Description

Motor

Technical field

This utility model belongs to the structure of magneto resistance speed-regulating motor, is especially a kind of changing for radiator structure of motor Enter.

Background technology

The radiator structure of motor has a great impact to its temperature rise, directly affects the service life of motor.At present, Traditional magneto resistance speed-regulating motor uses the casing surface type of cooling, i.e., the heat for producing in motor passes through motor internal Air self-loopa is delivered to casing surface, and with afterbody from fan and extraneous air cooling casing surface.And motor interior It is divided into two cavitys, the position temperature rise near fan end is slightly lower, and the spot temperature away from fan is higher, and this structure is unfavorable for electricity Motivation Homogeneouslly-radiating.With market quality more and more higher, what this motor had been difficult to meet market and user will Ask.

The content of the invention

The purpose of this utility model is to provide a kind of motor of magneto resistance speed-regulating, improves hydronic efficiency, reduces Motor temperature.

For achieving the above object, this utility model employs technical scheme below：A kind of motor, including support, stator And rotor, axially disposed first current path on support, the two ends of the first current path are respectively communicated with the axial direction two of stator End, one end of rotor arrange blade fan housing, and blade fan housing pushes air-flow and circulates along gas channel.

In above-mentioned technical proposal, due to axially disposed first current path on support, the air-supply of blade fan housing in addition is made With, and the current path formed with reference to stator and rotor airgap, can by motor operation when the heat that produces in air flow Implement effective underground heat with support under driving to exchange, substantially increase the radiating efficiency of motor, especially the effect with Homogeneouslly-radiating Really, improve the temperature environment of motor running.

Specific embodiment

With reference to Fig. 1, a kind of motor, including support 10, stator 20 and rotor 30, it is characterised in that：Along axle on support 10 To the first current path 11 of arrangement, the two ends of the first current path 11 are respectively communicated with the axial two end faces of stator 20, rotor 30 one end arranges blade fan housing 40, and blade fan housing 40 pushes air-flow and circulates along gas channel.

Due to being provided with the first current path 11, and with reference to the certain composition of the air gap formed between stator 20 and rotor 30 Current path, the rotating shaft when motor works drive 40 synchronous axial system of blade fan housing and then push air-flow along gas channel recycle stream It is dynamic.Such scheme can will carry out effective heat exchange between the heat and support in motor chamber in time, make motor be in ideal Temperature environment under run.

Preferably, with reference to Fig. 1,4, the second of 30 iron core both ends of the surface of insertion rotor is offered on described rotor 30 Current path 31, one end of the second current path 31 are connected with the guide passage 41 on blade fan housing 40.

The preferred version for constituting the second current path 31 is on the iron core outer cylinder of rotor 30 to open up insertion both ends of the surface Groove constitutes the second current path 31, and the vallecular cavity section of groove is circular arc or U-shaped.

As shown in Figure 1, 2, support 10 includes inside and outside two-layer cylinder 12,13, arrange between inside and outside two-layer cylinder 12,13 every Plate 14, surrounds axially disposed bar shaped vestibule 15, two adjacent dividing plates 14 between inside and outside two-layer cylinder 12,13 and dividing plate 14 End baffle plate 16 is set forms through hole 121 that 12 barrel of insertion inner barrel is opened up on the inner barrel 12 of enclosed chamber and constitute the One current path 11, the first current path 11 arranged for interval in the circumferential scope of support 10.Using upper scheme, can improve and adopt Material usage is reduced while the intensity of support is made with stainless steel material, and with excellent heat exchange efficiency.

With reference to Fig. 1,3, blade fan housing 40 includes sleeve pipe 42, and the axial direction of sleeve pipe 42 is axially coincident with motor, sleeve pipe 42 it is outer Pipe end has extended radially outward ring-type flanging 43, and in sleeve pipe 42, pipe end is radially interior is extended with ring-type in-flanges 44, internal ring 45 is equipped with sleeve pipe 42 outside pipe end, the anchor ring of internal ring 45 is axially vertical with motor, internal ring 45 and ring-type flanging 43rd, blade 46 is provided between sleeve pipe 42, what composition radial direction, axle were connected between ring-type flanging 43, sleeve pipe 42 and blade 46 leads Logical circulation road 41.

Described internal ring 45 is concordant with the plate face of ring-type in-flanges 44 and is combined with the axial end of the side of rotor 30, institute Outer tube diameter of the diameter of bore of the internal ring 45 stated more than sleeve pipe 42, endoporus and the motor shaft of ring-type in-flanges 44 coincide, described Internal ring 45 is identical with the external diameter of ring-type flanging 43,46 circumferentially spaced arrangement of blade.

Internal ring 45, the plate face of ring-type in-flanges 44 can be allowed in such scheme evenly to fit to the axial end of rotor 30 On, play a part of fixed rotor iron core, while the axial port of guide passage 41 and the groove for constituting the second current path 31 Port is postponed linking, reduces flow resistance.

In the ventilating and cooling scheme that this utility model is provided, internal path has the second current path 31, stator 20 and rotor The current path that the air gap path that air gap between 30 is constituted is connected with the formation of the first current path 11, it is ensured that heat it is timely Exchange.
