Rotating parts called rotors are attached to the driveshaft. Separated by a narrow air gap, the stator is connected to the vehicle chassis. When electricity flows through the stator coils, electromagnetic fields with alternate polarities are created. As the rotors pass through these fields, eddy currents are generated which slow the rotors and thus slow the driveshaft. Any heat generated during braking is self-dissipated through the rotor vanes.

Traveling at 40 mph on a 6% gradient, the foundation brakes of a 19-ton, 4 X 2 vehicle reach approximately 750 degrees after only 150 seconds. Under panic stop conditions, the foundation brake temperatures can quickly climb to 2000 degrees.

Wherever there's a need for heavy "stop-and-go" brake applications, Telma Frictionless Braking systems have a solution. From buses and firefighting equipment to emergency vehicles, and refuse trucks, this break-through innovation immediately enhances safety and profitability.
