Abstract
The present utility model discloses a reinforced permanent-magnet synchronous motor rotor used for on-line starting. The rotor comprises standard punching sheets, conducting bars, magnet strips and reinforced punching sheets. The reinforced punching sheets are arranged between the standard sheets, the magnet strips are embedded into the standard punching sheets and separated by the reinforced punching sheets, and the conducting bars run through the laminated standard punching sheets and reinforced punching sheets. Compared with a permanent-magnet motor rotor structure in the prior art, the reinforced permanent-magnet synchronous motor rotor used for on-line starting provided in the present utility model effectively increases the mechanical strength of the motor rotor and prolongs the service life of the motor rotor through adding the reinforced punching sheets under the premise of not sacrificing the motor efficiency.
Description
Technical field
The utility model belongs to the permanent magnet synchronous motor technical field, specifically is the motor rotor that is applied in the online startup permanent magnet synchronous motor.
Background technology
In the prior art, online startup permanent magnet synchronous motor mainly adopts embedded high-intensity permanent magnet to produce magnetic field and torque, and online startup permanent-magnet synchronous motor rotor mainly constitutes (as shown in Figure 1) by standard punching, magnet strip, sliver; The standard punching is provided with axis hole, sliver groove, embedded magnet groove and magnetic bridge (as shown in Figure 2).Online startup permanent-magnet synchronous motor rotor structure is as follows in the prior art: with standard punching stack and alignment, then magnet strip and sliver are inserted respectively in the embedded magnet groove and sliver groove of standard punching.For high-performance and the high usage that reaches magnet, need in the structure that embeds magnet, use very narrow structure to avoid too much magnetic leakage flux, these very narrow structures are exactly magnetic bridge, the standard punching that has magnetic bridge connects into motor rotor by sliver or cast aluminium, narrow magnetic bridge can bring runnability preferably, but can weaken the mechanical strength that is combined into behind the rotor simultaneously, cause reliability of products and life-span to be reduced, particularly be applied in the machine field that runs up, the centrifugal force of the magnet in the rotor will with square being directly proportional of rotating speed, the centrifugal force of magnet will produce bigger influence to the structural strength of magnetic bridge.
The utility model content
The utility model purpose: in order to solve the problems of the prior art, the utility model provides a kind of high-intensity online startup synchronous electric motor rotor.
Technical scheme: to achieve these goals, a kind of reinforced permanent-magnet synchronous motor rotor that is used for online startup described in the utility model comprises: standard punching, sliver, magnet strip; The described reinforced permanent-magnet synchronous motor rotor that is used for online startup also comprises: strengthen punching; Described reinforcement punching is between the standard punching; Magnet strip embeds in the standard punching and is reinforced punching to be separated, and sliver runs through superimposed standard punching and strengthens punching.
Described standard punching is provided with: axis hole, sliver groove, embedded magnet groove and magnetic bridge; Described axis hole is positioned at the center of standard punching, and described sliver groove is positioned at the edge, surrounding of standard punching, and described embedded magnet groove is between axis hole and sliver groove, and the connecting portion of described sliver groove and embedded magnet groove is a magnetic bridge.
Only be provided with in the described reinforcement punching and strengthen axis hole and strengthen the sliver groove; Described reinforcement axis hole is positioned at the center of strengthening punching, and described reinforcement sliver groove is positioned at the edge, surrounding of strengthening punching; The reinforcement axis hole of described reinforcement punching is consistent with the shaft hole diameter of standard punching; The reinforcement sliver groove of described reinforcement punching is consistent with the sliver groove shape of standard punching size.Having added in the utility model does not have the reinforcement of embedded magnet groove punching, has improved the intensity of the rotor of online startup synchronous motor, the efficient of not losing high-performance magnet again simultaneously.
Magnet strip described in the utility model is embedded in the embedded magnet groove of standard punching; Strengthen punching between the standard punching, and the reinforcement axis hole of strengthening punching aligns with the axis hole of standard punching, the reinforcement sliver groove of described reinforcement punching aligns with the sliver groove of standard punching; Sliver passes the sliver groove of alignment and strengthens the sliver groove, and then runs through the standard punching of all stacks and strengthen punching.
Beneficial effect: the reinforced permanent-magnet synchronous motor rotor that is used for online startup that the utility model provides compared with prior art has following advantage:
1, the reinforced permanent-magnet synchronous motor rotor that is used for online startup described in the utility model is compared with permanent magnet motor rotor structure of the prior art, strengthen punching by adding in the utility model, under the prerequisite of not sacrificing motor efficiency, effectively raise the mechanical strength of motor rotor, prolonged the useful life of motor rotor.
2, since motor rotor in the centrifugal force of permanent magnet when rotor turns round be proportional to rotating speed square, so when in the environment that rotor need be applied to run up, the mechanical strength of rotor will cause this rotor fails, the utility model is strengthened the mechanical strength that punching improves motor rotor by increasing, and can adopt the reinforcement punching of suitable quantity according to the requirement of different rotating speeds; The utility model does not need to change the shape of standard punching, does not influence the behavior in service of motor, has realized that motor is applicable to the requirement that different rotating speeds is used.
