Description
Technical field
The utility model relates to series excited machines, and in particular to a kind of series excited motor stator coil windings insulation framework.
Background technique
Currently, market increasingly increases the demand of motor, therefore to product quality, production efficiency requires to be continuously improved,
Motor is made of two main components of stator and rotor, and motor stator generally uses insulation framework, and insulation framework is that one kind is set
In motor stator end, and the moulding that there is winding coil structure to design.It is old due to being improved to safety standard requirements
Insulation framework creepage distance has been unable to meet requirement, and old insulation framework creepage distance is 3.0mm, and old safety standard requirements >=
2.5mm, since new safety standard requirements are increased to >=4.0mm, old insulation framework structure has been unable to meet new safety mark
Alignment request.
Utility model content
The utility model provides a kind of series excited motor stator coil windings insulation framework and series excited motor stator, gram
Technical problem present in background technique is taken.

It is connected to hollow stent, and is corresponded to each other, and is matched with the formation of the pole shoe of stator core two sides；The retaining wall of two bobbin winder bracket point
It is not connected to corresponding curved wall and extends towards the outside of curved wall, and has between retaining wall and hollow stent and is used for series excitation
The space interval that the outside of the stator coil winding of motor arcuately side wall passes through；
The curved wall top side offers the L-shaped groove for being affixed on stator core pole shoe end face bottom surface, institute
It states L-shaped groove to extend towards border on the outside of the hollow stent, the height of L-shaped bottom portion of groove to the hollow stent top surface is
3mm, the width of the L-shaped groove are 2mm.
In preferred embodiment, the length of the L-shaped groove is 13mm, with a thickness of 1.3mm.
Compared with the prior art, it has the following advantages:

Specific embodiment
Please refer to Fig. 1, a kind of series excited motor stator coil windings insulation framework 1, including for being attached to series excited machine
The hollow stent of stator core end face and two bobbin winder brackets, two bobbin winder bracket respectively include curved wall 2 and retaining wall 3, two bobbin winder brackets
Curved wall 2 be connected to hollow stent, and correspond to each other, and matched with the formation of the pole shoe of stator core two sides.
The retaining wall 3 of two bobbin winder bracket is connected to corresponding curved wall 2 and extends towards the outside of curved wall 2,
And the space that there is the outside of the stator coil winding arcuately side wall for series excited machine to pass through between retaining wall 3 and hollow stent
Interval.
In specific structure, 2 top side of curved wall offers the L for being affixed on stator core pole shoe end face bottom surface
Font groove 4, the L-shaped groove 4 extend towards border on the outside of the hollow stent, 4 bottom of L-shaped groove to hollow branch
The height of top of support is 3mm, and the width of the L-shaped groove is 2mm.
In the present embodiment, the length of the L-shaped groove 4 is 13mm, with a thickness of 1.3mm.
Insulation framework described in the utility model is opened up on curved wall 1 for being affixed on stator core pole shoe end face bottom
The L-shaped groove 4 in face, the L-shaped groove height be 3mm, width 2mm so that creepage distance be 5mm, meet safety standard
It is required that creepage distance, be easy to process management and control, Workshop Production employee is easily operated, improve Product Safety.And the insulation framework
Convenient for production, high-efficient, product quality is also guaranteed.
Fig. 2 and Fig. 3 are please referred to, a kind of semi-finished product of series excited motor stator, including insulation framework 1, stator core 5 are shown
With insulating part 6, insulation framework 1 is matched with stator core 5, and the lower end surface 51 of the stator core is upper with insulation framework hollow stent
End face leans.
Two coil windings (not shown)s are additionally included, which is wound in stator core 5 respectively
With insulation framework 1, and at the both ends of stator core, two coil windings are respectively along the outside of the curved wall of insulation framework 2
It passes through.Due to having opened up L-shaped slot, so that the creepage distance of the structure is greater than the 4mm of safety requirement, meet safety standard.
