Abstract
The utility model discloses a novel motor rotor structure. The novel motor rotor structure includes a discoid rotor body, a rotor seat and a rotor shaft; the center of the rotor body is provided with a through hole, the rotor seat is placed in the through hole and fixedly connected to the rotor body via a key; the rotor shaft is fixed to the rotor seat, the direction of the length of the rotor shaft is parallel with the axial direction of the through hole; and the rotor body is provided with a plurality of groove holes, a heat conductive block is embedded in each groove hole, and a heat dissipation fan is fixed to the rotor shaft at the rear side of the rotor body. By embedding the heat conductive blocks to the rotor body and adding the heat dissipation fan to the rotor shaft, the novel motor rotor structure utilizes cooperation of heat conductive blocks and the heat dissipation fan, heat dissipation speed is raised greatly and the cooling effect is excellent; and structure is simple, assembling difficulty is small, production cost is reduced, and performance is comparative stable.
Description
Technical field
The utility model relates to a kind of novel motor rotor construction.
Background technology
Motor comprises stator and rotor, and its rotor, as the rotating parts of motor, is the core component that motor outwards provides torque.Yet, after rotor long time running, being easy to occur superheating phenomenon, thereby causing motor performance to decline, shorten useful life, trace it to its cause, be exactly that rotor lacks cooling capacity in fact.
For this reason, also occurred that on the market some have the motor rotor construction of cooling capacity, as the application number Chinese patent that is 201220377078.1 discloses a kind of cooling structure of inner rotor motor, in this structure, in the armature spindle of rotor, there is thermal conductive cavity, in thermal conductive cavity, there is heat-conducting medium, one end of a heat conductive rod is stretched in thermal conductive cavity and contacted with heat-conducting medium, the other end of heat conductive rod is arranged in coolant runner, and the heat on armature spindle will be take heat conductive rod and be distributed as approach like this.Although existing this structure has improved the radiating rate of rotor, there is certain cooling capacity, but, its armature spindle wants opening to stretch in thermal conductive cavity and contact with heat-conducting medium by heat conductive rod on the one hand, again opening good seal is oozed out to prevent heat-conducting medium on the other hand, this is very high to seal request, thereby the fraction defective of this structure is higher, improved production cost, in addition, armature spindle is as the output of rotor, and its rigidity intensity is begun to speak to reduce in inside, thereby is difficult to guarantee the performance of rotor.
Therefore, be necessary for that people provide a kind of good cooling results, production cost is low and the rotor structure of stable performance.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of novel motor rotor construction, its good cooling results, and production cost is low, and stable performance.
For achieving the above object, the technical solution adopted in the utility model is: a kind of novel motor rotor construction, comprise a rotor body in the form of annular discs, one rotator seat and an armature spindle, the center of described rotor body is provided with through hole, described rotator seat is positioned at through hole and is connected and fixed by key and rotor body, described armature spindle is fixed on rotator seat, the length direction of armature spindle and the axially parallel of through hole, and, on described rotor body, offer several slotted eyes, in each slotted eye, be all equipped with heat-conducting block, on armature spindle, be fixed with a radiator fan that is positioned at rotor body rear side.
Wherein, on described rotor body, offer the heat dissipation wind channel that several run through rotor body front/rear end.
Wherein, described heat dissipation wind channel is helical form.
Wherein, described heat-conducting block is copper billet or silver bullion.
A kind of novel motor rotor construction that the utility model is set forth, its beneficial effect is: rotor structure of the present utility model by setting heat-conducting block on rotor body, and on armature spindle, install radiator fan additional, utilize coordinating of heat-conducting block and radiator fan, greatly improved radiating rate, cooling effect is splendid, and simple in structure, assembly difficulty is little, has reduced production cost, and performance is quite stable also.
Accompanying drawing explanation
Fig. 1 is configuration diagram of the present utility model.
Description of reference numerals:
10, rotor body; 11, heat-conducting block; 12, heat dissipation wind channel; 20, rotator seat; 30, armature spindle; 40, radiator fan.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.
Please refer to shown in Fig. 1, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of novel motor rotor construction, comprise a rotor body 10 in the form of annular discs, one rotator seat 20 and an armature spindle 30, described rotor body 10 center is provided with through hole, described rotator seat 20 is positioned at through hole and is connected and fixed by key and rotor body 10, described armature spindle 30 is fixed on rotator seat 20, the length direction of armature spindle 30 and the axially parallel of through hole, and, on described rotor body 10, offer several slotted eyes, in each slotted eye, be all equipped with heat-conducting block 11, on armature spindle 30, be fixed with a radiator fan 40 that is positioned at rotor body 10 rear sides.
For further improving radiating rate, on described rotor body 10, offer the heat dissipation wind channel 12 that several run through rotor body 10 front/rear ends.
Described heat dissipation wind channel 12 is helical form, can increase like this inner wall surface area of heat dissipation wind channel 12, is beneficial to heat radiation.
Described heat-conducting block 11 can adopt the metal derby that thermal conductance is good, such as copper billet or silver bullion etc., can certainly adopt the nonmetal block that thermal conductance is good, such as Graphene or diamond etc.
During use, radiator fan 40 is with armature spindle 30 run-in synchronisms, the heat of piling up on heat-conducting block 11 is dispelled fast, simultaneously, existence due to heat dissipation wind channel 12, the air flow energy that radiator fan 40 produces is taken away the heat on heat dissipation wind channel 12 inwalls, particularly heat dissipation wind channel 12 is helical form, increased the contact area of air-flow and heat dissipation wind channel 12 inwalls, the heat of rotor body 10 inside can be distributed faster, thereby make rotor structure cooling effect of the present utility model splendid, and it is simple in structure, assembly difficulty is little, reduced production cost, performance is quite stable also.
The above, it is only the utility model preferred embodiment, not technical scope of the present utility model is imposed any restrictions, therefore any trickle modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
