Self-radiating motor

A self-heating, motor shaft technology, applied in the direction of electrical components, electromechanical devices, electric components, etc., can solve the problems of poor heat dissipation, components in a relatively harsh working environment, and cannot meet the self-heating of the same motor, so as to meet the heat dissipation requirements. Better self-dissipation effect and lower temperature effect

Problems solved by technology

[0003] In response to this problem, someone has designed a fan by adding a fan to the motor product, and using the fan to blow the motor to cool down. This solution has a cooling effect on the motor to a certain extent, but its heat dissipation effect is poor. The temperature is still high, resulting in the components inside the motor are still in a harsh working environment
In addition, in the existing motors with self-cooling function, the fan can only blow air toward the inside of the motor when the motor shaft is rotating forward or reversely, so it cannot satisfy the requirement of self-radiation for both forward and reverse rotation of the same motor

Embodiment Construction

[0043] See Figure 1 to Figure 5 As shown, it shows the specific structure of the preferred embodiment of the present invention, including a housing 10 , a stator 20 , a rotor 30 , a motor shaft 40 , fan blades 50 and a circuit board 60 . The internal structure and working principle of the motor are not the innovation of this case, so I won’t repeat them here.

[0044] Wherein, the housing 10 is sleeved on the aforementioned motor shaft 40 and rotates with the motor shaft 40; the housing 10 has an end cover 11, and the end cover 11 is formed with a sleeve portion 111 outward along the direction of the motor shaft 40, and A block 1111 protrudes from the outer peripheral side of the sleeve portion 111 , and, corresponding to the position of each guide groove 53 of the fan blade 50 described below, a third cooling hole 112 is opened on the end cover 11 to facilitate air flow out of the casing 10 .

[0045] The fan blade 50 is a fan blade 50 capable of drawing air from the inside...

Abstract

The invention discloses a self-radiating motor. The self-radiating motor comprises a shell, a stator, a rotor and a motor rotation shaft, wherein the shell is provided with an end cover; a fan blade for outwardly sucking air from the interior of the shell is sleeved outside the end cover; the fan blade rotates with the motor rotation shaft; and a heat radiating hole favorable for air to flow out of the shell is arranged on the end cover, corresponding to the position of the fan blade. Therefore, air is actively sucked out from the interior of the motor by the fan blade for outwardly sucking air from the interior of the shell. Compared with the self-radiating motor with the fan blade for blowing air towards the interior of the motor in the prior art, the self-radiating effect is better; heat of the motor can be taken away more quickly to reduce the temperature of the motor, so that the self-radiating motor can be applied to environments with higher temperature, therefore, the application range of the motor is further expanded; and better working performance and longer service life of the motor are also facilitated to be maintained at the same time.

Description

technical field [0001] The invention relates to the technology in the field of motors, in particular to a self-radiating motor. Background technique [0002] At present, motors are widely used in electronics and automation equipment industries. During the operation of the motor, the heat generated will continue to accumulate with the growth of future time, which will gradually increase the temperature inside the motor, which will affect the performance of the internal parts of the motor and have a great impact on the service life of each part. [0003] In response to this problem, someone has designed a fan by adding a fan to the motor product, and using the fan to blow the motor to cool down. This solution has a cooling effect on the motor to a certain extent, but its heat dissipation effect is poor. The temperature is still high, resulting in the components inside the motor are still in a relatively harsh working environment. In addition, the fan of the existing motor wi...
