ABSTRACT:
A motorized reduction gear intended for functional equipment of a vehicle includes a rotor having with a rotor shaft bearing a commutator, a reduction gearbox containing a gearwheel engaged with a worm belonging to the shaft, and a magnetic ring attached to the commutator and mounted on the shaft to count the number of shaft rotations. The ring can be attached to the commutator in various ways, for example by overmolding the ring on the body such that the ring lies over virtually the entire length of the body. Hooks that retain the electrical connection of the rotor are attached to the magnetic ring. The attachment of the ring directly on the commutator, of which the ring forms an integral part, makes it possible to ensure reliable and lasting retention of the ring.
