Description

Low-speed direct driving servo permanent magnet motor stator and rotor
Technical field
The invention 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 with deceleration device high-speed electric expreess locomotive ratio eliminate decelerator, the frictional dissipation having lacked decelerator is in hgher efficiency, its control accuracy require higher than the motor of band decelerator.Existing motor have employed the design concept of multipole multiple-grooved when design, increasing of progression can 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 a relatively low scope, improves control accuracy for multistage being more beneficial for of low-speed direct driving motor.But still there is the defect that stable difference, control accuracy are not high and torsional forces is not high in existing low speed servo electric machine rotor.
Summary of the invention
For above-mentioned background technology Problems existing, the purpose of the present invention 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, the present invention 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 the motor winding and the stator core that adopt centralized winding technique molding, motor winding is by insulating paper parcel and stator core isolation, 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 the present invention can reach following beneficial effect: the rotor pole slot fit of motor of the present invention adopts 20/18, so be equivalent to two 10/9 pole slot fit unit machines, the concept so introducing two unit machines not only has very big advantage in 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 the structural representation of the present invention.
Fig. 2 is rotor punching structure schematic diagram of the present invention.
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 accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in FIG. 1 to 3, the rotor pole slot fit of motor adopts 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 adopts centralized winding method, and rotor core 7 is overrided to form by rotor punching 10, adopts 8 equally distributed pin 8 riveted joints fixing under certain pressure conditions, rotor punching does not adopt 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 serving well fixing to the magnetic pole of high speed rotating.
It is further preferred that design has 18 degree uniform 20 projection 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 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 very big effect.
