Embodiment
Now will be at length with reference to the preferred embodiments of the present invention, the example illustrates in the accompanying drawings.
As shown in Figures 1 and 2, outer rotor-type motor according to the present invention comprises the following cover 10 with inner space; Be coupled to down cover 10 and the sealing upward cover 20 of the inner space of cover 10 down; The stator of installing regularly in the inner space of covering 10 down 30; Placed the lip-deep rotor 40 of exterior circumferential of stator 30 with rotatable mode; Thereby rotating shaft 50 with the center transmission revolving force that is coupled to rotor 40.
Under cover 10 and so formed, make its basal surface to be closed, perhaps make it possible to utilize the cover plate (not shown) to cover the opening of basal surface.Thereby cover plate is formed the opening that dish type integrally covers basal surface, covers this opening individually thereby perhaps be formed fan-shaped each fan that utilizes.
As shown in Fig. 3 and Fig. 4, following cover 10 is formed the bowl-type with certain depth, and on its exterior circumferential surface, is integrally formed into a plurality of carriages 11 that are used for fixing outer rotor-type motor with the angle intervals of 120 degree.Be formed for connecting the axle supported hole 12 of rotating shaft 50 with rotatable mode in the center of covering 10 down.Be used for along the axle support protrusion 13 of radial direction supporting rotating shaft 50 outstanding with certain altitude from the periphery of axle supported hole 12 along the direction of axle.The stator mounting boss 14 that is used to install the stator core 31 of stator 30 is formed on crown of roll and plays 13 exterior bottom surface place.Being used to strengthen down, the going up of intensity of cover 10 strengthens rib 15 is formed on stator mounting boss 14 along the radial direction that plays 13 towards crown of roll inner peripheral surface.
Form alignment recesses (perhaps alignment bumps) 14a at stator mounting boss 14 places; Alignment recesses (perhaps alignment bumps) 14a is used to insert the alignment bumps or the alignment recesses (not shown) of stator 30, confirms the position that when connecting stator 30, stator 30 will be installed thus.Be formed for the stator fixing hole 14b of fixed stator 30 at a part place of stator mounting boss.
As shown in Fig. 3, downward enhancing rib 16 along radial direction be formed on crown of roll rise 13 on the exterior circumferential surface of covering 10 lower surface down.Bottom surface covering 10 down forms the osculum 17 of discharging condensed water through it.A plurality of fin 10a are formed on down on the exterior circumferential surface of cover 10 along radial direction.
Preferably, osculum 17 be formed on down cover 10 inner space, by each separate part place of last enhancing rib 15, thereby discharge condensed water apace.
As shown in Fig. 5 and Fig. 6, a plurality of lining installing holes 19 are formed on down an edge of cover 10, and a plurality of linings 61 of lead-in wire that are used to pass lead-in wire and the hole sensor of electric connector are coupled to lining installing hole 19.
Lining installing hole 19 is so formed, and makes contact can be interconnected on two surfaces at the edge of cover 10 down.Lining 61 is inserted in the surface, and utilizes blind patch 62 to cover another surface with sealing means.
As shown in fig. 5, be used to utilize bolt will play that cover 10 and last cover 20 be coupled to each other a plurality of connect protruding 18 and 22 be formed on down the opening of the surperficial and last cover 20 of the exterior circumferential of covering 10 opening respectively the exterior circumferential surface.One that connects in protruding 18 and 22 (in the drawings for connecting protruding 18) is provided with bolt head attachment recess or nut attachment recess, and this bolt head attachment recess or nut attachment recess have the shape identical with the angular shape of bolt head or nut and recessed with inserting bolt head or nut.
As shown in Figures 1 and 2; Last cover 20 forms the hat with certain depth; And the axle that is used to be received in the coupling part between rotor 40 and the rotating shaft 50 supports recess 21 and outwards protrudes in the central portion office of last cover 20, thereby reduces the size of outer rotor-type motor.The connection protruding 22 that engages with the connection protruding 18 of covering 10 down is formed on the edge of cover 20.The fin (not shown) can be formed on the exterior circumferential surface of cover 20.Preferably, along radial direction fin is set, strengthens radiating effect thus like angle intervals covering in 10 down with the 3-15 degree.
As shown in Figures 1 and 2, thus stator 30 comprises that having annular forms stator core 31, the coil windings (winding coil) 32 of on the 31b of tooth portion of stator core 31, twining of magnetic circuit and place the insulator 33 between stator core 31 and the coil windings 32.
Thereby stator core 31 constitutes by having the 31a of yoke portion and a plurality of tooth 31b of portion that annular forms magnetic circuit, thus the 31b of tooth portion winding around winding 32 above that on the exterior circumferential surface that radially places the 31a of yoke portion.
As shown in Figures 1 and 2, rotor 40 is made up of swivel plate 41 and a plurality of magnets 42, and this swivel plate 41 is connected to the upper end of rotating shaft 50; These a plurality of magnets 42 place with certain air gap along circumferential direction that thereby the N utmost point and the S utmost point can alternately be provided with each other on the exterior circumferential surface of stator 30, and are fixed to the inner peripheral surface of swivel plate 41.
Preferably, magnet 42 is so put, and makes its height to align with the height of stator 30, thereby strengthens the efficient of outer rotor-type motor.
To the operation according to outer rotor-type motor of the present invention be described.
When supplying power to the coil windings 32 of stator 30, rotor 40 rotates apace.The revolving force of rotor 40 is delivered to the blower fan of the end that is coupled to rotating shaft 50 through rotating shaft 50, rotates blower fan thus.
When the rotor 40 of outer rotor-type motor rotates apace, produce suction.In view of the above, when when the installation of sandy area has the outdoor unit of outer rotor-type motor, sand possibly introduced in the outer cover by the suction of rotor 40.Yet, have encapsulated type because following cover 10 forms with last cover 20, so prevented to be inhaled in the outer rotor-type motor such as the foreign matter of sand.In view of the above, prevented to make outer rotor-type motor impaired owing to foreign matter is inhaled in the air gap between stator 30 and rotor 40.
Because the outer cover of outer rotor-type motor seals,, and therefore can reduce the function of outer rotor-type motor so the heat of high temperature that produces from the inner stator 30 of outer cover is not easy to outside heat radiation.Yet stator 30 directly is attached to down cover 10, and the heat-conducting block (heat block) 61 that perhaps is attached to stator 30 is attached to down cover 10, and a plurality of fin 10a is formed on down on the exterior circumferential surface of cover 10 and last cover 20.In view of the above, the heat that produces from stator 30 outwards distributes apace, prevents that thus the function of outer rotor-type motor from reducing.
And then, outwards emit through osculum 17 from the inner condensed water that produces of outer rotor-type motor, prevent thus owing to damaging outer rotor-type motor at the inner wet steam of outer rotor-type motor.
In addition, because cover 10 is provided with the carriage 11 that is used for fixing outer rotor-type motor with being integral down, thus can simplify the assembling process of outer rotor-type motor, thus manufacturing cost reduced.
And, cover down 10 connection protruding 18 or on protruding 22 places of connection of cover 20 form the bolt head attachment recess or the nut that have corresponding to the shape of bolt head or nut shape and insert recess 18a.As a result, can will play cover 10 and last cover 20 to assemble each other with being more prone to, thereby reduce manufacturing cost.
