Abstract

The invention relates to a direct-drive electric tool, which comprises a shell. An electric mechanism is arranged in the shell. The electric tool also comprises a low-speed brushless motor, and an output shaft of the brushless motor is connected with a drive end of an actuating mechanism of the electric tool. The direct-drive electric tool has the advantages that the occupied space, the weight and the noise can be reduced, and the service life can be prolonged.

Description

Direct-drive electric tool
Technical field
The present invention relates to a kind of electric tool.
Background technology
Existing electric tool, type of drive is that motor drives, and motor adopts string pole motor usually, the rotating speed of described drive motors is very high, need reducing gear to coordinate, usually adopt gear reduction, the output shaft of described gear reduction is connected with the drive end of the executing agency of electric tool.The technological deficiency existed: take up room comparatively large, body weight is comparatively large, and noise is comparatively large, and service life is shorter.
Summary of the invention
Comparatively large in order to overcome taking up room of existing electric tool, body weight is comparatively large, and noise is comparatively large, the deficiency that service life is shorter, the invention provides a kind of minimizing and takes up room compared with, the Direct-drive electric tool that reduces body weight, reduce noise, increase the service life.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of Direct-drive electric tool, comprises shell, and install motor drive mechanism in described shell, described electric tool also comprises slow-revving brushless electric machine, and the output shaft of described brushless electric machine is connected with the drive end of the executing agency of described electric tool.
Further, described brushless electric machine is high-density power brushless electric machine.
Further again, electric machine controller is connected with described brushless electric machine, and described electric machine controller is arranged on the side or below of described brushless electric machine.
In the present invention, the executing agency of electric tool refers to the mechanism realizing different operating, the polishing assembly etc. of such as electric angle grinder.
Beneficial effect of the present invention is mainly manifested in: reduce taking up room comparatively, reduce body weight, reduce noise, increase the service life.
Accompanying drawing explanation
Fig. 1 is a kind of schematic diagram of Direct-drive electric tool.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
With reference to Fig. 1, a kind of Direct-drive electric tool, comprises shell 1, and install motor drive mechanism in described shell 1, described electric tool also comprises slow-revving brushless electric machine 2, and the output shaft of described brushless electric machine 2 is connected with the drive end of the executing agency of described electric tool.
Further, described brushless electric machine 2 is high-density power brushless electric machine.
Electric machine controller 3 is connected with described brushless electric machine 2, and described electric machine controller is arranged on the side or below of described brushless electric machine 2.
High-density power brushless electric machine in the present embodiment has following characteristics: efficiency is high, and electric efficiency is more than 80%; Complete machine long service life, because do not have carbon brush and gear, with the life-span more than 1200 hours; Noise is low at about 65db; One of volume is little, lightweight four; There is overcurrent protection and prominent calling protection.
The electric tool of the present embodiment comprises electric angle grinder, Handheld electric circular saw, hand-hold shearing unit, and the electric tool of other types.
