Abstract
The invention discloses a synchronous motor which comprises a rotor, the rotor is arranged to be circular ring shaped, winding tooth spaces are arranged on the periphery of the circular ring, and a projection is arranged between each two adjacent tooth spaces. Each projection which is additionally arranged between each two adjacent tooth spaces of the rotor is part of an iron core, so that magnetic fields formed by adjacent windings are effectively applied to the iron core via the projections, magnetic field intensity is enhanced, and further efficiency is improved.
Description
Technical field
The present invention is a kind of synchronous machine.
Background technology
Synchronous machine is the rotor speed alternating current motor identical with the rotating speed of stator rotating magnetic field at present, that winding type stator and winding type rotor consist of mostly, the structure of common synchronous machine, adjacent winding is to share a teeth groove in its rotor, saved material, but reduced magnetic energy utilization, so efficient is low.
Summary of the invention
The purpose of this invention is to provide a kind of synchronous machine, solve inefficient problem in the existing product.
Purpose of the present invention is come specific implementation by the following technical programs: a kind of synchronous machine, comprise rotor, and this rotor is made as circular, and the periphery of this annulus is provided with the coiling teeth groove, is provided with projection between adjacent teeth groove.
Further, the anglec of rotation of this teeth groove is protruding anglec of rotation 2-5 times.
Further, the anglec of rotation of this teeth groove is 2 times of the anglecs of rotation of projection.
Set up projection between the synchronous machine of the present invention coiling teeth groove that rotor is adjacent, because this projection is the part of iron core, therefore the magnetic field that forms of adjacent coiling is applied in iron core effectively through this projection, has strengthened magnetic field intensity, thereby has improved efficient.
Description of drawings
The below is described in further detail the present invention with embodiment with reference to the accompanying drawings.
Fig. 1 is the structure chart of the described synchronous machine of the embodiment of the invention;
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
As shown in Figure 1, the described synchronous machine of the embodiment of the invention comprises rotor 1, and this rotor is made as circular, and the periphery of this annulus is provided with coiling teeth groove 11, is provided with projection 12 between adjacent teeth groove 11.
Because rotor 1 is circular, projection 12 is parts of iron core, belongs to permeability magnetic material, therefore the magnetic field that produces of teeth groove 11 coilings in protruding 12 both sides, will produce magnetic fields to projection 12, namely this part magnetic energy has also obtained utilization, can not slattern as existing product.Therefore comparatively speaking, product of the present invention will improve efficient.
Selectively, the anglec of rotation 2-5 that the anglec of rotation (as shown in Figure 2, referring to the corresponding angle of teeth groove, shown in dotted line) of teeth groove 11 is made as projection doubly most preferably is made as 2 times.
Claims (3)
1. a synchronous machine comprises rotor, it is characterized in that: this rotor is made as circular, and the periphery of this annulus is provided with the coiling teeth groove, is provided with projection between adjacent teeth groove.
2. synchronous machine as claimed in claim 1 is characterized in that: the anglec of rotation of this teeth groove for the anglec of rotation 2-5 of projection doubly.
3. synchronous machine as claimed in claim 2 is characterized in that: the anglec of rotation of this teeth groove is 2 times of the anglecs of rotation of projection.
