Abstract
The invention proposes an arrangement for the mechanical interfacing of a micromotor of the MEMS type with a toothed wheel in which the micromotor is produced in the upper layer of a plate made of crystalline or amorphous material and comprises at least one actuator which drives a rotor in rotation, characterised in that a pinion, coaxial with the rotor and arranged above the rotor, is connected in rotation to the rotor by means of at least one pin which is received in an associated housing and in that the pinion meshes with the toothed wheel.
