Abstract
The utility model relates to a permanent magnetic AC generator, in which disk magnet rings with different polarities are pasted on the inner sides of the left claw pole and the right claw pole; sectormagnet rings are distributed uniformly on the back of the claw poles; circular ring iron yokes with good magnetic conductivity are respectively clamped between the claw poles; and magnetism separating shaft sleeves are installed between the claw pole shaft holes and the rotating shafts. By canceling the structures of electric exciting coil, brush, slip ring and two solid iron yokes with axial magnetic conductive function, The utility model reduces the weight of the rotor greatly; has the advantages of high specific power, oil saving, energy saving, easy assembling, low cost, more reliable running, low maintenance amount, has no spark and dust caused by slip ring and carbon brush, and is beneficial to environmental protection. So, the utility model is an ideal novel permanent magnetic AC generator.
Description
Technical field
The utility model belongs to the vehicle alternator technical field, relates in particular to a kind of novel permanent magnetic alternating current generator that can be used for motor vehicle.
Background technology
Existing brushless Permanent Magnet, pawl is inlaid with permanent magnets on extremely before and after being, before and after pawl extremely to go up the magnetic pole loop that magnetic pole loop and pawl between the permanent magnets extremely go up magnet exciting coil close, on the yoke, be wound with three reactance windings under the magnet exciting coil, three reactance windings are connected on respectively on the stator winding of three phase places before the rectifier.This generator leakage field is little, specific power is big, voltage regulation result good, but shortcoming has been to use electric magnet exciting coil, makes to lower efficiency complex structure, generation loss and heating.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point of the prior art and a kind of simple in structure, volume is less, specific power is high, assembling is easy, operational reliability the is high novel permanent magnetic alternating current generator that provide.The utility model is realized in the following way: the utility model is by rear end cap, magnet exciting coil, stator coil, stator, the left side pawl utmost point, the right pawl utmost point, front end housing, compositions such as rotating shaft, at the left pawl utmost point, on the medial surface of the right pawl utmost point and axis normal, be pasted with the different disk magnet ring of polarity, along the maximum cylindrical of rotor internal cavity, the sector magnet ring evenly distributes at the pawl utmost point back side, at the left pawl utmost point, between the sector magnet ring between the right pawl utmost point and accompany the good annulus iron yoke of magnetic conductivity between the disk magnet ring respectively, play the magnetic conduction effect, between pawl pole axis hole and rotating shaft, be equipped with every the magnetic axis cover, to form effective closed magnetic circuit.
The utility model has alleviated the weight of the utility model rotor greatly owing to two structures such as solid-iron yoke having cancelled electric magnet exciting coil, brush, slip ring and played axial magnetic conduction effect, and the specific power height is fuel-efficient energy-conservation; Assemble easyly, cost is low; The spark that no slip ring, carbon brush cause, dust, maintenance is little, moves more reliably, and helps environmental protection.
Description of drawings
Fig. 1 structural representation of the present utility model.
The structural representation of Fig. 2 the utility model pawl utmost point rotor.
The K of Fig. 3 the utility model pawl utmost point rotor structure is to view.
Embodiment
The utility model embodiment now is described in detail in detail in conjunction with the accompanying drawings, as Fig. 1, Fig. 2, shown in Figure 3, in the rotor internal cavity between the left pawl utmost point 4, the right pawl utmost point 5, two disk magnet rings 8 that polarity is different are attached to respectively on the medial surface of the left and right two pawl utmost points and axis normal, and disk magnet ring center is concentric with axis; Sector magnet ring 9 (totally 12) then is evenly distributed on the back side of each pawl utmost point along the maximum cylindrical of rotor internal cavity.Disk magnet ring on the left side pawl utmost point 4 is identical with sector magnet ring polarity, if be all the N utmost point, the disk magnet ring on the then right pawl utmost point 5 or the polarity of sector magnet ring should be opposite, are the S utmost point.9 of sector magnet rings between the left and right pawl utmost point accompany the good annulus iron yoke 10 of magnetic conductivity, accompany the good annulus iron yoke 12 of magnetic conductivity 8 of disk magnet rings, play the magnetic conduction effect, form effective closed magnetic circuit.What one bronze medal or alloy aluminum material were housed between pawl pole axis hole and rotating shaft 7 overlaps 11 every magnetic axis, flows to the two ends of axle to avoid the magnetic line of force, makes every effort to the leakage field minimum in the magnetic loop, guarantees the most effective utilization of magnetic flux and sends maximum power.
Claims (1)
