Abstract
The utility model relates to a kind of Rotor Assembly structure.Described structure is evenly distributed with sunk structure on Rotor Assembly yoke portion cylindrical, and its depression lays respectively on rotor punching flank center line and rotor magnetic steel center line.Rotor magnetic steel is " one " font two-part structure, is embedded into respectively in rotor magnetic steel groove.Rotor Assembly is evenly divided into multistage in the axial direction, and the certain angle that staggers between every section of rotor sub-unit magnetic direction forms skewed-rotor structure.This Rotor Assembly structure can reach the object that reduces location torque.
Description
Technical field
The utility model relates to a kind of Rotor Assembly structure, is applicable to design of electrical motor and manufacturing field.
Background technology
At present, with motor-driven new-energy automobile, obtained extensive approval, motor is one of kernel component of car load, also be the major part that integral vehicle cost increases, therefore,, from car load application point, not only require motor to have output stably also will reduce production costs simultaneously.When cogging torque is crossed senior general and caused low vehicle speeds between electric machine rotor, there is " alarmming car " phenomenon, therefore, reducing motor location torque is very important target of design of electrical motor, in addition, the permanent magnet material consumption that reduces motor can reduce costs, improving product competitiveness.
Summary of the invention
The above-mentioned defect existing for overcoming prior art, the utility model proposes a kind of non-homogeneous air gap and sectional type motor rotor assembly structure, on rotor yoke cylindrical, be uniformly distributed sunk structure, certain angle staggers between every section of rotor sub-unit magnetic direction, form skewed-rotor structure, by said structure, can reach the object that reduces location torque.
The utility model solves the technical scheme that its technical problem adopts: a kind of Rotor Assembly structure is all designed with sunk structure on each flank of motor rotor punching sheet and the center line of rotor magnetic steel.Rotor magnetic steel is " one " font two-part structure, is embedded into respectively in rotor magnetic steel groove.Rotor Assembly is evenly divided into the multistage of equal altitudes in the axial direction, certain electrical degree that staggers between every section of rotor sub-unit magnetic direction, and its value is less than 10 °, forms skewed-rotor structure.
The beneficial effects of the utility model are: by magnet steel segmentation, can promote the mechanical strength of magnet steel; Skewed-rotor structure, can reduce location torque.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is rotor sub-unit structural representation.
Fig. 2 is the oblique electrode structure schematic diagram of rotor segmentation.
1. yoke portions in figure, 2. flank, 3. sunk structure, 4. magnet steel groove, 5. rotor magnetic steel, 6.A rotor sub-unit, 7.B rotor sub-unit, 8. rotor field spider, 9. key, 10. keyway, 11. rotor cores.
Embodiment
The following stated is only preferred embodiment of the present utility model, not scope of the present utility model is limited.
See Fig. 1, on its yoke portion 1 cylindrical of rotor sub-unit, be evenly distributed with sunk structure 3, its sunk structure 3 is positioned on the center line of rotor punching flank 2 and rotor magnetic steel 5, and is symmetric.Rotor magnetic steel 5 is " one " font two-part structure, is embedded into respectively in magnet steel groove 4.Rotor core 11 is connected by key 9 with rotor field spider 8.
See Fig. 2, the magnetic direction of A rotor sub-unit 6 and the B rotor sub-unit 73 ° of electrical degrees that spatially stagger, realize skewed-rotor.
