Abstract
The invention relates to a permanent magnetic pole rotor between claw poles. A strip bulge of a front claw pole is in positioning connection with a strip positioning groove of a rear claw pole; claw magnetic poles are alternate; a magnet fixing piece is arranged in a gap between the claw magnetic poles of the front claw pole and the rear claw pole and provided with two magnet accommodating parts in a eudipleural mode; a permanent magnet is arranged in each magnet accommodating part; a first connector is connected with the two magnet accommodating parts which are arranged in the eudipleural mode; a second connector is connected with the first connector; and the strip groove and a strip magnet fixing piece positioning groove of the claw poles are fixedly connected through the second connector. The invention has the advantages that: the magnet fixing piece is arranged in the gap between the claw magnetic poles of the front claw pole and the rear claw pole, so that the rotor is convenient to install and implement, the performance of a generator is obviously improved, an obvious energy-saving effect is achieved, the current of the rotor is 5 to 10A higher than that of a similar product, higher utilization efficiency and fuel oil economy are achieved, and noise generated by magnetic leakage is reduced.
Description
Technical field
The present invention is a kind of pawl interpolar permanent magnetism magnetic pole rotor of motorcar alternator.
Background technology
The vehicle alternator service efficiency often is restricted, fuel economy also can be restricted, the noise that electromagnetism brings is bigger, operating efficiency when the vehicle alternator field of the survival of the fittest increases generator low speed becomes extremely important, increases the operating efficiency of alternator for vehicle when vulgar based on above requirement and becomes particularly important.
Between common rotor claw utmost point magnetic pole very big interval is arranged, in the time of generator work, owing to middle interval causes leakage field bigger, if two pawl interpolars are filled up midfeather with permanent magnets under this structure, if permanent magnet can not be fixed, must in the high speed rotating of rotor, come off, influence the safe handling of vehicle alternator.
Summary of the invention
The objective of the invention is to, a kind of pawl interpolar permanent magnetism magnetic pole rotor that solves permanent magnet placement and fixation problem is provided.
The present invention is achieved in that the inboard, middle part of the fore paw utmost point is provided with raised strip, and the outside of the fore paw utmost point is provided with banded magnet fixture detent, the claw-like magnetic pole sidepiece detent of the fore paw utmost point, and the edge of the claw-like magnetic pole of the fore paw utmost point is provided with the positioning body.
The inboard, middle part of the rear solid end utmost point is provided with banded detent, the claw-like magnetic pole sidepiece detent of the rear solid end utmost point, and the edge of rear solid end utmost point claw-like magnetic pole is provided with the positioning body.
The extremely banded detent of the raised strip of the fore paw utmost point and rear solid end is located by connecting, the claw-like magnetic pole alternately, the magnet fixture is installed at the claw-like magnetic pole of the fore paw utmost point and place, the claw-like pole piece spacing of the rear solid end utmost point, said magnet fixture two the magnet accommodation sections that have been symmetrically arranged, magnet is placed permanent magnet in the accommodation section, first connector connects two magnet accommodation sections that are symmetrically arranged, and second connector connects first connector; Be connected and fixed by second connector and the banded magnet fixture of the extremely banded groove of pawl detent.
Advantage of the present invention is, the magnet fixture is installed at the place, claw-like pole piece spacing of the fore paw utmost point, the rear solid end utmost point, be convenient to install and implement, the magnet fixture has limited the permanent magnet motion that radius vector makes progress when rotor high-speed rotates, only need machinery to install, do not need welding and other location measure, solve the permanent magnet fixation problem easily, performance to generator has more significantly lifting, also there is obvious effects the energy savings aspect, exceeds the electric current of 5～10A than like product performance, has obtained higher service efficiency, better fuel economy has reduced the noise that leakage field produces.
