A fan includes a hub configured to be driven by motor to rotate about a fan rotational axis, blades that protrude radially from the hub and a band that surrounds the rotational axis and connects the tips of the blades. The band includes structurally-reinforcing ribs that protrude from the hub-facing surface of the band. A rib is disposed between respective tips of each pair of adjacent blades. Each rib bridges a knit-line of the band, and has a circumferential dimension that is at least 40 percent of a distance between the respective tips of the adjacent blades.

The invention relates to an adjustment device () for a rotating body (), in particular a fan () of a cooling fan for a combustion engine, or a shaft () or a rotor () of an electric motor (), comprising a rotation axis (R), wherein a mass () that rotates around the rotation axis (R) can be dislocated relative to the rotation axis (R) by means of the adjustment device (). The invention further relates to a rotating body (), in particular a fan () of a cooler blower for a combustion engine, or a shaft () or a rotor () of an electric motor (), comprising an adjustment device () according to the invention.

The motor of an automotive cooling fan system is attached to a housing by either bayonet mount, screw mount, or axial-snap features on both motor and housing, as well as a cradle structure on the housing.

Mount for connecting automotive fan motor to housing

An external rotor motor is disclosed, which features a stator () and a rotor () surrounding the stator () while leaving an air gap. A damper () made of an elastic material is arranged on the outside of the rotor () in order to dampen resonant rises in airborne sound, which is emitted by the rotor of the external rotor motor and by an assembly coupled to it. In the case of a rotor () that is designed to be pot-shaped, the damper () is preferably embodied as a damping cap (), which surrounds the pot jacket () and at least partially covers the pot base () ().
