Abstract
The utility model discloses a kind of rotor of permanent magnetic synchronous traction machine, comprise rotor body (1) and be arranged on the plural block magnet steel (2) in rotor body (1) circumference, N pole magnet steel and S pole magnet steel are intervally arranged, N pole magnet steel and S pole magnet steel are along the incorgruous inclination of described rotor body (1) axis, and described N pole magnet steel is equal with the inclination angle between described S pole magnet steel with described rotor body (1) axis.The rotor of the permanent magnetic synchronous traction machine that the utility model provides, effectively can suppress the harmonic wave of traction machine, and can not reduce the inverse electromotive force of traction machine, can improve the operating efficiency of traction machine.
Description
Technical field
The utility model relates to elevator technology field, particularly a kind of rotor of permanent magnetic synchronous traction machine.
Background technology
Sizable share is occupied in the market at the elevator traction machine permanent magnetic synchronous traction machine run, traction machine is the core driver part in elevator device, the excitation source of permanent-magnetic tractor is permanent magnetic steel, what traction machine generally adopted is that mark winding is to suppress high order harmonic component, rotor magnetic steel adopts oblique pole or stator slot to adopt skewed slot to suppress the amplitude of low-order harmonic, but the method for the suppression low-order harmonic adopted at present is at the inverse electromotive force to a certain degree weakening traction machine, makes the efficiency of traction machine reduce.
Utility model content
The utility model object is to provide a kind of rotor of permanent magnetic synchronous traction machine, effectively can suppress the harmonic wave of traction machine, can not reduce again the inverse electromotive force of traction machine, can improve the operating efficiency of traction machine.
Based on the problems referred to above, the technical scheme that the utility model provides is:
A kind of rotor of permanent magnetic synchronous traction machine, comprise rotor body and be arranged on the plural block magnet steel in rotor body circumference, N pole magnet steel and S pole magnet steel are intervally arranged, N pole magnet steel and S pole magnet steel are along the incorgruous inclination of described rotor body axis, and described N pole magnet steel is equal with the inclination angle between described S pole magnet steel with described rotor body axis.
Further, described magnet steel is axially evenly divided into some sections along described rotor body, and each section of magnet steel of homopolarity is along described rotor body axial distribution and arrange stepped successively, homopolarity magnet steel and described rotor body axially between form inclination angle.
The utility model has the advantages that:
1, adopt the technical solution of the utility model, traction machine electronics rotor magnetic steel adopts incorgruous oblique pole, effectively can suppress the harmonic wave of traction machine, and can not reduce the inverse electromotive force of traction machine, can improve the operating efficiency of traction machine.
2, adopt the further technical scheme of the utility model, by incorgruous oblique pole subsection setup, production technology is more simple, can reduce production cost.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the partial schematic diagram of the rotor embodiment of the utility model permanent magnetic synchronous traction machine;
Fig. 2 is the plane outspread drawing of magnet steel in the utility model embodiment;
Wherein: 1, rotor body; 2, magnet steel.
Embodiment
Below in conjunction with specific embodiment, such scheme is described further.Should be understood that these embodiments are not limited to for illustration of the utility model limit scope of the present utility model.The implementation condition adopted in embodiment can do further adjustment according to the condition of concrete producer, and not marked implementation condition is generally the condition in normal experiment.
See Fig. 1, for the structural representation of the utility model embodiment, a kind of rotor of permanent magnetic synchronous traction machine is provided, it plural block magnet steel 2 comprising rotor body 1 and be arranged in rotor body 1 circumference, N pole magnet steel and S pole magnet steel are intervally arranged, between homopolarity magnet steel 2 and described rotor body 1 axis, there is inclination angle, N pole magnet steel and S pole magnet steel are along rotor body 1 axially incorgruous inclination, and N pole magnet steel is equal along the inclination angle between rotor body 1 axis with S pole magnet steel, the incorgruous tilt distribution of magnet steel 2 sees not oblique pole on the whole, effectively can suppress the harmonic wave of traction machine, and the inverse electromotive force of traction machine can not be reduced, thus the operating efficiency of traction machine can be improved.
In order to optimize the beneficial effects of the utility model further, solve incorgruous oblique pole to magnetize technology and technologic problem at magnet steel, make production technology simpler, see Fig. 2, above-mentioned magnet steel 2 is axially evenly divided into some sections along rotor body 1, every section of magnet steel of homopolarity is also arranged stepped along rotor body 1 axial distribution respectively successively, such homopolarity magnet steel and rotor body 1 axially between form inclination angle, N pole magnet steel and S pole magnet steel along rotor body 1 axially incorgruous inclination and they and rotor body 1 axially between inclination angle equal.
Above-mentioned example, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art person can be understood content of the present utility model and implement according to this, can not limit protection range of the present utility model with this.All equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection range of the present utility model.
