Abstract
The utility model relates to a DC (Direct Current) brushless electric tool which comprises a main body and a handle, wherein a cable is arranged at the tail part of the handle; a power panel and a switch are arranged in the middle of the handle; a DC brushless controller capable of supplying power to a stator under the control of the switch is arranged on the main body; the stator is matched with a rotor through a position transducer; and the rotor is connected with a rotating clamp through a gear box. The DC brushless electric tool, which is not provided with a carbon brush and an armature, is free from the problems of commutation spark, high noise, strong electromagnetic interference and the like, and has a long service life, high efficiency, and high intelligence owing to the adoption of the DC brushless controller.
Description
Technical field
The utility model relates to a kind of electric tool, especially a kind of brush DC electric tool.
Background technology
Present electric tool all is single-phase series excitation form operation principle, is mainly hand-held, light and handy, safety, convenience, wide, so demand is big.Yet single-phase series excitation electric tool has many deficiencies, mainly contains commutation spark, and noise is big, and electromagnetic interference is big, often changes carbon brush and carbon brush dust and overflows, and armature is perishable.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned prior art, and a kind of long service life is provided, the brush DC electric tool that efficient is high.
The utility model solves the technical scheme that its technical problem adopts: this brush DC electric tool, comprise fuselage, handle, the handle afterbody is provided with cable, the handle middle part is provided with power panel and switch, fuselage is provided with the brush DC controller that can send electricity by switch control to stator, stator cooperates with rotor by position sensor, and rotor is connected with by gearbox changes folder.
As preferably, be connected with the fan blade that can dispel the heat to brush DC controller and stator on the rotor.
As preferably, described cable comprises cable and sheath.
Problems such as the effect that the utility model is useful is: the utility model is not because of having carbon brush and armature, so there is not commutation spark, noise is big, and electromagnetic interference is big, its long service life, the efficient height is with brush DC controller ' s intellectualization height.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Description of reference numerals: fuselage 1, handle 2, brush DC controller 3, position sensor 4, cable 5, cable 5-1, sheath 5-2, switch 6, power panel 7, rotor 8 changes folder 9, gearbox 10, stator 11, fan blade 12.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
Embodiment: as Fig. 1, this brush DC electric tool, comprise fuselage 1, handle 2, handle 2 afterbodys are provided with cable 5, cable 5 comprises cable 5-1 and sheath 5-2, handle 2 middle parts are provided with power panel 7 and switch 6, fuselage 1 is provided with the brush DC controller 3 that can send electricity by switch 6 controls to stator 11, brush DC controller 3 obtains the instruction of switch 6, by the velocity attitude pattern that configures stator 11 is sent, stator 11 cooperates with rotor 8 by position sensor 4, rotate for stator 11 respective direction Control of Voltage rotors 8 according to position sensor 4 information, be connected with the fan blade 12 that can dispel the heat to brush DC controller 3 and stator 11 on the rotor 8, rotor 8 drives by gearbox 10 reductions of speed to be changeed folder 9 and carries out work.Wherein brush DC controller 3 can add the various control pattern as required, as constant torque, and constant rotational speed, overload protection, overtemperature protection, rotating is set, and status display function.
This brush DC electric tool can apply in the different instruments, as percussion drill, and electric drill, electric hammer, electric planer, cutting machine, bakelite mills, metope groover, angle grinding machine etc.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
