摘要： A suction producing unit for a vacuum is constructed with a motor having an armature (21) on a vertical shaft (25) whose lower end is supported in a ball-type bearing unit 27 held in a tolerance ring 65. The upper end of the shaft is journalled in a bearing 26 that is held in a swivel support including a spring retainer ring 43. The latter is part of a subassembly which also includes the upper bearing (43) and an upper housing (28). The stator field piece (22) of the motor is clamped between the upper housing (28) and a lower housing (29) which supports the ball-type lower bearing unit (27). A pair of insulating sleeves (121, 123) on the lower end of the motor shaft (25) serve to properly space the armature (21), the lower bearing (27) and the fan blade (70). The latter (70) is mounted on the shaft (25) at its lower end by an insulating flanged cap nut (130) mounted on the lower threaded end (Figure 15) of the motor shaft (25).

摘要： A by-pass vacuum motor assembly wherein the motor cooling fan is positioned in an opening at the bottom of the motor band and immediately above a flat plate portion of the fan housing bracket. The flat plate portion functions as a plate diffuser, redirecting air drawn through the commutator end bracket and across the motor internals into a radial exhaust between a bottom portion of the band and a top portion of the fan end bracket. The invention also includes a brush holder clip passing through a vertical opening in the commutator end bracket and engaging a collar on the brush mechanism. The brush mechanism passes through a horizontal opening in the commutator end bracket which intersects with the vertical opening. Armature grounding is achieved by a disk maintainea in a recess in the commutator end bracket and urged by a spring against the bearing receiving the motor shaft The power wires to the motor are secured by a tab maintained opposite an opening in the commutator end bracket which is itself opposite an opening in the band. Power wires pass through the openings and over the tab, being crimped thereby.

摘要： A fan for a vacuum cleaner has a fan housing, a motor and an impeller. The fan housing has an inlet, an outlet, a scroll-shaped side wall, a back wall and a flat front wall. The impeller (24) has a hub and multiple blades (46). Said blades (46) have a leading edge (50) that is tapered upward, a top edge (52) that is tapered downward, and a trailing edge (54) that is tapered downward. Such tapering of the top edge (52) and trailing edge (54) provides less noise and better durability without diminishing air performance.

摘要： A quiet by-pass vacuum motor wherein a ring-like cavity is defined between inner and outer walls of the housing for a working air fan. Separating members divide the cavity into passageways which communicate with openings in the housing. A plate having a plurality of vanes thereon is received upon the separating members, the plate extending from the outer wall to a position short of the inner wall. A baffle plate is then received upon the vanes. Working air is exhausted over the baffle plate, between the vanes, over the plate and between the separating members and through the openings. The exhaust path greatly reduces the noise level of the vacuum motor.

摘要： A motor-fan unit for a wet pick-up type of vacuum cleaner comprising a fan-section (50) and a separately ventilated motor section (10). A motor-end bracket in the motor housing structure serves as a common end wall with the fan section and carries a bearing (40) for the common shaft (15) of the motor and fan. A baffle (38) carried by the motor-end bracket within the fan section has an apertured central portion (52), at least partly enclosing the bearing, to provide a passageway for high velocity air sealing the bearing from detergent-containing cleaning liquid entrained in working air drawn into the fan section and whereby said baffle portion (38) of said passageway (51) extends said passageway radially inwardly of the periphery of said support means and therebey locates said annular orifice (52) within said space between said bearing and the most closely adjacent fan (66) of said fan system.

摘要： The invention relates to a high-speed electric motor (2) with a rotor (3), a stator (4) and an impeller (6) fastened to a rotor shaft (5), wherein due to a diversion, the motor cool air fed through the impeller (6) flows partially through the motor (2) and partially externally on a substantially cylindrical motor housing (7). Diversion is achieved by a diffuser (45) working together with a fan casing (50), and the diffuser (45) has a diffuser plate (51) on which return blades (48) turned towards a motor space (46) are constructed. A substantially annular outlet (43) for conveying cool air externally on the motor housing (7) is associated with the diffuser (45). To provide an improved, high-speed electric motor of said type, it is proposed that the width (h3) of the outlet (43) is approximately 50 to 70 % of a vertical distance (h4) (when measured parallel to the rotor shaft (5)) of the diffuser plate (51) from the outlet (43).

摘要： A vacuum cleaner blower (1) with a blower wheel (7) and a motor (2) arranged for rotating the blower wheel (7) abuts its axis of symmetry (13), and a diffuser (8) extending radially beyond the outer periphery of the blower wheel (7), and wherein the diffuser (8) has guide surfaces (17, 18) which form diffusion flow passages (14) that define the flow direction for the air conveyed through the diffuser (8) from the blower wheel (7), said flow direction being anywhere in the diffuser flow passage (14) definable by velocity components in radial, axial and tangential directions, respectively, relative to the axis of rotation (13) of the blower (7). The diffuser flow passages (14) according to the invention formed by the guide surfaces (17, 18) being so provided that they convey the flow of air in such a manner that the velocity component of the flow in the axial direction relative to the velocity component of the flow in the radial direction is higher at the outlet opening of the diffuser flow (14) than at the inlet opening, makes it possible in case of given installation dimensions to design an efficient diffuser while simultaneously providing the blower wheel with a relatively large outer periphery.
