Abstract

The utility model relates to a brushless motor assembly structure. The existing brushless motor with an outer rotor is not provided with a shell, a bearing at the middle part and a bearing at the end face are fixed on a central shaft, and the other end of the motor cannot be installed and applied because the rotor needs to rotate. And the current motor can only realize that the lead wire and the output shaft are on the same side, and can not realize the application requirement that the lead wire and the output shaft are not on the same side. The utility model discloses a shell sets up rotor, stator and center pin in the shell, the one end of center pin is passed through first bearing and aluminium support installation location, and the other end is fixed a position through the second bearing that sets up tip in the shell, the shell fixed with the aluminium support installation. And the middle part of the central shaft is provided with a third bearing for positioning. The utility model discloses an increase behind the shell, become a traditional inner rotor motor structure with the motor, prevent that operating personnel's hand from touching the rotor injured, promote the security, make outer rotor brushless motor realize that two terminal surfaces are all installable and applicable.

Description

Brushless motor assembly structure

Technical Field

The utility model relates to a brushless motor assembly structure.

Background

The existing brushless motor with an outer rotor is not provided with a shell, a bearing at the middle part and a bearing at the end face are fixed on a central shaft, and the other end of the motor cannot be installed and applied because the rotor needs to rotate. And the current motor can only realize that the lead wire and the output shaft are on the same side, and can not realize the application requirement that the lead wire and the output shaft are not on the same side. When the motor runs, the rotor easily touches the hands of an operator, so that the risk of easy injury exists.

SUMMERY OF THE UTILITY MODEL

The defect to prior art existence, the utility model provides a brushless motor assembly structure makes outer rotor brushless motor increase a shell, and the location installation is reliable, and simple to operate avoids the injury.

Therefore, the utility model adopts the following technical scheme: the brushless motor assembly structure is characterized by comprising a shell, wherein a rotor, a stator and a central shaft are arranged in the shell, one end of the central shaft is positioned through a first bearing and an aluminum support, the other end of the central shaft is positioned through a second bearing arranged at the inner end part of the shell, and the shell is fixedly arranged with the aluminum support.

And the middle part of the central shaft is provided with a third bearing for positioning.

The output end of the central shaft and the outgoing line of the motor are respectively positioned at the two ends of the shell.

The utility model discloses following beneficial effect has:

1. after increasing the shell, become a traditional inner rotor motor structure with the motor, prevent that operating personnel's hand from touching the rotor injured, promote the security, make outer rotor brushless motor realize that two terminal surfaces all can install and use.

2. The two ends of the motor are respectively fixed through the bearings, the stability of the whole structure is improved, and the middle of the motor can be selectively added with another bearing structure for strengthening connection according to needs.

3. The requirement of the outgoing line (three-phase lead and signal line) and the output shaft on the occasion of not being at the same end can be realized.

Fig. 2 is a schematic cross-sectional view of the present invention.

Fig. 3 is a schematic structural diagram of the housing of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

A brushless motor assembly structure as shown in fig. 1-3, comprising a housing 4, a rotor 9, a stator 8 and a central shaft 6 arranged in the housing, one end of the central shaft is fixed and positioned by a first bearing 2 and an aluminum bracket 3, the other end is fixed and positioned by a second bearing 7 arranged at the inner end of the housing, and the housing and the aluminum bracket are fixed and fixed.

The middle part of the central shaft is provided with a third bearing positioning 5. The output end of the central shaft and the outgoing line of the motor are respectively positioned at the two ends of the shell.

The utility model discloses an increase behind the shell, become a traditional inner rotor motor structure with the motor, prevent that operating personnel's hand from touching the rotor injured, promote the security, make outer rotor brushless motor realize that two terminal surfaces are all installable and applicable. The two ends of the motor are respectively fixed through the bearings, the stability of the whole structure is improved, and the middle of the motor can be selectively added with another bearing structure for strengthening connection according to needs. The requirement that the outgoing line (the three-phase lead 1 and the signal line 11) and the output shaft 10 are not at the same end can be met.

The above description is only an example of the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
