An electric motor 24 is disposed inside the cylindrical casing 12, and its commutation is performed electronically. The electric motor 24 includes a stator 26 having stator coils 28 arranged on a stator plate 30 . The entire stator is held within the casing 12 (the type of holding is not shown). Stator 2
A bearing 32 is attached to 6, and a rotor shaft 34 is supported in this bearing, and this rotor shaft is also attached to the electric motor 24. The rotor shaft 34 has one end 3
6 protrudes from the bearing 32. A rotor 38 is fixed to the other end of the rotor shaft 34 so as to be relatively unrotatable.
The rotor is made of a magnetic material bonded to plastic, preferably plastoferrite. Rotor 3
8 is magnetized in a known manner so that it acts as a permanent magnet. In this electric motor 24, the stator coil 28 is arranged in line with the rotor 38 in the axial direction of the rotor shaft 34. The rotor 38, as can be seen in FIG. 2, has a generally disk-shaped body 40, which is provided with a central extension 44 on its end face 42 facing away from the stator 26.

A central concave portion 48 is provided on the other end surface 46 of the disc-shaped main body 40 facing the stator 26 . The terminal end of the bearing 32 is curved within the recessed portion 48 (see FIG. 1). The rotor shaft 34 projects from the rotor body 40 from its end 36 through a central recess 48 . The body 40 is provided with a plurality of blades 50 on one end face 42, so that the rotor 38 also forms a blower impeller 52 associated with the blower. In short, the blades 50 are arranged on the end surface 42 on which the central additional portion 44'e is provided. The blades 50 extend in the axial direction of the rotor shaft 34. As can be seen from FIG. 3, the blades are curved in the longitudinal direction, and end without reaching the central additional portion 44 as a starting point on the outer circumferential surface 54-e of the rotor 38.

An electronic rectifier associated with the electric motor 24 is arranged in an extension 58 of the casing 12. During operation of the blower, air is sucked in from within the passenger compartment of the automobile, as indicated by arrow 60 in FIG. The air then rubs against the sensor 56, 4 so that the sensor 56 always reacts quickly. This air is transferred to the outlet 22 by a blower as shown by arrow 62.
It is discharged from.
