Embodiment 1

[0024] figure 1 with figure 2 It shows the first embodiment of the negative pressure heat dissipation motor of the present invention, including a casing 1, a motor main shaft 2, a shaft support group 3, a rotor 4 and a stator 5, and the motor main shaft 2 is installed in the casing 1 through the shaft support group 3 , the rotor 4 is installed on the motor shaft 2, the stator 5 is installed in the casing 1 and sleeved on the periphery of the rotor 4, the casing 1 is provided with an air inlet 11 and a negative pressure pipe 6 for leading out the air flow inside the casing 1. When the motor is running, the motor main shaft 2 is used to drive the rotor 4 to rotate, and the external low-temperature air enters the casing 1 from the air inlet 11 to air-cool the motor main shaft 2, the shaft support group 3, the rotor 4 and the stator 5, and the heat after heat exchange Air is discharged from negative pressure pipeline 6. Compared with the traditional structure, the heat dissipat...

Embodiment 2

[0032] image 3 Shown is the second embodiment of the negative pressure heat dissipation motor of the present invention, the heat dissipation motor is basically the same as Embodiment 1, the only difference is that in this embodiment, the air inlet 11 is arranged at the bottom of the casing 1, and the air outlet 12 is arranged In the first quadrant area or the second quadrant area of ​​the cabinet 1. That is to say, the exhaust mode of the upper side is formed, which can also ensure the optimization of the heat exchange space.

Abstract

The invention discloses a negative-pressure heat dissipation motor, which comprises a casing, a motor main shaft, a shaft supporting group, a rotor and a stator, and is characterized in that the motormain shaft is mounted in the casing through the shaft supporting group, the rotor is mounted on the motor main shaft, the stator is mounted in the casing and sleeves the periphery of the rotor, and the casing is provided with an air inlet and a negative pressure pipeline for guiding out air flow in the casing. The heat dissipation motor has the advantages of being simple and compact in structure,low in cost, long in service life and capable of improving heat dissipation efficiency.

Description

technical field [0001] The invention relates to motor heat dissipation technology, in particular to a negative pressure heat dissipation motor. Background technique [0002] The motor generally adopts the IC411 heat dissipation method, which is the natural cooling of the motor. The cooling method of the motor is divided into fully enclosed external axial self-fan cooling, that is, the motor itself is cooled by its own fan, and no external power supply is required for cooling. [0003] The motor self-fan dissipates heat to the casing, and the heat dissipation efficiency is low. In addition, the length of the motor self-fan makes the body larger, which is not conducive to the transportation and installation of the motor in a limited space. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a negative pressure heat dissipation motor with simple and compact cost structure, ...
