Abstract
The utility model discloses a new-type brushless generator, which is matched to be used on the motor cars and tractor. The inner stator which is not fixed on the rear end cover is fixed on the front end cover. A blade wheel is arranged between the rear end cover and the rotor, and one end leader line of the exciting coil is connected with the securing screw which is on a data plate which is used as a metal conductor. The new-type brushless generator with the built-in blade wheel has the advantages of good heat dissipation condition and high horse power and can improve the output current of the generator remarkably.
Description
The utility model proposes a kind of novel brushless generator, it is a matching used generator on automobile and tractor.
At present, automobile and the tractor generators that can export big electric current mostly are to adopt the form that brush is arranged, this generator that brush arranged often loses circle because of carbon brush, collector ring wearing and tearing and produces the arcing phenomenon of burning in the process of using, therefore this generator ratio is easier to break down, have influence on the performance of generator to a certain extent, make maintenance work increase some difficulties.Though automotive brushless generator commonly used has advantage of simple structure, but the internal stator of this automotive brushless generator commonly used is to be fixed on the rear end cap, when the time of the big electric current of output is longer, because generator inner ventilation radiating condition is poor, superheating phenomenon appears in coil easily, limited the maximum output current of generator so to a certain extent, made this generator not satisfy actual needs.
Task of the present utility model provides a kind of novel brushless generator that can export big electric current, and its ventilation and heat condition is good, can normally work under the environmental condition condition of severe.
Task of the present utility model is finished as follows, this novel brushless generator structurally has tangible difference part with traditional brushless generator, the internal stator that is it is not to be fixed on the rear end cap, but be fixed on the front end housing, this structure makes generator compacter, and between rear end cap and rotor, reserved a locus, a fan blade can be installed on this empty position, this fan blade is to be fixed on fore paw one side of rotor assembly, generator since interior dress so a fan blade its inner ventilation and heat condition is significantly improved, can improve the output current of generator so widely.In addition, this brushless generator magnet exciting coil one end lead-out wire is received on the iron core of internal stator, other end lead-out wire is then received near the shell of generator the nameplate, this lead-out wire that thoroughly does away with edge be with nameplate on be connected mutually near a trip bolt of front end housing, nameplate is a metallic conductor, it draws a part of lead as magnet exciting coil one end, isolate with insulation spacer between the shell of nameplate and generator, picking out an insulated conductors near on another trip bolt of rear end cap on the nameplate.This thoroughly does away with edge lead is that voltage regulator end line with generator links.
This novel brushless generator, its topology layout is reasonable, and the ventilation and heat condition is good, this generator is owing to be equiped with two fan blades, fan blade of original installing adds an inbuilt fan blade again outside now, and therefore the output current of this generator can improve greatly.
Below in conjunction with accompanying drawing the utility model is described in further detail.
Figure is a complete machine structure figure of the present utility model.
As can be seen from the figure, in this novel automotive brushless generator, its internal stator (1) is to be fixed on the front end housing (2), each parts of generator are arranged quite compactly, can install a fan blade (3) in the inside of generator like this, this fan blade (3) is placed in the neutral place between rear end cap (4) and the rotor assembly (5), and it is to be fastened on the pawl utmost point (6) one sides of rotor assembly (5).When the rotor of generator when rotated, inbuilt fan blade (3) is also followed rotation, has improved the radiating condition of generator inside, superheating phenomenon can not take place and has influence on the operate as normal of generator in coil when making generator export big electric current.One end lead-out wire of the magnet exciting coil (7) in the internal stator (1) is connected on the iron core of internal stator (1), its other end insulation lead-out wire is to be connected on nameplate (8) to go up near on the trip bolt (9) of front end housing (2), nameplate (8) is on the shell (10) that is axially fixed in generator, nameplate (8) is the important component part that magnet exciting coil (7) is drawn lead, trip bolt (9) and (11) at nameplate (8) two ends all will use insulation spacer (12) to isolate, make nameplate (8) and trip bolt (9) thereof, (11) with shell (10) mutually insulated of generator, from drawing an insulated conductor near the trip bolt (11) of rear end cap (4), this root lead is that the end line with voltage regulator (13) joins.
The automotive brushless generator of this new structure, it is good to have a radiating condition, and bigger than merit, the life-span is long, few easy workout part, advantage such as overload capacity is strong, the output current of this brushless generator improves significantly.
