Abstract
The utility model discloses a special-purpose motor for an electric tool, comprising a rotor and a stator; wherein the rotor comprises a mandrel (1), a fan (2), a rotor winding (4), end plates (5), a rotor core (6), a mandrel bushing (7), and a commutator (8); a protective net cover (3) matched with the rotor winding (4) is sleeved on the rotor winding (4) at a side of the fan (2), the fan (2) is provided with a clamping groove, the protective net cover (3) is provided with a socket, the protective net cover (3) is fixed on the fan (2) through cooperation between the socket and the clamping groove; the stator comprises a stator core (11), a stator winding (9) and a ribbon (10) used for binding the stator winding (9) which are fixed into a whole; and a fusion bonding protection layer is coated on a surface of the stator winding (9). By adopting the above structure, the special-purpose motor of the utility model has the advantages of simple and reasonable structure, convenient production and installation, good heat dissipation effect, good protection effect, long service life, etc.
Description
Technical field
The utility model relates to a kind of motor, the motor of special use on particularly a kind of electric tool.
Background technology
Electric tool because simple in structure, manipulate light and handy, easy to carry, high efficiency; Be widely used in all trades and professions; The quality quality of electric tool depends primarily on the runnability of motor; In electric tool when design, require also that motor volume is little, efficient is high, stable except will considering factors such as profile is small and exquisite, in light weight, power is big.But traditional motor is not because the limitation of technology or processing technology all plays effective protection to stator winding and rotor winding in design; Because work under bad environment; Electric tool adds and can produce the hard thing of a large amount of graininess man-hour workpiece being carried out various forms of operations; Motor produces bigger suction under rotation at a high speed, along with the suction that motor produces enters in the casing, the stator winding and the rotor winding of hard thing of graininess and motor rub, collide with the hard thing of some graininess; Destroy the enamelled wire surface insulation layer or make the enamelled wire fracture; Cause the short circuit of magnet wire insulation layer rent, cause motor damage or cisco unity malfunction, bring very big loss to the user.For this reason, many manufacturers and knowledgeable people develop and manufacture experimently to the problems referred to above, and product emerges but do not find comparatively reasonably so far as yet.
Summary of the invention
In order to overcome the existing existing above-mentioned deficiency of electric tool motor, the purpose of the utility model provide a kind of simple and reasonable, production is easy for installation, protection effect good, the electric tool motor special of long service life.
The utility model solves the problems of the technologies described above the technical scheme that is adopted; It comprises rotor, stator; Described rotor comprises mandrel, fan, rotor winding, end plate, rotor core, mandrel lining, commutator, is arranged with the protection net that is complementary with the rotor winding on the rotor winding of said fan side, and fan is provided with draw-in groove; Protection net is provided with socket, and guard passes through the matching and fixing of socket and draw-in groove on fan.
Described stator comprises stator core, the stator winding that is fixed as one, the silk ribbon that is used for bundling stator winding, the surface-coated clinkering protective layer of stator winding.
After adopting said structure, following advantage and effect are relatively arranged with prior art:
1, owing to the sheathed protection net that is complementary with the rotor winding on the rotor winding of fan side; Neither influence motor radiating; Can intercept the hard thing of graininess that produces in the course of the work again, make the hard thing of graininess can directly not rub with the enamelled wire of rotor winding, collide, insulating barrier breaks or the generation of enamelled wire phenomenon of rupture can to prevent enamelled wire to be bumped afterwards; Protect the rotor winding effectively, can improve the useful life of motor greatly.
2, owing to stator winding surface-coated clinkering protective layer partly, the class of insulation, protection effect and the useful life that can effectively improve stator winding.
