Abstract

1,210,141. Axial-flow and centrifugal fans. PAPST-MOTOREN K.G. March 5, 1968 [March 16, 1967], No.10668/68. Heading F1C. [Also in Division H2] In a ventilation fan such as for cooling communications apparatus, comprising an electric motor having a stator 8, 9 and a rotor 1 comprising laminations 4 having exposed external surfaces defining an annular periphery, affixed directly to circumferentially spaced portions if the latter is a plurality of blades 13 of heat conducting material e.g. metal which withdraw heat from the rotor when the motor is energized. The blades may also exchange heat with one or both metal end rings 1a, 1b and may be integral, with, or resistance welded to, the laminations 4, considerable pressure being applied during the welding process. In Figs.3 and 4 (not shown), the blades are shaped as the vanes of a paddle wheel, and V-shaped. The fan may be of centrifugal type, Fig.3 (not shown).
