Abstract
The utility model discloses an electric generator for a motorcycle, which is composed of a rotor shaft and a rotor. The exterior of the rotor shaft is sheathed with a magnetism isolating shaft sleeve; iron cores are arranged outside the magnetism isolating shaft sleeve at intervals; a groove is arranged between the two iron cores; a permanent magnet is inlaid in the groove. The utility model gets rid of a carbon brush, sliding rings and excitation coils in the prior art and eases the weight of the rotor; the utility model has the advantages of good power generation effect, a low failure rate, long service life, etc.
Description
The utility model relates to a kind of motor alternator for vehicle, belongs to the technical field of generators of motorcycle special use.
Existing motor generator, with 280 types is example, all have magnet exciting coil and slip ring on its rotor, the weight of rotor is increased, in high speed rotating, very easily make the bearing wear of generator amature and generator bent axle connection place, cause rotor to sweep the boring magnet exciting coil and blow, to whole rotor is scrapped.Because existing generator all has carbon brush and slip ring.This has not only increased the failure rate of generator, and rotor and slip ring all are to link together by soldering or the luxurious mode that connects usually, when rotor high-speed rotated, the friction of carbon brush and slip ring produced high temperature, the junction of rotor and slip ring is very easily snapped, become flexible, cause the damage of rotor.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art and provides inlays permanent magnet between a kind of two iron cores, do not have carbon brush and slip ring, and it is effective to generate electricity, the motor alternator for vehicle that failure rate is low.
The purpose of this utility model is achieved in that it is made of armature spindle, rotor.Its structural feature is, its armature spindle is with outward every the magnetic axis cover, at interval iron core is housed every the magnetic axis cover is outside, and the middle part of two iron cores is provided with groove, is inlaid with permanent magnet in the groove.
Purpose of the present invention can also reach by following technical measures: iron core is flat and is welded on the axle sleeve, and iron core and permanent magnet are embedded as a whole.
The utility model has the advantages that compared to existing technology:
1, removed carbon brush and slip ring, removed the magnet exciting coil of rotor again, greatly alleviated the weight of rotor, the 1.1kg by original reduces to 0.83kg.
2, the generator failure rate is low, the long service life of bearing.
3, structural design is simple, no slot wedge, and scientific arrangement is reasonable, is suitable for suitability for industrialized production.
The explanation of accompanying drawing drawing:
Accompanying drawing is the utility model structural representation.
Below in conjunction with drawings and Examples in detail the utility model is described in detail.
The utility model is the generator of motorcycle special use, is to the improvement of motor generator being arranged, being made of armature spindle (4), rotor.Rotor is made up of permanent magnet (1), iron core (2).Its concrete structure is: the outside suit of armature spindle (4) is every magnetic axis cover (3), go up the interval every magnetic axis cover (3) and welding iron core (2), iron core (2) is flat bar, the middle part of two iron cores (2) is provided with in groove (5), the groove (5) is inlaying permanent magnet (5), and permanent magnet (5) is embedded as a whole with iron core and constitutes rotor jointly.Permanent magnet (5) adopts NdFeB material.
Operation principle of the present utility model: after generator starts, drive the rotation of rotor and armature spindle (4), cutting magnetic line produces induced current, finishes the transfer process of magnetoelectricity.
Claims (3)
1, a kind of motor alternator for vehicle is made of armature spindle, rotor, it is characterized in that its armature spindle is with every the magnetic axis cover outward, every the outside interval of magnetic axis cover iron core is housed, and the middle part of two iron cores is provided with groove, is inlaid with permanent magnet in the groove.
2, motor alternator for vehicle according to claim 1 is characterized in that iron core is flat and is welded on the axle sleeve.
