Abstract

1,090,255. Electric motors. NATIONAL UNION ELECTRIC CORPORATION. May 6, 1965 [May 15, 1964], No. 19252/65. Heading H2A. [Also in Divisions A4 and F1] In a motor-fan unit, for example in vacuum cleaner, the motor casing 29, Fig. 4, and the larger diameter fan casing 31 are connected together by tabs (81), Figs. 2 and 5 (not shown), and screws 80 to form an annular outlet- 8 for the fan 61. The fan discharges air through the annular outlet and slots 84 in the vacuum cleaner casing 11. The air passes over circumferential slots 94 in the motor casing 29 and thereby induces a cooling air flow through the motor casing, the cooling air being supplied through slots 93 and openings 92. A fan 90 increases the cooling air flow. Some of the cooling air discharges from the motor casing through an annular gap 50. The main air flow provides some external cooling of the motor casing. The motor casing comprises two parts 36, 37 having inwardly projecting indentations which locate the upper and lower ends of a stack of laminations 46 to position the latter when the parts 36, 37 are drawn towards each other by screws 39. Heat generated in the lower bearing 52 conducts to guide vanes 102 where it is absorbed by the main air flow, and heat from the upper bearing 51 conducts to the fan 90 where it is absorbed by the cooling air flow. The motor-fan unit is supported at its upper end by a seal ring 32 engaging the ends of ribs 33, and at its lower end by a seal ring 34 engaging a mounting ring 35. The seal rings 32, 34 arc preferably of sponge rubber.
