Abstract
The utility model discloses a compound manent-magnet generator for an automobile. In the compound manent-magnet generator for an automobile, two polar claws in a rotor are made of Nd-Fe-B material, permanent magnets are arranged between the two polar claws, and the permanent magnets are mutually connected by stainless steel rings; the arrangements of the magnet poles of the permanent magnets are corresponding to the magnetic performance of the polar claws, the permanent magnets can be replaced by a magnetic ring, the magnetic ring of a permanent magnet is sheathed between the two polar claws, and the magnetic ring is welded by stainless steel. The compound manent-magnet generator for an automobile has exciting windings, so electric excitation can be carried out; the utility model also has the function of excitation by permanent magnets, so the performance of the generator is made to be stabler, and use effect is obviously improved.
Description
The utility model relates to a kind of improvement of automobile generating machine, and this improved generator can use with automobile, the tractor of various models.
Along with science and technology constantly develops, the use field of permanent magnetic material also more and more widely, its application on electric motor of automobile has suitable DEVELOPMENT PROSPECT, therefore many relevant technical schemes appear recently, for example, Chinese patent CN2194045Y number its bottom is embedded with strip permanent magnet about propose a kind of non-magnetic conduction connector of mouse cage shape that affixed magnetic conductive core is all arranged in " p-m rotor " between magnetic conductive core, the center is by the non-magnetic conductive core location of tape spool, and the end compresses with non-magnetic conductive board.Owing to this p-m rotor problem structurally, influenced the output performance of motor.
Task of the present utility model is the permanent magnetic generator for vehicle that a kind of combined type will be provided, it can keep the characteristic of automotive brushless generator, possesses the advantage of permanent magnet generator again, and plays the effect of mutual compensation on two kinds of structures, make the performance of this generator more perfect, result of use is better.
Task of the present utility model is finished in such a way, this composite automobile permanent magnet generator and original automotive brushless generator are similar substantially, but the pattern that adopts brazing or stainless steel to be welded to connect at two utmost point pawls of rotor is transformed to Nd-Fe-B magnet steel and sets and connect with stainless steel ring, and it is corresponding with the magnetic of two utmost point pawls that the magnetic of this permanent magnet distributes.In addition, two utmost point pawls of this of rotor also can adopt the magnet ring of permanent magnet to be connected with stainless steel, and the distribution of the polarity of magnet ring also should be corresponding with the magnetic of two utmost point pawls certainly.No matter can both normally work when this composite automobile permanent magnet generator is low speed or high speed, having overcome magneto magnetic force when hot effectively descends and the output current out-of-control phenomenon, guarantee that motor has stable power output to satisfy the needs of various automobiles, energy-saving effect is obvious.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Fig. 1 is an automobile generator rotor structure chart of the present utility model.
Fig. 2 is a pole jaw of car electricity generator cutaway view of the present utility model.
As can be seen from Figure 1, this composite automobile rotor of permanent-magnetic power generator (1) structure is identical with automotive brushless generator substantially, in rotor (1) inside inner-stator iron core is housed still, but not to adopt brazing or stainless steel to connect between utmost point pawl (2) and (3), but be embedded in the middle of them by the permanent magnet (4) that NdFeB material is made, and with a stainless steel ring they are linked together, the pole arrangement of each permanent magnet (4) is corresponding with the magnetic pole of utmost point pawl (2) and (3).Fig. 2 then is the cutaway view of this composite automobile rotor of permanent-magnetic power generator (1), permanent magnet (4) substitutes with the magnet ring (5) of permanent magnet, be the magnet ring (5) of applying mechanically a permanent magnet like this between the utmost point pawl (2) of rotor and (3), utmost point pawl (2) and (3) weld together with stainless steel, and the magnetic pole of this magnet ring (5) distributes also corresponding with the magnetic of utmost point pawl (2) and (3).This shows that this composite automobile permanent magnet generator had both had field winding, and to carry out electricity excitatory, possesses again the permanent magnet excitation function is arranged, and compensates effect mutually, generator is in operation remains stable power generation performance.
Claims (2)
1, a kind of composite automobile permanent magnet generator of being formed by rotor (1), utmost point pawl (2) and (3), it is characterized in that: set the permanent magnet (4) that NdFeB material is made between utmost point pawl (2) and (3), and interconnective by stainless steel ring, the pole arrangement of these permanent magnets (4) is corresponding with the magnetic of utmost point pawl (2), (3).
2, by the described composite automobile permanent magnet generator of claim 1, it is characterized in that: these permanent magnets (4) the also magnet ring of available permanent magnet (5) substitute, the magnet ring (5) of a permanent magnet of cover between utmost point pawl (2) and (3), and with stainless steel welding, it is corresponding with the magnetic of utmost point pawl (2), (3) that the magnetic pole of this magnet ring (5) distributes.
