The beneficial effects of the utility model are that: guaranteed the complete magnetic flux of magnet steel, and can not cause the damage of magnet steel, made things convenient for the dismouting, easily carried out the change of magnet steel, very big improvement the utilization ratio of motor performance and material, simple structure, low in cost, convenient operation, wedge angle and wedge screw structure have guaranteed the stability of installation back magnet steel, and be firmly safe, is difficult for droing.
Description
Technical field
This utility model belongs to magneto technical field, and in particular to a kind of surface-mounted rotor structure.
Background technology
With energy-efficient continuous renewal, permanent magnet direct driving motor also replaces original asynchronous machine gradually, subtracts into energy-conservation
The motor ranks of row.Difference of the rotor structure according to permanent magnet mounting means, is divided into surface-mount type, embedded.Current surface-mount type magnetic
The mounting means of steel is divided into two kinds substantially：The magnet steel of gluing and screw-driving punching.Wherein gluing mode install after magnet steel,
Cannot remove again, if rotor magnetic steel goes wrong, whole rotor can only be changed.Second mounting means, needs magnet steel
Punching, magnet steel is tightened to the outer surface of rotor rim with sunk screw, and this mode is easy for installation, and magnet steel is also easily changed, but
It is to punch on the magnetizing direction of magnet steel, on the one hand affects the magnetic flux on magnetizing direction, the performance of motor is impacted, separately
On the one hand, the magnet steel after compacting is more crisp, and tightening magnet steel needs the screw of certain diameter, be difficult it is too small, therefore in punch position
Intensity it is very weak, when screw is tightened with certain screwing force, magnet steel is twisted into broken easily, cause in production greatly not
Just and waste.
The content of the invention
The drawbacks of existing for both the above mounting means, this utility model optimization Electromagnetic Design on the basis of, to table
Mounted rotor structure is optimized design, sets about from reduction magnetic losses and easy disassembly, improves original mounting means.Specifically
Technical scheme is as follows：
A kind of surface-mounted rotor structure, including magnet steel, rotor rim, drift screw and drift；The rotor rim is in circle
Shape is distributed on the outside of rotating shaft；The magnet steel is distributed on the outside of rotor rim, and magnet steel edge has wedge degree, between two blocks of magnet steel
Groove is provided with, groove installs not magnetic conduction drift, and drift center is provided with through hole, through hole installs drift screw.
The drift screw top is truncated cone-shaped, and shape size mutually suited with the through hole at drift center, drift screw bottom
For cylinder, insert in rotor rim.
The wedge degree of the drift is mutually suited with the wedge degree at magnet steel edge.
Between two blocks of wedge shape magnet steel, the wedge angle of groove is more than magnet steel receding angle, prevents magnet steel from moving back abjection.Magnet steel
When receding angle is that magnet steel sideline is parallel with magnet steel center line, the wedge angle of groove between two blocks of magnet steel.
Between two blocks of magnet steel, the wedge angle of groove is 38 °.
In the embedded drift of the drift screw.
The beneficial effects of the utility model are：Ensure that the complete magnetic flux of magnet steel, and do not result in the damage of magnet steel, side
Just dismount, it is easy to carry out the replacing of magnet steel, greatly improve the utilization rate of motor performance and material, simple structure, low cost
Honest and clean, easy to operate, wedge angle and wedge screw structure ensure that the stability of magnet steel after installing, and securely, be difficult to take off
Fall.
Description of the drawings
Fig. 1 is surface-mounted rotor structure chart；
Fig. 2 is close-up schematic view；
In figure, 1, rotor rim, 2, magnet steel, 3, drift screw, 4, drift, 5, rotating shaft.
Specific embodiment
A kind of surface-mounted rotor structure, including magnet steel 2, rotor rim 1, drift screw 3 and drift 4；The rotor rim 1
It is rounded to be distributed on the outside of rotating shaft 5；The magnet steel 2 is distributed on the outside of rotor rim 1, and 2 edge of magnet steel has a wedge degree, two pieces
Groove is provided between magnet steel, groove installs not magnetic conduction drift 4, and 4 center of drift is provided with through hole, through hole installs drift screw 3.
3 top of drift screw is truncated cone-shaped, and shape size mutually suits with the through hole at 4 center of drift, and 3 bottom of drift screw is cylinder
Shape, inserts rotor rim 1.The wedge degree of the drift 4 is mutually suited with the wedge degree at 2 edge of magnet steel.Groove between two blocks of magnet steel
Wedge angle be 38 °, it is ensured that magnet steel installs stable and operation, quick detachable well.In the embedded drift of the drift screw, it is ensured that
Technical staff is not scratched when working.
The beneficial effects of the utility model are：Ensure that the complete magnetic flux of magnet steel, and do not result in the damage of magnet steel, side
Just dismount, it is easy to carry out the replacing of magnet steel, greatly improve the utilization rate of motor performance and material, simple structure, low cost
Honest and clean, easy to operate, wedge angle and bolt structure ensure that the stability of magnet steel after installing, securely, difficult for drop-off.When
It is when between two blocks of magnet steel, the wedge angle of groove is 38 °, the most stable and good operation that magnet steel is installed, quick detachable.Drift screw
Can ensure that in embedded drift that technical staff is not scratched when working.
