Description
Technical field
The present invention relates to elevator part field, especially a kind of elevator traction machine that adopts embedded winding type stator.
Background technology
Lift for high rise building is because elevator lifting speed is fast, and pulling ability requires the high traction system to elevator to have higher requirement.Traction system mainly comprises towing machine, traction sheave, traction steel-cable or steel band.Traditional traction system adopts traction steel-cable traction, traction sheave cylindrical outer surface has the circumferential grooves cooperatively interacting with traction steel-cable, during traction, traction steel-cable is wrapped in traction sheave circumferential grooves, by the friction between steel rope and traction sheave, drives car movement.Which is in order to guarantee enough pulling abilitys, and the size of traction sheave is larger, and therefore the power of required traction motor is also larger.
At present elevator traction machine great majority are internal rotor and outer rotor, and stator adopts 48 grooves or multiple-grooved number more.Groove number more when rule efficiency low, easily make mistakes.
Elevator traction machine adopts the rotor of surface-mount type magnet steel substantially at present, and magnet steel surface brush glue, twines outward without latitude cloth, complex process, and bonding reliability is difficult to guarantee.
Summary of the invention
The object of the invention is just in order to overcome the deficiency of above-mentioned technology, and a kind of elevator traction machine that adopts embedded winding type stator is provided, this elevator traction machine has compact conformation, operates steadily, and noise is low, and the life-span is long, the advantage such as maintains easily and safe and reliable.
The present invention solves the technical scheme that its technical matters adopts: the elevator traction machine of the embedded winding type stator of this employing, it mainly comprises drg, brake wheel, front bearing, frame, main shaft, rear bearing, permasyn morot, bonnet and coder, and described brake wheel matches with main shaft; The number of stator slots that described permasyn morot adopts is 3n, n=4,5,6 ... 11,12, the embedded winding mode that described stator adopts is double-layer overlapped winding; The rotor number of poles that described permasyn morot adopts is 2n, and n is more than or equal to 4 natural number; Described rotor magnetic steel adopts insert structure.
Described drg is butterfly drg.
Described drg is caliper brake.
Described stator winding pitch is y=1,2,3,4 or 5.
The effect that the present invention is useful is: product with compact structure, has greatly reduced materials'use and simultaneously also reduced elevator operating cost and improved lift running safety and stability.

The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
Embodiment 1: as shown in Fig. 1,3,4,5, the elevator traction machine of the embedded winding type stator of this employing, it mainly comprises drg 1, brake wheel 2, front bearing 3, frame 4, main shaft 5, rear bearing 6, permasyn morot 7, bonnet 10 and coder 11, and described brake wheel 2 matches with main shaft 7.The stator 8 groove numbers that described permasyn morot 7 adopts are 3n, n=4,5,6 ... 11,12, the embedded winding mode that described stator 8 adopts is double-layer overlapped winding; Rotor 9 numbers of poles that described permasyn morot 7 adopts are 2n, and n is more than or equal to 4 natural number; The magnet steel of described rotor 9 adopts insert structure.Described stator 8 winding pitches are y=1,2,3,4 or 5.
Described drg 1 is butterfly drg, is arranged on braking both sides, storehouse, and the mouth that brake control lever is opened by braking both sides, storehouse stretches to brake wheel.When elevator brake, only have so the stressed brake wheel that simultaneously acts on radially, can not cause axial impulsive force to main shaft, guaranteed that the safe and reliable while of bearing has also guaranteed the safe and reliable of afterbody coder.
Embodiment 2: as shown in Figure 2, described drg 1 is caliper brake, are arranged on braking both sides, storehouse, and the mouth that brake control lever is opened by braking both sides, storehouse stretches to brake wheel 2, and caliper brake 1 quantity is defined as a set of, two covers.
In addition to the implementation, the present invention can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of requirement of the present invention.
