The permanent magnet machine rotor that inertia is little, performance is excellent.
Technical scheme：For achieving the above object, permanent magnet machine rotor of the present utility model includes rotating shaft, is sleeved in rotating shaft
Rotor field spider and be sleeved on rotor core on rotor field spider, by rotor core described in person two ends be respectively arranged with before
Balance end plate and back balance end plate, described forward horizontal stand end plate and back balance end plate are installed on rotor field spider.
Further, the two ends of described rotor field spider axial direction are equipped with depression lightening hole, its axial mid portion and institute
State rotating shaft cooperation.
Further, described rotor core is that multiple ring-type steel discs with through hole are laminated vertically and are formed, each steel
Through hole on piece is agreed with the external diameter of described rotor field spider, and is provided with the gap of multiple circumference uniform distributions in through hole；Rotor core has
There is the weld part that all steel discs are fixed together, described weld part is arranged on the weldering being connected into by the gap stacking of all steel discs
Connect in groove.
Further, the in the hole with rotor field spider suit of described rotor core is provided with least one axially extended projection
Rib, the excircle of described rotor field spider is provided with the recessed groove coordinating with described projection rib, and the quantity of described recessed groove is more than etc.
In the quantity of described projection rib, and each raised rib all has a recessed groove matched.
Further, the material of described rotor field spider is aluminum.
Further, described forward horizontal stand end plate and back balance end plate are processed by alloyed copper.
Beneficial effect：Permanent magnet machine rotor total quality of the present utility model is light, and rotary inertia is low, and structure is simple, dress
Just, rotor core adopts welding manner manufacture to formula, decreases the modes such as traditional bolt connection to the destruction of iron core and vortex
The impact such as heating, makes the service life of motor longer.
Brief description
Accompanying drawing 1 is the structure sectional view of permanent magnet machine rotor；
Accompanying drawing 2 is permanent magnet machine rotor perpendicular to axial sectional drawing.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further described.
As accompanying drawing 1 and the permanent magnet machine rotor shown in accompanying drawing 2, including rotating shaft 1, the rotor field spider 2 that is sleeved in rotating shaft 1,
And it is sleeved on rotor core 3 on rotor field spider 2, the two ends by rotor core described in person 3 are respectively arranged with forward horizontal stand end plate 4
With back balance end plate 5, described forward horizontal stand end plate 4 and back balance end plate 5 are installed on rotor field spider 2.Forward horizontal stand end plate 4 with after
The effect of balance end plate 5 is the total quality pre-and-post equalization making permanent magnet machine rotor, improves motor rotating property.Forward horizontal stand end plate
4 are processed by alloyed copper with back balance end plate 5, and duplicate removal is easy to process, and duplicate removal volume is less.One end of described rotating shaft 1
It is provided with screwed hole, the other end has the lightening hole of depth, lightening hole axially extends at the screwed hole along it so that rotating shaft 1
Axially major part region is hollow-core construction.
In order to mitigate the overall weight of permanent magnet machine rotor, the two ends of described rotor field spider 2 axial direction are equipped with depression loss of weight
Hole, only its axial mid portion and described rotating shaft 1 coordinate, and rotor field spider 2 adopts casting aluminium material manufacture, it is possible to achieve in batches
Processing, reduces processing cost, shortens process time, the reduction of density, also reduce rotary inertia, improves motor response
Speed.
Described rotor core 3 is formed for multiple ring-type steel discs with through hole are laminated vertically, logical on each steel disc
The external diameter of hole and described rotor field spider 2 agrees with, and is provided with the gap of multiple circumference uniform distributions in through hole；Rotor core 3 has institute
There is the weld part that steel disc is fixed together, described weld part is arranged on the welding groove being connected into by the gap stacking of all steel discs
In 6.By way of welding, the rotor core 3 that manufactures decreases the modes such as traditional bolt connection to the destruction of iron core and vortex
The impact such as heating.
For rotor core 3 and rotor field spider 2 are carried out with circumference spacing, being set with rotor field spider 2 of described rotor core 3
In the hole be provided with least one axially extended projection rib, the excircle of described rotor field spider 2 is provided with is joined with described projection rib
The recessed groove closing, the quantity of described recessed groove is more than or equal to the quantity of described projection rib, and each raised rib all has a depression
Groove is matched.Preferably, described projection rib has one, described recessed groove has four, and the recessed groove setting can make permanent magnetism more
The assembling of rotor is more convenient.
The above be only preferred implementation of the present utility model it should be pointed out that：Common skill for the art
For art personnel, on the premise of without departing from this utility model principle, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
