Detailed description of the invention
Below in conjunction with accompanying drawing, embodiments of the present invention are described in detail.As it is shown in figure 1, a kind of vacuum cleaner DC brushless motor, including shell 1, be fixedly installed stator 2 in the enclosure, rotor 3 that coaxial rotation is arranged in stator 2 and the fan 4 that rotor 3 is coaxially disposed, the fan housing 5 that is set in outside fan 4.Adopt the electric machine structure of internal rotor, the rotor needing to rotate in motor work process is made to have as far as possible little radius, the resistance being subject in rotation process is much smaller relative to the motor of external-rotor-type, improve the work efficiency of motor, higher rotating speed can be obtained under same voltage input condition.
Shell 1 rear end arranges air outlet 11, and fan housing 5 arranges air inlet 51.Fan housing 5 inwall is provided with spiral duct 52, fan 4 rotate the wind of generation, enters air channel along spiral duct 52 tangential direction, ramps up in air channel, improves the movement velocity of cooling air.Shell 1 front portion arranges cooling air port 11 so that the fan 4 being coaxially disposed with rotor 3 rotates the cooling air produced can enter shell 1 in cooled air port 11, and parts therein are carried out cooling.Cooling air port 11 includes the taper wind-guiding face 111 drawn in gradually along fan 4 to rotor 3 direction.The cooling air entering cooling air port 11 moves along taper wind-guiding face 111, moves closer to the rotating shaft of rotor 3 so that cooling air and rotor have maximum contact area；Taper wind-guiding face 111 makes the bore of cooling air port 11 be gradually reduced simultaneously, corresponding, the movement velocity of cold air strengthens gradually, substantially increases the effect of cooling.Being provided with wind deflector 6 between cooling air port 11 and fan 4, wind deflector 6 is provided with air guide hole 61, and air guide hole 61 is gradually reduced along its bore of fan 4 to cooling air port 11 direction.Described air guide hole 61 guides the direction of motion of cooling air so that it is concentrate towards the rotor direction motion needing cooling；Meanwhile, the bore of its described air guide hole 61 is gradually reduced, and improves the cooling air movement velocity entering cooling air port 11, improves cooling effect.Rotor shaft 31 arranges wind-guiding block 311 inside wind deflector 6, and wind-guiding 311 pieces has the inclined-plane 3111 parallel with taper wind-guiding face 111.Inclined-plane 3111 leads into the cooling wind direction rotating shaft 31 of shell 1 and draws close so that rotor 3 has the big contact area with cooling air as far as possible, improves cooling-down effect.
Stator 2 include the outer shroud 21 of circle, be arranged in outer shroud 21 three each other angle be the support 22 of 120 degree and around the coil windings 23 being located on support.The root of support 22 is fixing with outer shroud 21 to be connected, and the center of circle of outer shroud 21 is pointed in the end of support 22.The end of support 22 is provided with pole shoe 221, and pole shoe 221 end arranges cambered surface, the cambered surface place annulus of multiple supports 22 and outer shroud 21 concentric.The distance of cambered surface and rotor outer surface is 0.3-0.8mm.Experiments verify that, the pole shoe 221 of this structure can greatly reduce the commutation loss of brushless electric machine semiconductor components and devices, improves electric efficiency, thus improving rotor speed.
In order to prevent rotor 3 from running up in process, the magnetic part of rotor is departed from rotor 3 by the effect of centrifugal force, and rotor 3 adopts the single piece by injection moulding integrated molding by magnetic powder and plastics.Simultaneously, moreover it is possible to reduce the assembly in rotor 3 motor process, simplify the structure of rotor, rotate more stable.
