Description
Technical field
The invention belongs to permagnetic synchronous motor technical field, relate to a kind of solution permagnetic synchronous motor long start-up time, move the not method of plateau problem, relate to a kind of solid rotor core structure.
Background technology
In the permagnetic synchronous motor that at present industrial circle adopts, the Cogging Torque that the magnetic field being produced by permanent magnet produces with the teeth groove effect of armature core can make motor in running, produce torque ripple, move not steady, the problem such as service behaviour is poor.In variable speed drives, when the mechanical resonance frequency of torque pulsation frequency and stator or rotor is consistent, vibration and noise that location torque produces also will be exaggerated.The existence of location torque affects the low-speed performance of motor in speed control system and the hi-Fix in position control system equally.Along with the increasingly extensive use of the better permanent magnet of performance, the problem of location torque will be more outstanding.
Summary of the invention
The object of the invention is in order to solve permagnetic synchronous motor longly start-up time, move jiggly problem, a kind of solid rotor core structure is provided.
The object of the invention is to be achieved through the following technical solutions.
A kind of solid rotor core structure of the present invention, comprises rotating shaft, solid rotor pole core, magnetic shield cylinder, helical form ventilation slot, starts mouse cage embedding groove and spiral helicine permanent magnet embedding groove (anglec of rotation that θ is groove).Magnetic shield jacket casing is in the outside of rotating shaft, and solid rotor pole core forms a circle round magnetic shield cylinder; On the surface of solid rotor pole core, there is helical form ventilation slot, start mouse cage embedding groove and spiral helicine permanent magnet embedding groove; Helical form ventilation slot and startup mouse cage embedding groove alternately exist, and spiral helicine permanent magnet embedding groove has been symmetrically distributed two;
A kind of along rotor surface opening of solid rotor iron core surface uniform, spiral magnet steel groove, meanwhile, the ventilation slot on solid rotor surface is corresponding this helical form that is also.
The first, because this spiral magnet steel groove is along rotor surface, spiral, so variation has occurred the arrangement position of permanent magnet, the magnetic line of force distributes and also changes thereupon.In motor start-up procedure, there is change in the direction of the location torque that the teeth groove interaction of permanent magnet and stator core produces, the tangential location torque component of the armature spindle contrary with direction of rotation reduces, and the resistance of start square of motor reduces, staring torque increases, Acceleration of starting.
The second, because the axial location moment components between solid rotor and stator teeth groove reduces, in high speed operation of motor process, the moment of resistance diminishes, and vibrations and noise be corresponding reducing also, moves more steady.
The 3rd, the helical form ventilation slot on solid rotor surface has strengthened the axial draught area of motor solid rotor, strengthen motor cavity from heat-sinking capability; This groove has also strengthened the kelvin effect layer length of solid rotor when starting simultaneously, and collection takes effect area and strengthens, and the resistance on solid rotor surface strengthens, and the detent torque of motor has also increased, and is conducive to the startup of motor.
Beneficial effect
The inventive method, contrast prior art, is not only conducive to the quick startup of motor, and even running has also improved the ventilation and heat ability of motor self simultaneously.
