Description

The super energy saving rare earth permanent-magnet synchronization motor of ultra high efficiency
Technical field
The present invention relates to magneto fields, more particularly to super ultra high efficiency energy saving rare earth permanent-magnet synchronization motor.
Background technology
Existing p-m rotor, since the structure designs such as magnetic circuit, silicon steel sheet are unreasonable, precision is poor, and rotor is caused to have The shortcomings of staring torque is small, poor radiation.And magnet steel bullet is easy to cause due to the relatively high magnetism of magnet steel in magnet steel installation process Go out, and magnet steel is easy to crack, cannot be positioned using screw, causes the installation difficulty of magnet steel big, installation effectiveness is low.In the prior art, Magnet steel is held by the way that vallecular cavity is arranged in rotor core ontology, magnet steel is fixed by fixative again, and this mode is operationally Although simple, exist after motor is operated and generated heat, curing agent will appear thawing phenomenon, lead to magnet steel position offset, gently then Electrical machinery life is set to decline, it is heavy then motor is made to scrap, influence production requirement.
For high rotating speed rotor, even there is the eccentricity of very little, can also cause very big centrifugal force, cause motor Vibration generates noise, accelerates the abrasion of bearing, causes rotor part high-cycle fatigue to destroy, reduces the service life of motor.Cause This, the dynamic balancing of rotor is in the manufacturing process of motor in occupation of very important status.For unbalanced correction form, one As using twisting mass screw, balancing block, welding weld tabs, drilling, grinding, the methods of turning.It is logical for high-speed rotating rotor It crosses and twists the precision that mass screw is extremely difficult to needs, the method for welding can have an adverse effect to rotor, the method for material removal With irreversibility, also have a certain impact to the intensity of rotor.Secondly, most to the dynamic balancing measurement of rotor and correction at present It is carried out under normal temperature state, and rotor then usual long-play at relatively high temperatures, and the variation of temperature often makes rotor New imbalance, especially rotating speed are generated in the high-speed electric expreess locomotive of 3000rpm or more, even small amount of unbalance will also cause The machine of motor shakes, and running quality to motor and service life bring more serious adverse effect.
Traditional rotor balancing structure opens up aperture by the side of counterweight and carries out loss of weight balance, and this balance mode has Control is inconvenient, and control range is small, adjusts the shortcomings of inaccurate.And traditional weightening structure has connection unreliable, it cannot be right The shortcomings that weight of specific location is adjusted.
Meanwhile traditional connection box for motor uses setting gasket between box cover and box body to be sealed, and is using bolt Box cover and box body are attached, the edge for the gasket installed in this way is exposed to be located outside, is easy by surrounding The corrosion of environment, to reduce its service life so that flue dust and moisture enter the problems such as terminal box causes electric motor short circuit;Simultaneously The shortcomings of there is poor corrosion resistances for metal box-lid, process inconvenience, and cost is higher.
