Abstract
The utility model discloses a kind of motor rotor, comprise motor shaft, electromagnetic assembly, left fan blade, right fan blade; Electromagnetic assembly is fixedly connected on motor shaft; Left fan blade is distributed on electromagnetic assembly left side, and right fan blade is distributed on electromagnetic assembly right side; Left fan blade, right fan blade are rectangular configuration in shaft section; The radius R of left fan blade, right fan blade end is not more than 3mm; Further improvement is: the area in left blade shaft cross section is 1.5 ~ 2.0 times of right fan blade.The utility model air quantity is large, good heat dissipation effect.
Description
Technical field
The utility model relates to technical field of motors, is specifically related to motor rotor.
Background technology
The conventional structure of common motor is external stator, built-in rotor.Motor produces certain heat in operation process, if this heat can not be discharged in time will roll up evil, until affect the useful life of motor.The built-in two ends of rotor of prior art motor is respectively equipped with open type blade, and the wind produced when rotating with motor shaft with rotor plays and drives hot cooling effect.But the fan blade of most of motor rotors of prior art is generally pyramidal structure in shaft section, and the air quantity of generation is less.
Summary of the invention
The utility model, for the deficiencies in the prior art, proposes a kind of motor rotor enlarging markedly air quantity, improve the effect that cools.
The utility model is achieved through the following technical solutions technical goal.
Motor rotor, comprises motor shaft, electromagnetic assembly, left fan blade, right fan blade; Described electromagnetic assembly is fixedly connected on motor shaft; Described left fan blade is distributed on electromagnetic assembly left side, and right fan blade is distributed on electromagnetic assembly right side; Its improvements are: described left fan blade, right fan blade are rectangular configuration in shaft section.
In said structure, the radius R of described left fan blade, right fan blade end is not more than 3mm.
In said structure, the area in described left blade shaft cross section is 1.5 ~ 2.0 times of right fan blade.
The utility model compared with prior art, has following good effect:
1, the utility model fan blade is rectangular configuration in shaft section, and the air quantity of generation enlarges markedly than prior art.
2, the radius of the left fan blade of the utility model, right fan blade end is less, and the sectional area of fan blade is larger, and the wind-force of generation is larger.
3, the area in the utility model left blade shaft cross section is 1.5 ~ 2.0 times of right fan blade, forms random turbulence wind, significantly improves the effect that cools.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below with reference to the accompanying drawings and the utility model is described in further detail in conjunction with the embodiments.
Motor rotor shown in the drawings, comprises motor shaft 1, electromagnetic assembly 3, left fan blade 2, right fan blade 4; Electromagnetic assembly 3 is fixedly connected on motor shaft 1; Left fan blade 2 is distributed on electromagnetic assembly 3 left side, and right fan blade 4 is distributed on electromagnetic assembly 3 right side; Left fan blade 2, right fan blade 4 are rectangular configuration in shaft section; The radius R of left fan blade 2, right fan blade 4 end is not more than 3mm; The area of left fan blade 2 shaft section is 1.5 ~ 2.0 times of right fan blade 4.
