Description
Technical field
This utility model belongs to rotor technical field, especially relevant with a kind of low-speed direct driving servo permanent magnet motor stator and rotor.
Background technology
Low-speed direct driving motor in servomotor field and band deceleration device high-speed electric expreess locomotive ratio eliminate decelerator, the frictional dissipation having lacked decelerator is in hgher efficiency, and its control accuracy requires higher than the motor of band decelerator.Existing motor have employed the design concept of multipole multiple-grooved when design, progression increase so that motor provides big torque, although the frequency of progression is many motor is as well as increase, but owing to the rotating speed of motor self is low, the iron loss of motor still in relatively low scope, improves control accuracy for multistage being more beneficial for of low-speed direct driving motor at a ratio.But the defect that existing low speed servo electric machine rotor still exists stable difference, control accuracy is the highest and torsional forces is the highest.
Summary of the invention
The problem existed for above-mentioned background technology, the purpose of this utility model aims to provide that a kind of servomotor stationarity when low speed is good, control accuracy is high and can provide the low-speed direct driving servo permanent magnet motor stator and rotor of big moment of torsion.
For this, this utility model is by the following technical solutions: low-speed direct driving servo permanent magnet motor stator and rotor, including stator and rotor, it is characterized in that, described stator includes motor winding and the stator core using centralized winding technique molding, motor winding is isolated with stator core by insulating paper parcel, described rotor includes being overrided to form rotor core by rotor punching, magnetic pole, rotating shaft and without latitude band, described rotor core and rotating shaft are fixedly connected by keyway, magnetic pole is uniformly distributed on described rotor core outer peripheral face, described band without latitude is wrapped in the surface of magnetic pole and rotor core and is fixed on rotor core by magnetic pole.
Use this utility model can reach following beneficial effect: the rotor pole slot fit of this utility model motor uses 20/18, so be equivalent to two 10/9 pole slot fit unit machines, the concept so introducing two unit machines not only has the biggest advantage in terms of reducing cogging torque, it can in addition contain reduce the unilateral magnetic force of former 10/9 unit machine motor, therefore control accuracy is improved for multistage being more beneficial for of low-speed direct driving motor, motor is run more steady, be conducive to improving the vibration of motor, noise problem.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is this utility model rotor punching structure schematic diagram.
Fig. 3 is the center of circle distance schematic diagram of two sections of circular arcs of the bottom surface of magnetic pole and end face.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described in detail.
As shown in FIG. 1 to 3, the rotor pole slot fit of motor uses 20/18, motor stator is made up of stator core 1, insulating paper 2, motor winding 3, rotor includes forming without latitude band 5, magnetic pole 6, rotor core 7, rotating shaft 9, motor winding 3 uses centralized winding method, rotor core 7 to be overrided to form by rotor punching 10, uses 8 equally distributed pin 8 rivetings fixing under certain pressure conditions, rotor punching does not use the mode of welding, reduces the eddy-current loss on rotor.Rotor core 7, rotating shaft 9 are affixed to together by key 4, use High-strength glue by 20 pieces of magnetic poles 6 by N the uniform surface being pasted onto rotor core 7 of S, band without latitude 5 is wrapped in the surface of the rotor core 7 gluing magnetic pole 6, play the effect of fixed magnetic pole 6, thus the magnetic pole of high speed rotating is served the most fixing.
It is further preferred that be designed with 18 degree of uniform 20 projections 10 on rotor punching 10, play the effect separating magnetic pole 6,20 pieces of magnetic poles are evenly distributed on the surface of rotor punching.
Further, such as Fig. 3, the bottom surface of magnetic pole 6 magnetic pole and end face are respectively two sections of circular arcs, form the center of circle of these two sections of circular arcs not on same point, preferably, it is designed to two circular arcs that eccentric throw is 40mm, so the cogging torque reducing magneto is had the biggest effect.
