Abstract
The invention discloses a non-circular rotor sheet applied to a motor. The non-circular rotor sheet comprises a rotor sheet main body, wherein the outer circumferential edge of the rotor sheet main body is outwards provided with even number of bulges enabling the appearance of the rotor sheet main body to be in a non-circular shape, and the bulges are arranged on the outer peripheral edge part of the rotor sheet main body in pairs and are symmetrical by using the center of the rotor sheet mian body as the symmetry center, so that the appearance of the rotor sheet main body is in a non-circular shape. The appearance of the rotor sheet main body is in the non-circular shape, so that the gravity center of the rotor sheet main body can be regulated according to the arrangement of different bulges, further, the non-circular rotor sheet has the sufficient torque and overloading capability under the condition of high rotating speed, when the rotating speed is low, the normal starting can be realized, and in addition, the sufficient torque and the stable operation performance are realized, so that the special performance requirement of some motors can be met.
Description
Technical field
The present invention relates to machine field, particularly a kind of non-circle rotor sheet being applied to motor.
Background technology
As everyone knows, the profile of the rotor sheet of the motor of the existing overwhelming majority is all that as depicted in figs. 1 and 2, the rotor sheet in Fig. 1 is cast-aluminum rotor sheet, and the rotor sheet in Fig. 2 is p-m rotor sheet, and the profile of two kinds of rotor sheets is all in positive toroidal in positive toroidal.Although the above-mentioned rotor sheet in positive toroidal is convenient to produce, also can meets the service behaviour requirement of general motor simultaneously, for the motor that some is special, then can not meet the property requirement of those motors well.
Summary of the invention
In order to solve the problem, the object of the present invention is to provide a kind of structure simple, the non-circle rotor sheet that the property that simultaneously can meet some motor requires.
The present invention is the technical scheme that its technical problem of solution adopts:
A kind of non-circle rotor sheet being applied to motor, comprise a rotor sheet main body, the outer peripheral edges of described rotor sheet main body make the profile of this rotor sheet main body be the projection of non-round type toward being outside equipped with even number, described in raise into be arranged at rotor sheet main body outer peripheral edges place and about the Central Symmetry of rotor sheet main body.
As the improvement of technique scheme, described projection and rotor sheet main body are formed in one.
As the further improvement of technique scheme, the outer peripheral edges place of described rotor sheet main body is provided with four projections, and circular arc identical sized by four projections are equal is protruding, and four circular arc projections are uniformly distributed in the outer peripheral edges places of described rotor sheet main body.
In the present invention, two adjacent circular arc projections are interconnected and smoothly transit
The invention has the beneficial effects as follows: the present invention by the outer peripheral edges in rotor sheet main body toward being outside equipped with even number projection, above-mentioned raise into be arranged at described rotor sheet main body outer peripheral edges place and about the Central Symmetry of rotor sheet main body, thus make the profile of above-mentioned rotor sheet main body be non-round type, profile due to rotor sheet main body of the present invention is non-round type, therefore the center of gravity of this rotor sheet main body can adjust according to arranging different projections, and then make non-circle rotor sheet of the present invention have enough torques and overload capacity in high-revolving situation, when the slow-speed of revolution, can normal starting there is enough moments of torsion and stable runnability, thus meet the property requirement of some motor.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Fig. 1 is the part drawing of traditional cast-aluminum rotor sheet;
Fig. 2 is the part drawing of traditional p-m rotor sheet;
Fig. 3 is the part drawing of the non-circle rotor sheet in the present invention.
Embodiment
With reference to Fig. 3, a kind of non-circle rotor sheet being applied to motor, comprise a rotor sheet main body 10, the outer peripheral edges of described rotor sheet main body 10 make the profile of this rotor sheet main body 10 be the projection 11 of non-round type toward being outside equipped with even number, described protruding 11 be arranged in pairs rotor sheet main body 10 outer peripheral edges place and about the Central Symmetry of rotor sheet main body 10, here, as the preferred embodiments of the present invention, described protruding 11 are formed in one with rotor sheet main body 10, when producing non-circle rotor sheet of the present invention, the rotor sheet main body 10 of stamping forming mode directly by described can be adopted out die-cut with projection 11, fast simple and convenient, avoid processing outer rim.
The present invention by the outer peripheral edges in rotor sheet main body 10 toward being outside equipped with even number projection 11, above-mentioned projection 11 be arranged in pairs described rotor sheet main body 10 outer peripheral edges place and about the Central Symmetry of rotor sheet main body 10, thus make the profile of above-mentioned rotor sheet main body 10 be non-round type, profile due to rotor sheet main body 10 of the present invention is non-round type, therefore the center of gravity of this rotor sheet main body 10 can adjust accordingly according to arranging different projections 11, and then make non-circle rotor sheet of the present invention have enough torques and overload capacity in high-revolving situation, when the slow-speed of revolution, can normal starting there is enough moments of torsion and stable runnability, thus meet the property requirement of some motor.
Further, in order to make non-circle rotor of the present invention, operationally its service behaviour is more stable, preferably, the outer peripheral edges place of described rotor sheet main body 10 is provided with four projections 11, circular arc identical sized by four projections 11 are equal is protruding, four circular arc projections are uniformly distributed in the outer peripheral edges place of described rotor sheet main body 10, and further preferably, two adjacent circular arc projections are interconnected and smoothly transit.
The foregoing is only preferred embodiments of the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
