Embodiment Construction

[0009] exist figure 1 Among them, the brushless Hall external DC motor includes a casing 1, a stator 2, an inner rotor 3, a bearing I 4, a motor shaft 5, a Hall element 6, a rear cover 7, an air impeller 8, an outer rotor 9, and a bearing II 10 , the motor shaft 5 fixes the inner rotor 3 in the space surrounded by the stator 2 through the bearing I 4 and the bearing II 10, an outer rotor 9 is arranged on the motor shaft 5 outside the stator 2, and a Hall element is correspondingly installed above the outer rotor 9 6. One end of the motor shaft 5 outside the casing 1 is connected to the wind impeller 8, and the outside of the Hall element 6, the outer rotor 9 and the wind impeller 8 is connected to a rear cover 7, and the rear cover 7 plays a role of protecting internal components. When in use, because the Hall element 6 is placed outside, the heat is reduced, reducing the frequency of the Hall element 6 being burned out, and when dismantling and repairing, only need to open...

Abstract

The invention relates to a brushless Hall externally built direct current motor. An outer rotor is arranged on a motor shaft outside a stator, a Hall component is correspondingly arranged above the outer rotor, a fan blade wheel is connected with the motor shaft, at one end of the exterior of an outer shell, the end of the motor shaft is arranged outside an outer shell, rear outer covers are connected with the outside of the Hall component, the outer rotor and the fan wheel, and the rear outer cover has the function of protecting an inner component. Not only be the motor can convenient to disassemble and repair, but also burning-out rate of the Hall component can be reduced and service life of the motor is prolonged. The brushless Hall externally built direct current motor is simple in structure, and brings great convenience to consumers and maintenance workers.

Description

technical field [0001] The invention relates to a novel motor, in particular to a brushless Hall external DC motor. Background technique [0002] At present, the stator coils of the known motors all need to be connected to the Hall film, but when the Hall film in the motor is burned or other faults occur, the motor cannot work normally, which makes the work of dismantling and repairing the motor more troublesome and time-consuming. Moreover, the sealing performance of the motor after being dismantled and repaired by the maintenance personnel is often not as good as the sealing performance of the factory, thus affecting the service life of the motor. Contents of the invention [0003] In order to solve the problem that the existing motor Hall is inconvenient to disassemble and repair, the present invention provides a brushless Hall external DC motor. The brushless Hall external DC motor can not only facilitate the disassembly and repair of the motor, but also reduce the Th...
