Motor with Gearbox and Differential

After the development of the Hi-Perm-Mag series, the Idea was to couple a transmission to it. The transmission consists in a system with self-locking differential engaged using fixed gears installed in a specially designed aluminum housing.

The transmission gears have ground teeth and have been treated to lower noise emissions and increase system efficiency.


Since the frame connection system is universal, the Hi-Perm-Mag DFT is also suitable for vehicles already in circulation and with different motorizations.

The auto-locking differential is equipped with increased gears and with the recovery of wear system that guarantee a long life.

The differential above mentioned has been developed by IET to permit swift maneuvering at low speeds with an increase in grip during cornering:

  • Better drive in curve;
  • Better torque/speed curve;
  • Swift maneuvering at low speed;
  • Consumption optimization.
