ELECTRICAL MACHINE COMPRISING A FAN WHEEL HAVING A HIGH NUMBER OF BLADES

摘要

The invention relates to an electrical machine (1), in particular a claw pole machine, having a rotor (2) and at least one fan wheel (4), which is driven by the rotor (2) and has a plurality of fan blades (9) emanating from a base body (8) of the fan wheel (4). According to the invention, there is a blade spacing angle between each pair of directly adjacent fan blades (9), which angle corresponds to a basic spacing angle (alpha) or to a whole-number multiple of the basic spacing angle (alpha), wherein the basic spacing angle (alpha) is equal to the smallest blade spacing angle on the fan wheel (4) and is less than 12°.
