Description

Super ultra high efficiency energy conservation rare earth permanent-magnet synchronization motor

Technical field

The utility model relates to magneto fields, more particularly to super ultra high efficiency energy conservation rare earth permanent-magnet synchronization motor.

Background technique

Existing p-m rotor, due to unreasonable structural designs such as magnetic circuit, silicon steel sheets, precision is poor, and rotor is caused to have The disadvantages of staring torque is small, poor radiation.And the magnetism in magnet steel installation process due to magnet steel is stronger, is easy to cause magnet steel bullet 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 positional shift, gently then Decline electrical machinery life, it is heavy then scrap motor, influence production requirement.

For high revolving 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 removing material 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 revolving speed are generated in the high-speed motor 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 disadvantages of inaccurate.And traditional weight gain 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, so that its service life is reduced, so that flue dust and moisture enter the problems such as terminal box causes electric motor short circuit；Simultaneously Metal box-lid is there is poor corrosion resistance, the disadvantages of processing is inconvenient, higher cost.
