1. A motor for a ventilation device of a ventilation, air conditioning and/or heating system of a motor vehicle, comprising:
a base for mounting the motor on a support;
wherein the base comprises a surface that includes a depression, and
wherein an electronic board is fixed inside the depression,
a stator comprising a stator winding support and a stator winding;
a rotor comprising a shaft;
at least one bearing around the shaft of the rotor; and
a decoupling ring comprising an outer part secured to the mounting base, an inner part secured to the stator and forming at least one recess for respectively receiving the at least one bearing around the shaft of the rotor, and elastomeric material between the inner part and the outer part,
wherein the inner part of the decoupling ring is made of one piece with the stator winding support.
