Abstract
The invention relates to a motor rotor with fan blades. The motor rotor with the fan blades comprises a rotating shaft (1), the diameter of each of two ends of the rotating shaft (1) is smaller than the diameter of the intermediate section, a plurality of rotor cores (2) uniformly sleeve the intermediate section of the rotating shaft (1) at intervals, a circle of vent holes are distributed in the inner cavity of each rotor core (2) along the circumferential direction, the fan blade (3) sleeves each intermediate section between two rotor cores (2), each fan blade (3) comprises a fixed sleeve and a blade, the fixed sleeve is a circular ring, and a plurality of blades are distributed in the outer circle of the fixed sleeve in an equal-radian mode. According to the motor rotor with the fan blades, through arranging the fan blade on the motor rotor, air flowing from the vent holes of the rotor cores directly cools the rotor cores, and the cooling effect is good. The fan is simple in structure, convenient to process and produce, easy to assemble, low in fault rate and good in application value.
Description
Technical field
The invention belongs to technical field of motors, particularly relate to a kind of rotor with fan leaf.
Background technology
The stator coil of AC magnetoelectric machine has impedance, can produce a large amount of heat when passing into alternating current; And the electric current passing into alternation can produce the magnetic field of alternation, rotor can form eddy current effect on magnet steel surface when running up, and also can produce heat.Motor internal will produce very high heat in this case, if do not taken effective measures, these heats are discharged, magnet steel can be easy to demagnetize because of overheated, and this demagnetization is irreversible greatly, and causes motor to get a desired effect.
In existing technology, fan is fixed on the afterbody of motor more.Namely want specialized designs space to fix fan at the afterbody of motor, and power to separately fan external power supply.Also need a deep bead simultaneously, ensure that fan blows wind energy enough air channels from housing stream flows through smoothly.
It is fan design installing space that existing technology needs specially, and add the design cycle, volume and the length of motor too increase, and also need to buy a fan specially, add the cost of motor.Fan also has requirement on installation is fixed and be dust-proof, if improper use can cause dust to enter the normal operation affecting motor, also can bring the series of problems such as vibration and noise.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of rotor with fan leaf, complicated to solve existing fan design, the problem that the life-span is not grown.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of rotor with fan leaf, comprise rotating shaft, rotating shaft two ends diameter is less than the diameter of interlude, described rotating shaft interlude equidistantly overlaps and has several rotor cores, be distributed with a circle ventilation hole along its circumference in rotor core inner chamber, on rotor core interlude between any two, cover has fan leaf, and fan leaf comprises fixed cover and blade, fixed cover is an annulus, and the first-class arc minutes of fixed cover cylindrical is furnished with some blades.
Described rotor core is overlapped to form by some magnetic links.
Described spindle central has through hole.
Beneficial effect
The present invention is by carrying a fan leaf on rotor, from the air that the ventilation hole of rotor core flows, directly cools rotor core, has good cooling effect.The result of this fan is simple, and processing is convenient, and assembling is also very simple, and the failure rate of appearance is also very low, has good using value.

Embodiment
Below in conjunction with specific embodiment, set forth the present invention further.Should be understood that these embodiments are only not used in for illustration of the present invention to limit the scope of the invention.In addition should be understood that those skilled in the art can make various changes or modifications the present invention, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the present invention's instruction.
Embodiment 1
As shown in Figure 1 to 4, a kind of rotor with fan leaf, the epitrochanterian rotor core 2 carrying fan has several ventilation holes, when the rotating shaft 1 of motor is rotary, fan leaf 3 also can along with rotating together, and cold air can the ventilation hole of rotor core 2 from behind enter, flow out from the ventilation hole of rotor core 2 above again, form a centrifugal fan, thus the flowing of the air of rotor driven iron core 2 inside, the enforceable heat by motor internal is taken away.Like this rotor core is directly cooled, substantially increase the air cooling effect of permanent magnetic electric machine rotor iron core, ensure that the reliability of magneto continuous firing, improve the operating efficiency of motor.
Carry the rotor of fan, cold air can enter from the rear end of stator core when rotated, then discharges from the front end of stator core, and directly cool stator core and magnet steel, air cooling effect is good.The fan of the design be direct shrink-on in rotating shaft, do not need specialized designs space, shorten the design cycle, simplify electric machine structure, the volume of less motor and length.The structure of the fan of the design is simple simultaneously, greatly reduces motor cost.
Claims (3)
1. the rotor with fan leaf, comprise rotating shaft (1), rotating shaft (1) two ends diameter is less than the diameter of interlude, it is characterized in that: described rotating shaft (1) interlude equidistantly overlaps and has several rotor cores (2), a circle ventilation hole is distributed with along its circumference in rotor core (2) inner chamber, on rotor core (2) interlude between any two, cover has fan leaf (3), fan leaf (3) comprises fixed cover and blade, fixed cover is an annulus, and the first-class arc minutes of fixed cover cylindrical is furnished with some blades.
