Embodiment 1

[0045] see Figure 1 to Figure 10 As shown, the present application proposes a motor 100 , including: a motor housing 120 , a motor main body 110 mounted on the motor housing 120 , a moving impeller 130 and a windshield 140 . The inside of the motor housing 120 is hollow to form a first accommodating cavity 1211 . In order to facilitate the installation of the motor body 110 to the motor housing 120, the motor housing 120 includes a main housing 121 and a rear cover 122. The main housing 121 is hollow inside and has an opening at the bottom. The rear cover 122 is detachably covered on the main housing. The bottom opening of the housing 121 forms a first accommodating cavity 1211 . Therefore, when installing the motor main body 110 , after the rear cover 122 is removed from the main housing 121 , the motor main body 110 can be conveniently installed on the main housing 121 . The motor body 110 includes a rotating shaft 111 which is rotated on the motor housing 120, a rotor 11...

Embodiment 2

[0060] Example 2, please refer to Figures 11 to 15 , the difference from the first embodiment is that the outer cover 150 is not provided, and the wind cover 140a directly covers the moving impeller 130a and the fixed impeller 160a, that is, all the impellers are covered by the wind cover 140a, and the wind cover 140a is directly connected to the motor housing 120a. Correspondingly, the arrangement form and position of the heat dissipation channels have changed. In this embodiment, the heat dissipation channel is the air channel 1212a.

[0061] Specifically, the second accommodating cavity 141a is formed with a first air inlet 142a on the side of the hood 140a away from the motor housing 120a, and the second accommodating cavity 141a is formed on the other side of the hood 140a close to the motor housing 120a A first air outlet 143a is formed on one side, and the first air outlet 143a is used to connect with the annular support frame 1213a of the motor housing 120a. In this...

Embodiment 3

[0065] Embodiment three, please refer to Figure 16 and Figure 17 The difference from Embodiment 1 is that no cover 150 is provided, and the wind cover 140b directly covers the moving impeller 130b and the fixed impeller 160b, that is, all impellers are covered by the wind cover 140b, and the wind cover 140b is directly connected to the motor housing 120b. Specifically, the second accommodating chamber 141b is formed with a first air inlet 142b on the side of the windshield 140b away from the motor casing 120b, and the second accommodating chamber 141b is formed on the other side of the windshield 140b close to the motor casing 120b. A first air outlet 143b is formed on one side, and the first air outlet 143b is used to connect with the annular support frame 1213b of the motor housing 120b. Specifically, the first air outlet 143b is clamped or interfered with the motor housing 120b connect.

[0066] The cooling air duct in this embodiment is composed of the air flow duct 12...

Abstract

The present application discloses a motor, comprising: a motor housing, the interior of which is hollow to form a first accommodating chamber, the motor housing is provided with an annular support frame, and the annular support frame is arranged around the circumference of the motor housing. The outer side of the motor casing; the fixed impeller is detachably arranged on the side of the motor casing close to the annular support frame and is clamped with the annular support frame; the wind cover is in contact with the fixed impeller, and the inside of the wind cover is hollow to form a The second accommodating chamber; the movable impeller is arranged in the second accommodating chamber; the outer cover is sleeved on the outer peripheral surface of the windshield and clamped with the annular support frame; and the motor main body is arranged in the motor housing and partially extended The first accommodation chamber is connected with the moving impeller; wherein, the motor is also provided with a heat dissipation channel communicating with the first accommodation chamber and the second accommodation chamber, and the motor housing is provided with a second passage communicating with the first accommodation chamber. One air inlet. Through the above method, the present application has the advantage of good heat dissipation effect.

Description

technical field [0001] The present application relates to the technical field of motors, in particular to brushless motors. Background technique [0002] A motor is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. DC motors can be divided according to their structure and working principle: brushless DC motors and brushed DC motors. Although the development time of brushless motors in our country is short, it has developed rapidly with the increasing maturity and perfection of technology. It has been widely used in many fields such as model aircraft, medical equipment, household appliances, electric vehicles, etc. However, due to the poor heat dissipation effect of traditional motors, the internal temperature of the motor rises, which affects the performance of the motor. Contents of the invention [0003] In view of the deficiencies in the above technologies, the present application provides a motor...
