Abstract
1415372 Electric motor-fan ETRI-ETUDES TECHNIQUES ET REPRESENTATIONS INDUSTRIELLES 3 Jan 1973 [10 Feb 1972] 327/73 Heading H2A An electric motor-fan comprising (a) a casing 20,. Figs. 1 and 2, including four arms 22, Fig. 2, supporting an inner circular flange 25, Fig. 1, and (b) a motor housing 3 fixed to the inner flange of the casing by screws 26 and supporting a stator 2, stator windings 1, and a rotor R on a shaft 4, is characterized in that the motor housing 3 has a density at least twice that of the casing 20. This feature is said to reduce, by half, the vibrational noise output of the. fan when installed in the wall of a metal cabinet. As described the shaft 3 is rigidly moulded into. the motor housing 3, and an impeller 23 is sprung on to the rotor R.
