Abstract
The invention discloses a production method for uniform division of rotor magnetic poles. The method comprises the steps of preparing a rotor core body and magnetic poles, then producing contact portions on the rotor core body, sticking the magnetic poles to the rotor core body, and allowing the magnetic poles to contact the contact portions. Due to the limitation of the contact portions, the magnetic poles can be distributed on the rotor core body very uniformly, and meanwhile, the positions of the single magnetic poles on a rotor core can be effectively prevented from creeping and even failing. Since contact ribs are used as starting points, the production method is accurate in positioning and simple in manufacturing, and is suitable for flat magnetic pole arrays and spiral magnetic pole arrays. The method is used for producing motor rotors.
Description
Technical field
The present invention relates to the production method of a kind of rotor.
Background technology
Motor is a kind of equipment converting electrical current into into mechanical energy.It is to use the power on coil (namely stator winding) produce rotating excitation field and act on rotor formation electro-magnetic motor force rotation torque.Rotor includes rotor core and the magnetic pole set being distributed on rotor core, and the mode that magnetic pole set and rotor core often use splicing is attached.But finding during actually used, owing to motor is work when, magnetic pole set can bear the biggest tangential force, and the time one is long, and magnetic pole set position on rotor core can occur creep, finally occurs that magnetic pole set departs from the phenomenon of rotor core.
Summary of the invention
The technical problem to be solved in the present invention is: provide the production method of the uniform separation of a kind of rotor magnetic pole.
The present invention solves the solution of its technical problem:
The production method of the uniform separation of a kind of rotor magnetic pole, comprises the steps:
A) it is ready to along the rotor core body front and back extended and magnetic pole；
B) generate on rotor core body along the abutting part front and back extended by welding procedure on rotor core；
C) magnetic pole is bonded on rotor core body, and makes magnetic pole abut with described abutting part.
Further as technique scheme, first completes the making of all abutting parts, and all abutting parts are uniformly laid on rotor core body, are then carrying out the bonding of magnetic pole.
Further as technique scheme, the making of abutting part and magnetic pole bonding alternately.
Further as technique scheme, described rotor core body is tubular element.
Further as technique scheme, described abutting part includes a continuous print sealing wire.
Further as technique scheme, described abutting part includes two spaced continuous print sealing wires.
Further as technique scheme, described abutting part includes one by the sealing wire of multiple welded spot pitches arrangement.
Further as technique scheme, described abutting part includes that two are arranged by the sealing wires of multiple welded spot pitches arrangement, described two sealing wires interval.
Further as technique scheme, the height of described abutting part is between 1mm to 4mm
Further as technique scheme, the width of described sealing wire is between 1mm to 6mm.
The invention has the beneficial effects as follows: the production method of the uniform separation of a kind of rotor magnetic pole, first will get out rotor core body and magnetic pole, then on rotor core body, produce abutting part, the most again magnetic pole is bonded on rotor core body, and make magnetic pole abut with described abutting part, owing to there being the spacing of abutting part, therefore magnetic pole can be spread evenly across on rotor core body, can be effectively prevented magnetic pole monomer position on rotor core can occur creep simultaneously, even loses efficacy.Owing to having abutting muscle as starting point, therefore accurate positioning of the present invention, it is simple to manufacture, is not only suitable for the magnetic pole row with flat, is also well suited for spiral helicine magnetic pole row.The present invention is for the production of motor rotor.

Detailed description of the invention
Below with reference to embodiment and accompanying drawing, the technique effect of design, concrete structure and the generation of the present invention is clearly and completely described, to be completely understood by the purpose of the present invention, feature and effect.Obviously; described embodiment is a part of embodiment of the present invention rather than whole embodiment, based on embodiments of the invention; other embodiments that those skilled in the art is obtained on the premise of not paying creative work, belong to the scope of protection of the invention.It addition, all connection/annexations being previously mentioned in literary composition, the most singly refer to that component directly connects, and refer to couple auxiliary according to being embodied as situation by adding or reducing, form more excellent draw bail.Each technical characteristic in the present invention, can be with combination of interactions on the premise of the most conflicting conflict.
Seeing figures.1.and.2, this is embodiments of the invention a1, specifically:
The production method of the uniform separation of a kind of rotor magnetic pole, comprises the steps:
A) it is ready to along the rotor core body 1 front and back extended and magnetic pole 2；
B) generate on rotor core body 1 along the abutting part front and back extended by welding procedure on rotor core；
C) magnetic pole 2 is bonded on rotor core body 1, and makes magnetic pole 2 abut with described abutting part.
Owing to there being the spacing of abutting part, therefore magnetic pole can be spread evenly across on rotor core body, and can be effectively prevented magnetic pole monomer position on rotor core can occur creep simultaneously, even loses efficacy.Owing to having abutting muscle as starting point, therefore accurate positioning of the present invention, it is simple to manufacture, is not only suitable for the magnetic pole row with flat, is also well suited for spiral helicine magnetic pole row.According to different production requirements, can first generate all of abutting part and paste magnetic pole 2 again, it is also possible to often produce an abutting part and be just stained with the magnetic pole 2 of correspondence.
For the motor that some volumes are bigger, its rotor is the most relatively large, and the space that can process abutting part is more, includes two spaced continuous print sealing wires 3 for saving the material described abutting part of event.In order to save material, described abutting part can be two sealing wires 3 arranged by multiple welded spot pitches.
The present invention is to the structure of rotor core body 1 and has no special requirements, but disclosure is particularly well suited to the rotor core body 1 of tubulose, and the rotor core body 1 of tubulose can reduce the rotary inertia of rotor core.
With reference to Fig. 3 and Fig. 4, this is embodiments of the invention a2, specifically:
For the motor of some small volumes, its rotor is the most relatively small, can process the limited space of abutting part, therefore described abutting part includes a continuous print sealing wire 3.Certainly, in order to save material, described abutting part can be a sealing wire arranged by multiple welded spot pitches.
In order to reduce magnetic leakage and save material, the height of described abutting part is between 1mm to 4mm
In order to reduce magnetic leakage and save material, the width of described sealing wire 3 is between 1mm to 6mm.
