As improving further and supplementing technique scheme, the utility model also comprises following additional technical feature.
The rotor tip end ring of the affixed firmly rotor core both ends of the surface of described joint pin.Easily the rotor punching of superposition can be tightened to rotor core.
Shaping and the affixed mode of described joint pin and rotor tip end ring, rotor tip end ring and balance columns is integrally casting.Integrally casting mode manufactures simply, quality stability is high and sound construction.
The described fastener be made up of joint pin, rotor tip end ring and balance columns is cast aluminium body.Aluminium casting mode cost is low, and technology maturation, casting temperature can not destroy rotor core.
Described balancing weight fastens on balance columns by the through hole set by its center.The side of balancing weight cements on the end face of rotor tip end ring.It is easy to operate that cementation mode increases balancing weight, and be stained with and take away all more convenient, and can firmly stick together, and can not come off.
Multiple described balancing weight can bond fastening mutually.Dynamic balance weight can be increased easily.
Described rotor punching be evenly provided with multiple dovetail groove along week, described permanent magnet build-in is in dovetail groove.Oat tail groove structure ensures that permanent magnet can not side direction come off.
The top arc face of described permanent magnet and the circular arc side of bottom arc surface and rotor core are concentric circle arc plane.Concentric structure ensures that rotor core itself possesses good dynamic balancing, and the counterweight of increase can be made relatively less.
Described balance columns and the quantity of permanent magnet are 8, and the symmetrical centre face of balance columns and permanent magnet and the axis of rotating shaft are in same plane.After rotor core increases permanent magnet, each permanent magnet has a corresponding balance columns for changing dynamic balance weight.
The cross section of described connecting hole, balance columns and balancing weight is circular.Circular manufacture is simple, and do not have acute angle, potential safety hazard is little in process of production.
Beneficial effect: relative to conventional permanent magnet motor rotor adopt rotor end plates loss of weight or add balance mud method to correct the amount of unbalance of p-m rotor, the utility model corrects the dynamic balancing of p-m rotor by balancing weight mode, and structure is more simple, process, easy to operate; By glue by firm for the permanent magnet dovetail groove being fixed on rotor core outer round surface, reduce magnet steel and to come off risk.

Embodiment
Below in conjunction with Figure of description, the technical solution of the utility model is described in further detail.
As shown in Figure 1, the p-m rotor of band balance columns, comprise be formed by stacking by rotor punching 1 rotor core 14, be admittedly embedded in evenly distributed 8 permanent magnets 8 of rotor side surface, be admittedly embedded in the rotating shaft 9 of rotor center axis.
In order to simplify the counterweight operating procedure of p-m rotor, realize dynamic balance weight more reliably, described rotor core 14 is fastening by fastener 5, described fastener 5 comprises the end ring 4 around being raised in rotor core 14 both ends of the surface, through the joint pin 6 of the circular connecting hole 2 of rotor punching 1, the end face of described end ring 4 is provided with and position one to one balance columns 13 equal with permanent magnet 8 quantity, the symmetrical centre face of balance columns 13 and permanent magnet 8 and the axis of rotating shaft 9 are in same plane, by described joint pin 6, the fastener 5 that end ring 4 and balance columns 13 form is integrated casting.Described balance columns 13 is provided with removably annular balancing weight 7, described balancing weight 7 fastens on balance columns 13 by the through hole set by its center, the side of balancing weight 7 cements on the end face of end ring 4, according to dynamically balanced actual counterweight requirements, more balancing weight 7 bonding can be fastened on the end face of previous balancing weight.
In order to reduce casting cost, the described fastener 5 be made up of joint pin 6, end ring 4 and balance columns 13 is cast aluminium body, and aluminium casting temperature is relatively low, can not because of high temperature grandson bad rotor core, and aluminium casting technology maturation.
For allowing permanent magnet more firmly cement on rotor core, there is not side direction and coming off, described rotor punching 1 along being evenly provided with multiple dovetail groove 3 week, described permanent magnet 8 build-in is in dovetail groove 3.
In order to realize best rotor dynamic balancing, the top arc face 11 of described permanent magnet 8 and bottom arc surface 10 are concentric circle arc plane with the circular arc side 12 of rotor core 14.
During production, first rotor punching 1 is laminated into rotor core 14, then by connecting hole (2) cast aluminium, produce a cast aluminium fastener 5, being connected and fixed by rotor core 14 is a firmly entirety, casts out equally distributed cylindrical balance columns 13, when correcting p-m rotor amount of unbalance on rotor tip end ring 4 simultaneously, corresponding balancing weight 7 through balance columns, and cement on end ring 4 end face; Glue is coated in dovetail groove (3)
In, inserted by end face of permanent magnet 8 by dovetail groove 3, good bond, at rotor core 14 outer round surface, reduces set magnet permanent body 8 and to come off risk.
The p-m rotor of the band balance columns shown in above Fig. 1-4 is specific embodiment of the utility model; the utility model substantive distinguishing features and progress are embodied; can according to the use needs of reality; under enlightenment of the present utility model; it is carried out to the equivalent modifications of the aspect such as shape, structure, all at the row of the protection range of this programme.
