Description
Technical field
The utility model relates to a kind of motor stator coil supporting structures.
Background technique
For the stator coil of motor after embedding technology is embedded in stator core, end needs solid and reliable fixation, Cai Neng
Inside motor in complicated electromagnetism and vibration environment, guarantee the operation reliably and with long-term of motor.Motor stator coil is in motor operation
Middle to need to bear voltage and current that is huge and changing over time, this needs stator coil to have good phase insulation and over the ground
Insulation.So after stator coil is wrapped up through special insulating process stator core can be embedded in by embedding technology.Stator line
After circle insertion iron core, it is divided into lead end and non-lead end, both ends have different structures, so needing different fixed forms.
The non-lead end structure of stator coil is relatively easy, it is only necessary in the fixed stainless steel after wrapping insulation of coil lashing
End hoop, in coil bevel edge banding insulation soft end band, and by end hoop binding and fixing on the screw rod being connected with ironcore choke.Stator line
The lead end of circle sometimes also needs the alternate copper ring of major diameter due to needing to carry out lead-out wire and wiring, so lead end
Stator coil is fixed, lead copper ring is fixed, guarantee coil with the insulation distance of lead copper ring, lead copper ring insulation against ground away from
From requiring special consideration.
Traditional stator coil lead end fixed form are as follows: several screw rods are closed in stator coil welding or handle, to
It is bound round to end and fixation point is provided；Welding or handle close several metal brackets on stator coil, axially aligned to support
Lead copper ring.Although the form structure of this fixed stator coils and lead copper ring is simple and relatively reliable, long in motor
In phase operation, due to the vibration generated when magnetic fields and motor operation complicated in motor, it is be easy to cause screw bolt loosening, and
And since screw rod, bracket etc. are all metal material, so requiring by special insulated binding technique.Sometimes due to motor
The limitation of inner space, the space in the axial direction of stator lead end is extremely limited, causes the distance of bracket and stator coil close, needs
Additionally to increase pad insulating materials between stator coil end and bracket, but due to there is no attachment point, or due to insulation
The inaccuracy that the degrees of expansion of material is grasped causes fill insulant to loosen and even falls off, and influences insulation effect and motor
Safe operation.Sometimes due to the limitation of motor outer diameter, the width spaces on stator core coil are also extremely limited, it is difficult to guarantee
Insulation distance between screw rod and carriage screw, encounters this feelings, and condition would generally select to remove fixing end hoop after embedding
Screw rod, but can thus make state of the end hoop in not no fixed point, motor longtime running, end hoop has the possibility of loosening.
The design problem encountered in terms of fixed coil in these above-mentioned motor stators is required by detailed calculating and is examined
Amount.Need to calculate the rule that the bevel edge angle of coil, coil highest point outer diameter, coil stretch out the length of stator core, lead copper ring
Lattice and diameter, motor inner radial and axial space etc., under the premise of meeting electromagnetic scheme, how the layout of safe and reasonable just
It is particularly important.
Summary of the invention:
The purpose of the utility model is to provide a kind of motor stator coil supporting structures, pass through the excellent of the coil brace structure
Change layout, both can guarantee that stator coil and end hoop and lead copper ring were reliably fixed, and also can guarantee stator coil and lead copper ring
Insulation distance, stator coil insulation against ground distance, the insulation distance of lead copper ring over the ground.The technical solution of the utility model are as follows:
A kind of motor stator coil supporting structure, motor stator coil bracket 1 is with stator coil 5 by carrier base 2 by the way that conjunction bolt 3 is connected
It connects and is fixed together, stator coil 5 is fitted in 4 outside both ends of the surface of electric machine stator iron, and 1 lower part of motor stator coil bracket is fixed
The insulation soft end band 8 of stator coil 6, the stainless steel end hoop 7 of stator coil end highest point, stator coil end bevel edge, motor
1 top anchor leg copper ring 9 of stator coil support.
The stator coil support 1, according to the bevel edge angle of motor stator coil 5 and 9 size of lead copper ring and motor
Internal space requirements are processed to trapezoidal to meet the needs of 6 end of fixed stator coils and lead copper ring 9,12 stator lines
It is two groups that coil support 1, which is divided to, every 6 one group, by the carrier base 2 of 1 two sides of stator coil support, by the way that conjunction bolt 3 fixes conjunction
On the stator coil 5 of 4 two sides of stator core, the lower part of stator coil support 1 is opened there are two waist hole, is respectively used to fixed stator
The non-lead end of coil 6 and the stainless steel end of lead end hoop 7 and insulation soft end band 8, the top of the coil brace 1 of lead end is according to 4
A 9 size of lead copper ring and relative position, process 4 waist holes, are used for anchor leg copper ring 9.
The utility model mainly designs and manufactures a kind of motor stator coil supporting structure.By calculating stator core line
Circle and motor inner space, to determine the suitable dimension of stator coil support, layout structure is as shown in Figure 1.Stator coil branch
Frame by two sides carrier base, by being secured firmly to stator core coil two sides, as shown in Figure 2 conjunction bolt and lock washer.
The advantages of the utility model: screw rod and support of the stator coil support instead of the fixing end hoop in general structure
The bracket of lead copper ring, while playing the role of fixed stator coils and end hoop and support lead copper ring, so that the knot of motor
Structure is more simple, and wiring layout is also more reasonable.
It is influenced since motor stator coil will receive complicated magnetic field in motor operation, easily deforms and vibrate, institute
It is necessary for being fixed in large-size machine with good end.In carrier base of the coil brace two sides to fixed coil bracket,
It is by the preferable angle steel Q235 processing and fabricating of rigidity.It is non-conjunction bolt and lock washer are all made of used in locking bracket seat
Zinc-plated material, because the insulated paint that the material of zinc-plated material can impregnate motor pollutes.It is fixed in traditional fixed form
Hold the screw rod of hoop generally using being fixed on stator coil in the form of closing or welding, although it is simple to do so structure,
When later period encounters maintenance or replacement, the mode for destroying screw rod can only be just taken.Coil branch described in the utility model
Frame is fixed conjunction bolt for 8 totally by left and right, conjunction bolt underlay lock washer, is guaranteeing that coil brace is reliably fixed in stator line
While on circle, it is also convenient for maintenance and repair in the future.
Material used in coil brace is epoxy resin bonded fiber 3240, is providing the same of secure support for stator coil
When, it can also play good insulation against ground effect.By carrying out mechanical analysis and intensive analysis to stator coil support, tradeoff is fixed
The safe distance of sub- each section insulation, selects the coil brace of suitable dimension and Rational Thickness, to guarantee that stator coil end exists
Safety when motor longtime running is firm.
