摘要

The fan impeller 6 has a conical surface 7 facing an annular conical surface 4 defined by an open end of the alternator casing 1. The blades 8 of the impeller extend axially from the conical surface of the impeller and have aerofoil cross-sections. Impeller surface 7 and casing surface 4 are not parallel since conicity angle A is greater than conicity angle B.
