Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in the utility model carry out it is clear,
It being fully described by, it is clear that described embodiment is only a part of the embodiment of utility model, instead of all the embodiments,
Based on the embodiments of the present invention, obtained by those of ordinary skill in the art without making creative efforts
Every other embodiment, fall within the protection scope of the utility model.
It is as shown in Figure 1 and Figure 2: low temperature resistant traction machine, using permanent magnetic synchronous traction machine, including base 1, armature spindle 3, rotor
Body 5, stator 6, brake, encoder and traction sheave 2；The stator 6 is mounted in base 1, fixed on the wall of the rotor block 5
Permanent magnet 11, rotor block 5 are fixedly installed on armature spindle 3, are fixed with traction sheave 2, brake and coding on the armature spindle 3
Drainage hole 9 is arranged in device, 1 bottom of base, and 1 bottom of base is arranged drainage hole 9, condensed water is exhausted in time.It prevents
The insulating surface condensation of traction machine even ponding, the insulation performance of traction machine will sharply decline even premature loss, and influence traction
The safe operation of machine.The brake is low temperature resistant brake 7, and the encoder is low temperature resistant encoder 8.
Base 1 can use welding frame or cast frame, and welding frame is welded using 16Mn material, welding frame weight
Light-weight compared with casting base, save the cost, geometrical body is adaptable, simple structure.Cast frame uses low-temperature high-toughness ball
Black cast iron materials QT400-18LT, -50 DEG C of operating temperature.The base 1 is used to support front and back bearings and stator core, installation system
It moves device and plays the role of supporting whole system weight；When 1 fixed stator 6 of base and bearing, need to guarantee bearing mounting hole and
Stator mounting hole concentricity and jitter values.
In the stator core manufacturing process, several stator core pieces of the stator are cold-rolled silicon iron, described
Several cold-rolled silicon irons laminate molding and form stator core, will first laminate molding stator core piece and be carried out with epoxy resin
It impregnates, it is affixed by epoxy resin between every two adjacent stator laminations, after firm insulating layer to be formed, in 120-
It is dried under 130 DEG C of high temperature, keeps the temperature 1.5-3 hours, place into low-temperature treatment in liquid nitrogen, (in such stator lamination all uniformly
Enclose one layer of insulating epoxy, that is, solve Insulation Problems and in turn ensure that low temperature is indeformable), then, can carry out rule stator around
Group 18, ensure that insulation of the winding to stator lamination with this, it is ensured that the insulation performance of the low temperature resistant traction machine of the utility model.
After the completion of stator 6 embeds the wire, with the poured with epoxy resin of low temperature, to guarantee the solidification of stator winding 18, heat dissipation and effectively prevent
Turn-to-turn short circuit.
Low temperature resistant epoxy resin-impregnated material due to insulation, it is heat-insulated, without magnetic disturbance, stability is good the advantages that become it is ultralow
Indispensable important materials are met low temperature resistant in temperature equipment with improving system anti-cracking performance and high-low temperature resistant impact property
The insulation processing requirement of traction machine.

Portion and end use the silicone rubber tube double-layer folding sleeve of different-diameter.Stator winding 18 is single or double layer form-wound coils, single
The half of overall coil number total iron core slot number of Zhan in iron core slot of layer winding.Because Single-layer Windings are only put in each iron core slot
A coil side is set, but there are two sides for a coil, therefore the overall coil number of Single-layer Windings is the half of iron core slot number.Single layer
Winding is exactly that a coil is only placed in each slot, two coil sides of placement in the certainly namely each slot of Double Layer Winding, and point
Upper and lower level, Single-layer Windings are used for small-power occasion.
The overall coil number of Double Layer Winding is equal with iron core slot number in iron core slot.Because Double Layer Winding is put in each slot
Two coil sides are set, centre is separated with layer insulation.Two sides of each coil, a upper layer in certain slot respectively, another
The lower layer of other slots.Therefore the overall coil number of Double Layer Winding is equal with the total slot number of iron core.
The advantages of the advantages of Double Layer Winding is exactly to cut down harmonic wave, Single-layer Windings is to facilitate embedding Double Layer Winding can be any
Short distance, Single-layer Windings can only be whole away from therefore bilayer is conducive to reduced harmonic.Double Layer Winding is mainly used for large-power occasions.
Enough mechanical strengths, good electric property and excellent thermal stability, stator winding 18 use end in order to obtain
Hoop is fixed.Special-shaped position (such as and head connecting portion, lead intermediate location) insulation weak link solution party of stator winding 18
