Fan and electric motor

The impeller (8) has impeller blades (23) connected with a base body (19) on a bottom side. The blades form impeller tips (29) facing away from a bottom relative to an extension of the impeller in a direction of a rotational axis (y). The tips overlap the body, and/or the blades end with a distance...

Beschreibung
Zusammenfassung:	The impeller (8) has impeller blades (23) connected with a base body (19) on a bottom side. The blades form impeller tips (29) facing away from a bottom relative to an extension of the impeller in a direction of a rotational axis (y). The tips overlap the body, and/or the blades end with a distance to an edge lap of the body at the bottom side by forming a diffuser region (30). A radius of a maximum extension of the blades lies in a range between 1.5 to 0.6 times of a radius of a maximum extension of the base body in a top view. An independent claim is also included for an electric motor.
