Abstract
The utility model relates to a flywheel for a magnetic motor rotor and with an improved structure. The flywheel is basically in a shape of a bowl and integrally formed by the bottom and a circular lateral wall, a plurality of protrusions are arranged on an outer wall of the lateral wall, and the inner wall of the lateral wall is a smooth arc surface. The flywheel solves the problem in the prior art that a plurality of pits on the inner wall of the lateral wall causes reduction of magnetic permeability areas and guarantees power of a magnetic motor.
Description
Technical field
The utility model relates to the magnetogenerator technical field, particularly relates to a kind of magneto rotor flywheel that improves structure.
Background technique
Magnetogenerator is the small-sized alternator that produces magnetic field with permanent-magnet steel, is the priming supply in the gasoline engine ignition system.Magneto ignition system is comprised of switch, spark coil, circuit breaker, capacitor, distributor and safe discharge device etc., and it produces high-tension electricity and distributes to the spark plug of each cylinder.Magnetogenerator adopts rotary magnetic steel formula structure mostly, and magnet steel is installed on the rotor, and other each parts are installed on the internal-combustion engine respectively.When magnet steel rotates, primary air induces electromotive force (being called primary potential), generation current (being called primary current) when contact breaker points is closed, when contact breaker points throw open, when cutting off primary current suddenly, secondary winding induces quite high electromotive force (being called secondary electromotive force), makes spark plug sparking.
In the prior art, magneto rotor comprises the flywheel body, is installed in the flywheel several pieces of magnet steel and magnet steel fixing frame with flywheel, the flywheel body is bowl-shape, form integrative-structure by bottom and circular annular sidewall, a plurality of projections are arranged on the sidewall outer wall, be used for providing trigger signal, corresponding many pits are arranged on the sidewall inwall.Its deficiency is: owing on the existing flywheel body sidewall inwall a plurality of pits are arranged, this just causes magnetic conductive area to reduce, and then so that the power of magnetogenerator descends, need to be improved.
Summary of the invention
The utility model aims to provide the magneto rotor flywheel of the larger improvement structure of a kind of magnetic conductive area.
Technical solution of the present utility model is as follows:
A kind of magneto rotor flywheel that improves structure is bowl-shape substantially, forms integrative-structure by bottom and circular annular sidewall, on the described sidewall outer wall a plurality of projections is arranged, and it is characterized in that: described sidewall inwall is smooth arc surface.
Because the sidewall inwall is smooth arc surface, has avoided the deficiency that a plurality of pit magnetic conductive areas reduce in the prior art, magnetic conductive area can not reduce, and has guaranteed the power of magnetogenerator, has realized easily goal of the invention.
Description of drawings
Below with reference to drawings and Examples the utility model is described in further details.
Accompanying drawing 1 is the utility model embodiment's structural representation.
Accompanying drawing 2 is rear view embodiment illustrated in fig. 1.
Accompanying drawing 3 is that A-A embodiment illustrated in fig. 1 is to sectional view.
Each sequence number is respectively among the figure: 1, flywheel; 2, bottom; 3, sidewall; 4, projection.
Embodiment
Referring to accompanying drawing 1,2,3, the magneto rotor of the improvement structure shown in the utility model embodiment is bowl-shape substantially with flywheel 1, forms integrative-structure by bottom 2 and circular annular sidewall 3, have a plurality of protrudingly 4 on the described sidewall outer wall, the sidewall inwall is smooth arc surface.Avoided that the some pits on the sidewall inwall cause reducing of magnetic conductive area in the prior art, guaranteed the power of magnetogenerator, realized easily goal of the invention.
Above-mentioned drawings and Examples only are used for explanation the utility model, and protection domain of the present utility model is not constituted any limitation.
