Description
Technical field
The present invention relates to asynchronous traction motor stator structure, specifically a kind of asynchronous traction motor stator for strengthening vibration resistance
Structure.
Background technology
Asynchronous traction motor is the nucleus equipment of High-power AC drives locomotive.Under prior art conditions, asynchronous traction
Motor causes it that various failures easily occur in operation because its stator structure is limited, and is specifically described as follows：It is as shown in figure 1, existing
There is asynchronous traction motor stator structure to include stator core 1, the threephase stator winding being set around in stator core 1, be arranged at and determine
Three polyester felts that three cables 2 and pressure-sensitive felt pan 3, the pad of 1 end of sub- iron core are located between three cables 2 and stator core 1
Pad 4；Wherein, three piece end lead-out wires 8 of the three head end lead-out wires 7 of threephase stator winding respectively with threephase stator winding are carried out
Three hanging pads are formed after once welding, end of three hanging pads again respectively with three cables 2 carries out two
Secondary welding.Practice have shown that there are the following problems for above-mentioned asynchronous traction motor stator structure：First, locomotive can produce in operation
Prolonged vibration, the vibration can be delivered to hanging pad, cause hanging pad to be vibrated for a long time, thus
Cause pad that vibrating fatigue fracture defect easily occurs.Second, on the one hand carrying out welding twice in same pad can cause
Solder is lost in, and causes the resistance of pad to increase, on the other hand lead-out wire can be caused to damage, cause the structural strength of pad
Reduce, thus cause lead-out wire that melting fault easily occurs.Third, when once weld, it is necessary to pass through manual bending
Mode constantly adjusts direction and the angle of lead-out wire, causes lead-out wire easily to lose wear-out failure.Fourth, because three-phase is determined
The interpolar line of sub- winding lacks supporting construction, causes the bulk strength of interpolar line inconsistent, thus causes stator integrally to connect
Melting fault easily occurs under high vibration operating mode for line.Fifth, it is elastic larger due to polyester felt pan, cause cable to vibrate
When can impact stator entirety line, thus cause stator entirety line that melting fault easily occurs.Based on this, it is necessary to invent one
Kind brand-new asynchronous traction motor stator structure, vibrating fatigue easily occurs to solve existing asynchronous traction motor stator structure and breaks
Split failure, melting fault, lose the problem of wear-out failure.
The content of the invention
In order to solve existing asynchronous traction motor stator structure vibrating fatigue fracture defect, fusing event easily occur for the present invention
Hinder, lose the problem of wear-out failure, there is provided a kind of asynchronous traction motor stator structure for strengthening vibration resistance.
The present invention adopts the following technical scheme that realization：
Strengthen the asynchronous traction motor stator structure of vibration resistance, including stator core, the three-phase that is set around in stator core
Stator winding, three cables for being arranged at End zone of stator core and pressure-sensitive felt pan, pad are located at three between cable and stator core
Three polyester felt pans；Also include the three formed lead heads and support ring for being arranged at End zone of stator core；Wherein, threephase stator
Coated insulation layer after three head end lead-out wires of winding weld with the head end of three formed lead heads respectively；Threephase stator winding
Coated insulation layer after three end lead-out wires weld with the end of three formed lead heads respectively；The end of three cables respectively with
Coated insulation layer after the middle part welding of three formed lead heads；Each interpolar line of threephase stator winding with support ring colligation
Dipping lacquer hardens afterwards；Infiltration has the insulated paint by drying hardening in three polyester felt pans.
During work, the head end of three cables is connected with outside three phase mains.Outside three phase mains passes through three cables and three
Root formed lead head is powered to threephase stator winding, so that stator structure is started working.In the process, support ring is to three
Each interpolar line of phase stator winding forms support.Based on said process, compared with existing asynchronous traction motor stator structure,
The asynchronous traction motor stator structure of enhancing vibration resistance of the present invention possesses following advantage by using brand new：
First, the present invention is by using formed lead head so that the pad of lead-out wire is away from the pad of cable, so that respectively
Individual pad is no longer hanging, so as to effectively prevent caused by locomotive vibrates for a long time the fracture of pad vibrating fatigue therefore
Barrier.Second, the present invention is by using formed lead head so that same pad only needs once to be welded, and thus effectively avoids
The lead-out wire melting fault caused by welding twice.Third, the present invention eliminates by using formed lead head and passes through hand
The mode of work bending adjusts direction and angle this link of lead-out wire, thus effectively prevent lead-out wire and loses wear-out failure.
Fourth, the present invention is by using support ring so that the bulk strength of the interpolar line of threephase stator winding becomes consistent, thus has
Effect avoids the stator entirety line melting fault under high vibration operating mode.Fifth, the present invention has by drying by using infiltration
The polyester felt pan of the insulated paint of hardening, the elasticity of polyester felt pan is reduced, thus reduced whole to stator when cable vibrates
The impact of body line, so as to effectively prevent stator entirety line melting fault.
The present invention efficiently solves existing asynchronous traction motor stator structure and vibrating fatigue fracture defect, fusing easily occurs
Failure, the problem of wear-out failure is lost, suitable for High-power AC drives locomotive.
