Description
Technical field
The utility model relates to electric motors, and in particular to a kind of better rotor arrangement of heat dissipation.
Background technique
Automobile current generator is the main power source of automobile, and function is to supply in normal working of engine to electrical equipment
Electricity, while charging to battery.
But a large amount of Joule heats can be generated when automobile current generator work, in order to cool down to generator, being commonly designed fan makes
Air-flow runs through entire generator, but conventional fan is typically all to be arranged in front, and heat dissipation effect is not obvious；Simultaneously
Orthodox car generator mostly uses single fan structure, and heat dissipation effect is poor.There are also because generator work when run at high speed,
Bad environments, rotor fixed position structure is easy deviation, serious to directly result in generator failure, not serious influence heat dissipation, when long
Between also result in generator cisco unity malfunction, reduce the structural reliability of generator, reduce its service life.
To sum up, above-mentioned traditional automobile current generator fan structure is unreasonable, frequently can lead to that heat dissipation effect is poor, and structure is reliable
The technological deficiency that property is poor, the service life is short.
Utility model content
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of better rotor arrangement of heat dissipation,
This rotor arrangement fan blade fixation is more stable and firm, and integral heat sink is more preferable, to extend motor service life.
In order to achieve the above objectives, the utility model adopts the following technical solutions: a kind of better rotor arrangement of heat dissipation,
Including shaft, pawl pole and fan blade, the fan blade includes frame and blade, and the shaft is equipped with external screw thread, the external screw thread
On be threaded with retainer plate, the fan blade side leans against pawl pole, and the other side is fastened by the retainer plate.
Further, the pawl pole surface is equipped with positioning column, and it is compatible with the positioning column fixed that the fan blade is equipped with
Position hole.
Further, the pawl pole includes mutually matched forward and backward pawl pole.
It further, further include the magnetic field winding being set between forward and backward pawl pole.
Further, the fan blade includes forward and backward fan blade.
Further, the fan blade has three to ten blades, and blade is evenly distributed.
Further, the fan blade has eight equally distributed blades.
Further, the retainer plate is equipped with internal screw thread compatible with the external screw thread.
Further, the fan blade is specially alloy aluminium sheet.
Further, the forward and backward pawl pole includes equally distributed six claws shape magnetic pole.
The setting having the beneficial effect that through fan blade of the utility model, and be fixed with retainer plate, so that fan blade is fixed
Securely, rotor arrangement heat dissipation is more preferable for position.

Fan blade side leans against pawl pole, and the other side is fastened by the retainer plate.It is fixed, makes by the setting of fan blade, and with retainer plate
Fan blade firm position is obtained, rotor arrangement heat dissipation is more preferable.
In the present embodiment, the pawl pole surface is equipped with positioning column 6, and the fan blade is equipped with and is adapted with the positioning column
Location hole 7.By the setting of positioning column and positioning hole, so that fan blade fixation is more stable and firm.
In the present embodiment, the pawl pole includes mutually matched preceding pawl pole 8, rear pawl pole 9.
It further include the magnetic field winding 10 being set between forward and backward pawl pole in the present embodiment.
In the present embodiment, the fan blade includes preceding fan blade 3, rear fan blade 4.By the setting of the double fan blades in front and back, enhance scattered
Thermal effect.
In the present embodiment, the fan blade has three to ten blades, and blade is evenly distributed.
In the present embodiment, the fan blade has eight equally distributed blades.
In the present embodiment, the retainer plate is equipped with internal screw thread 11 compatible with the external screw thread.
In the present embodiment, the fan blade is specially alloy aluminium sheet.
In the present embodiment, the forward and backward pawl pole includes equally distributed six claw shapes magnetic pole 2.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
