Abstract
A direct-drive electric tool comprises a shell. An electric mechanism is mounted in the shell. The direct-drive electric tool further comprises a low-revolution-speed brushless motor, and an output shaft of the brushless motor is connected with a driving end of an executing mechanism of the electric tool. Occupation space and weight are decreased, noise is reduced, and the service life of the direct-drive electric tool is prolonged.
Description
Technical field
The utility model relates to a kind of electric tool.
Background technology
Existing electric tool, type of drive are motor-driven, and motor adopts string utmost point 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 that exists: take up room larger, body weight is larger, and noise is larger, and service life is shorter.
Summary of the invention
Larger in order to overcome taking up room of existing electric tool, body weight is larger, and noise is larger, the deficiency that service life is shorter, the direct-driving electric power driven tools that the utility model provides a kind of minimizing to take up room, reduce body weight, reduce noise, increase the service life.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of direct-driving electric power driven tools comprises shell, and motor drive mechanism is installed in described shell, and 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 the 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 side or the back of described brushless electric machine.
In the present invention, the executing agency of electric tool refers to realize the mechanism of different operating, such as polishing assembly of electric angle grinder etc.
The beneficial effects of the utility model are mainly manifested in: minimizing takes up room, reduces body weight, reduces noise, increases the service life.
Description of drawings
Fig. 1 is a kind of schematic diagram of direct-driving electric power driven tools.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1, a kind of direct-driving electric power driven tools comprises shell 1, the interior installation motor drive mechanism of described shell 1, and described electric tool also comprises slow-revving brushless electric machine 2, 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 the 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 side or the back of described brushless electric machine 2.
High-density power brushless electric machine in the present embodiment has following characteristics: efficient is high, and electric efficiency is more than 80%; The complete machine long service life because there is no carbon brush and gear, uses the life-span more than 1200 hours; Noise hangs down in the 65db left and right; One of volume is little, lightweight four; Have 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.
