  • What is a Eddy Current Brake?

The Eddy Current Brake is an auxiliary braking system that improves the safety on the road and provides savings on the service brakes.

The KLAM retarder technology is based in the Foucault’s Law (Eddy Current Brake) and its well know brake effect. Basically, it’s a stator with coils (fix part) and self-ventilated rotors (moving part). When an electric current is applied to the stator, a field of magnetic force lines is produced, penetrating the rotors and creating the Foucault currents (resulting in a force that opposes the spinning rotors). The force brakes the vehicle without friction or wear, and the absorbed energy (Heat) is dissipated into the atmosphere by means of the spinning rotors.

Different from other braking systems such as the engine brake or the integrated hydraulic brake, the Eddy Current brake can be installed in a wide range of commercial or industrial vehicle, no matter if its new or pre-owned. Depending on the type of chassis and available space, the installation can be done in the driveline, on a transmission or on a rear axle. In addition, due to its modular construction, the KLAM retarder does not require an extensive maintance program, only a periotic inspection to assure an average life cycle of 15 years.

Beneficits
advantage

Savings

  • Up to 7X increase in brake life (Foundation Brakes).
  • 20% in rim.
  • 2% in fuel.
  • Travel times are greatly reduced.
  • Reduction in vehicle down time.
  • Reduced maintenance cost.

Safety

  • Up to 85% of braking is handled by ElectroMagnetic Brake Retarder. Brake shoes stay cool and greatly reduce risk of brake fade.
  • Stopping distance is reduced by half.

Enviromentally
safe

  • Complete absence of friction.
  • No friction. No maintenance.
  • Participates actively in the reduction of greenhouse emissions.

Study made by the University of Utah (USA) comparing the number of braking actions versus retarding value and service brakes use.

This confirms that the electromagnetic brake is the best system to save in service brakes and it’s more effective compared with hydraulic systems or engine brakes.

The multiple tests made show that installing a KLAM retarder can extend the service brake life up to 7 times.

The braking distance in any type of vehicle (commercial or industrial) is reduced to almost half the trajectory if the vehicle uses a KLAM Eddy Current Brake.

WHY KLAM?

Due to our 59 years of experience and the continuous R&D innovations, we have developed the KLAM retarder to produce the highest rated torque capabilities of all the electric brake manufacturers in the market. We offer retarders with 16, 8 and even 6 coils and are applicable to the driveline, gear box or rear axle. We offer, as well, competitive dimensions, weight and electrical consumptions.

The KLAM Eddy Current Brake is designed and manufactured with the most demanding standards and homologations, making our product efficient, safe and long-lasting. Due to the quality of materials and its modular construction, maintenance is not required.

With the cooperation of our subsidiary company, AM LIGHTING, (experts in the design and production of lighting systems and electronic components) we are able to design and produce all the control systems that guarantee the compatibility between the Eddy Current Brake and the vehicle.

Because of all the above and our customer care, flexibility, adaptability and promptness in solving problems, KLAM is considered number one in the customer´s mind.
