Welwyn Components Welwyn's range of thick-film planar braking resistors on steel offer the ability to withstand high pulses and provide a compact footprint and a low profile They can be easily and economically adapted to demanding applications, particularly in industrial and defence markets.
The resistors are generally used for dumping energy from a motor when the speed is significantly slowed down.
In this instance, the motor behaves as a generator which then returns the energy to the circuit where it is dissipated as heat in the braking resistor.
An example of this application is found in a lift, where the smooth deceleration to a complete stop is achieved by braking the motor and this braking energy is subsequently lost as heat in the resistor.
Although the most common use for braking resistors is in motor drives, the resistors have proved to be ideally suited to other industrial applications including stairlifts, battery equipment, industrial welding, wind turbines and power generators.
Welwyn is also experiencing increased interest for the resistors from engineers in the avionics market, both civil and military.
The ongoing demand for the resistors, and proof of their versatility, demonstrates Welwyn's ongoing commitment in responding to market needs with innovative precision components which can be readily adapted across a wide range of market sectors to achieve customised niche applications.
