Abstract

1483128 Centrifugal fans UNIVERSAL CLIMB CO Ltd 8 Jan 1975 [29 Oct 1974 21 Nov 1974] 837/75 Heading F1C [Also in Division H2] An electric motor 60 has an end portion 14 of a housing 11 extending into an end of a multiblade cylindrical impeller 50a mounted on a shaft 31 of the motor, the housing 11 being generally too large to fit into the end of the impeller; the portion 14 partially accommodates rotor windings 34 wound on a core 32 on the shaft 31, and has at its outer end a bearing 16 for the shaft 31; the arrangement allows air to pass between the end of the impeller 50a and the portion 14 into the impeller whereby to cool the motor. In the arrangement seen, the other end portion 61, 63 of the housing 11 likewise extends into an end of a further impeller 50, the portion 61, 63 accommodating a brush assembly 40, 40a, 72, 72a and a commutator 35. The end portions of the housing may have an open structure to provide more effective cooling, e.g. as described with reference to Fig. 8 (not shown). Figs. 1-4 (not shown) relate to a double-impeller unit in which the corresponding motor housing extends significantly into only one impeller.
