The utility model discloses a direct-coupled type high-speed centrifugal blower, which comprises a high-speed electronic motor and a centrifugal blower, wherein, the high-speed electronic motor comprises a motor housing; an electronic controller and a cooler are arranged outside the motor housing; a stator and a rotor are mounted in the motor housing; the stator comprises a stator iron core and a winding; the rotor comprises a motor rotating shaft and a magnetic steel which is arranged on the motor rotating shaft; the centrifugal blower comprises a blower housing, a blower main shaft and impellers; the motor rotating shaft is fixedly connected with the centrifugal blower; the stator iron core which is a slotless iron core is fixedly connected with the motor housing through a plurality of support parts; the motor housing, the support parts and the stator iron core are connected to form a cooling passage; and the cooling passage is communicated with the cooler. The high-speed centrifugal blower has the advantages that the design is reasonable; the structure is simple; the cumbersome gear speed change mechanism is omitted; and the weight is reduced, therefore, not only the miniaturization of devices is realized, but also the energy saving rate reaches 20 to 30 percent.
Description
Technical field
The utility model relates to a kind of electric blower, particularly a kind of straight connection type high-speed centrifugal blower that is directly driven by the high-velocity electrons motor.
Background technique
The high-speed fan of present domestic use, a kind of is to make the fan blade of blower fan reach high speed rotating by gear up mechanism, thereby makes high pressure positive blower; Another kind then is to form high pressure positive blower by multistage fan blade.It is big that the common drawback of above-mentioned two kinds of blower fans is not only volume, and use, maintenance cost height.
The model utility content
The purpose of this utility model is the deficiency that exists at prior art, and a kind of reasonable in design, simple in structure, straight connection type high-speed centrifugal blower of miniaturization but also good energy-conserving effect not only is provided.
The technical solution of the utility model is: a kind of straight connection type high-speed centrifugal blower is made of high-velocity electrons motor and centrifugal blower; Described high-velocity electrons motor comprises motor case, the outer installment of motor case has electronic controller and cooler, the inside of motor case is equipped with stator and rotor, and described stator is made of stator iron core and winding, and described rotor comprises machine shaft and the magnet steel that is arranged on the machine shaft; Described centrifugal blower comprises fan casing, blower fan main shaft and impeller, it is characterized in that: described machine shaft is fixedlyed connected with described centrifugal blower; Described stator iron core is the slotless iron core, and stator iron core is fixedlyed connected with motor case by a plurality of supporting elements; Described motor case, supporting element and stator iron core connect and compose the cooling channel, and the cooling channel is communicated with cooler.
The utility model compared with prior art has the following advantages:
The utility model is reasonable in design, simple in structure, owing to adopt the high-velocity electrons motor, improved the rotating speed of blower fan, because therefore the rotating speed adjustable of high-velocity electrons motor has saved heavy gear shift, has alleviated weight, not only realized the miniaturization of equipment, and the energy-conservation 20%-30% that reaches.
