Problems solved by technology

[0003] The front end cover and the casing of the existing outer rotor brushless motor are fixed by multiple bolts. The brushless motor will vibrate during operation, and the vibration will cause the bolts to resonate. The rotation direction of the brush motor shaft is the same. After a long time, the bolts will be loosened, and the front cover will be separated from the housing, which will cause damage to the motor. For example, the rotation direction of the bolt is opposite to that of the brushless motor shaft. Down will make the bolts screw tighter, which will cause a squeezing force on the front end cover, which will easily damage the front end cover, and at the same time, it will be more difficult to unscrew

Embodiment 1

[0032] see Figure 1-8 , the present invention provides a technical solution of a brushless motor surrounded by single wires: its structure includes a front cover 100, a body 200, a heat sink 300, and a sealing ring 400, and the body 200 is evenly distributed with heat sinks arranged equidistantly 300, the body 200 is mechanically connected with a front end cover 100, and a sealing ring 400 is attached between the front end cover 100 and the body 200, and the setting of the sealing ring 400 is to improve the airtightness of the installation of the body 200 and the front end cover 100 ;

[0033] The front end cover 100 includes a rotation locking mechanism 101, a translation limit plate 102, a limit clamp column 103, an inner hexagon bolt 104, an adjustment gear 105, a cover body 106, and a rotation gear 107. The center of the cover body 106 An adjustment gear 105 is installed, and the four positive positions of the adjustment gear 105 are engaged with a rotation gear 107, and...

Embodiment 2

[0046] see Figure 1-3 , 8-10, the present invention provides a technical solution of a brushless motor surrounded by single wires: its structure includes a front end cover 100, a body 200, a heat sink 300, and a sealing ring 400, and equidistant patterns are evenly distributed outside the body 200. The provided heat sink 300, the body 200 is mechanically connected with the front end cover 100, and the sealing ring 400 is fitted between the front end cover 100 and the body 200, and the setting of the sealing ring 400 is to improve the tightness of installation;

Abstract

The invention discloses a brushless motor surrounded by a single wire. Its structure includes a front cover, a machine body, a cooling fin and a sealing ring. The cooling fins arranged at equal intervals are evenly distributed outside the machine body. The machine body is mechanically connected with a front cover and a front cover. A sealing ring is fitted between the machine body. Compared with the prior art, the present invention has the beneficial effects of: threaded connection between the hexagonal bolts and the threaded grooves of the front end cover and the threaded holes of the machine body, only using bolts without using The connection between the front end cover and the body can be realized by reaching the nut, and the front end cover adopts a new structure setting, which can hold the bolt horizontally, so as to effectively prevent the hexagonal bolt from loosening or slightly moving in the direction, and can greatly improve the installation of the front end cover and the body. Firmness, effectively prevents the front cover from being separated from the body, avoids damage to the front cover and the motor, and also prevents the hexagon socket bolts from being screwed tighter, so it will not cause extrusion force on the front cover, and has a protective effect on the front cover. The bolts are disassembled Also more convenient.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a brushless motor surrounded by single wires. Background technique [0002] The brushless DC motor is composed of the motor body and the driver. It is a typical mechatronics product. It uses semiconductor switching devices to realize electronic commutation, that is, electronic switching devices are used to replace traditional contact commutators and brushes. High reliability, no reversing sparks, low mechanical noise, etc., are widely used in high-end recording sets, video recorders, electronic instruments and automated office equipment. [0003] The front end cover and the casing of the existing outer rotor brushless motor are fixed by multiple bolts. The brushless motor will vibrate during operation, and the vibration will cause the bolts to resonate. The rotation direction of the brush motor shaft is the same. After a long time, the bolts will be loosened, and the front cover ...
