Abstract
A cup () of a external rotor with symmetry of revolution about the axis comprises: a first cylindrical portion () which is radially internal, a second cylindrical portion () which is radially external and a third portion () between the two cylindrical portions (). When viewed in cross-section, the third portion () extends between two points (P, P) which define a straight line which forms, with the axis of the rotor cup (), an angle (a) of between 65° and 80°. The ratio between the distance (R-P, R-p) between the first point (P, P) which is radially internal or radially external, respectively, and the axis of symmetry of the rotor cup (), on the one hand, and the radius (R) of the second cylindrical portion (), on the other hand, is between 0.04 and 0.32 or between 0.65 and 1.0, respectively.
