Electromagnetic retarders for commercial vehicles
The FRENELSA retarder installed in any type of vehicle for transporting goods, passengers and others, improves its performance in terms of safety, economy, comfort and sustainability thanks to its frictionless operation.
Advantages
Chassis mounting
They are mounted between the transmission or gearbox and the differential of front engine vehicles (trucks and buses), between two pieces of drive-shaft.
These models cover a wide range of applications in industrial vehicles from 3 tons.
When assembling the retarder, the stator is fixed to the chassis with brackets and shockmounts, and the drive-shafts are fixed to the rotors.

Mounting on transmission or differential
It is mounted on vehicles where the distance between the transmission and the differential is so short that mounting the retarder between two transmission sections is not possible.
When assembling these retarders, the stator is fixed to the transmission or differential housing and the rotors are fixed, on one side to the output plate of the transmission or to the input plate of the differential, and on the opposite side to the drive-shafts.
