Abstract
The utility model relates to a permanent magnet brushless direct current (DC) motor rotor, which comprises a rotor core or a shell and a magnetic steel adhered to the rotor core or the shell and is characterized in that the magnetic steel is integrally molded with the rotor core or the shell into one whole body. In the permanent magnet brushless DC motor rotor of the utility model, after the original magnetic steel is adhered to the rotor core or the shell, an injection molding process is increased so that the rotor core or the shell and the adhered magnetic steel are integrated into one whole body by injection molding technology. The processing quality of the rotor is effectively improved by the double fixation of adhesion and injection molding.
Description
Technical field
The utility model relates to the technical field of permanent-magnet brushless DC electric machine, specifically is a kind of permanent-magnet brushless DC electric machine rotor of high reliability.
Background technology
The rotor of present permanent-magnet brushless DC electric machine be stick with glue agent with bonding magnetic steel on rotor core or housing/housing, its bonding quality can't accurately detect, and existing detection means all has destructiveness to a certain degree, so behind the product export, the phenomenon that still has the minority magnet steel to come off.
How improving the reliability of permanent-magnet brushless DC electric machine rotor, and solve the uncertainty of bonding magnetic steel quality, is the technical barrier of this area.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of simple in structure, permanent-magnet brushless DC electric machine rotor that reliability is higher.
For solving the problems of the technologies described above, the permanent-magnet brushless DC electric machine rotor that the utility model provides comprises: as rotor core or the housing and the magnet steel that is adhered on rotor core or the housing of rotor, be characterized in: magnet steel and rotor core or housing are injection molded into one.
The technique effect that the utlity model has: permanent-magnet brushless DC electric machine rotor of the present utility model, after original bonding magnetic steel is on rotor core or the housing, increase the injection mo(u)lding operation one, make rotor core or housing (being magnetic conductor), bonding magnet steel constitute an integral body by injection molding technology.Through the gluing crudy that has improved rotor with the method for injection moulding double fixed effectively that connects.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structural representation of the permanent-magnet brushless DC electric machine rotor among the embodiment.
Fig. 2 is the decomposition chart of described permanent-magnet brushless DC electric machine rotor.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1-2, the permanent-magnet brushless DC electric machine rotor of present embodiment comprises: as rotor core or the housing 1 and the magnet steel 2 that is adhered on rotor core or the housing 1 of rotor, magnet steel 2 is injection molded into one with rotor core or housing 1.
Form the injection moulding support 3 among Fig. 2 behind the injecting plastic forming.
Present embodiment be on magnet steel 2 has bonded to as the rotor core of rotor or housing 2 after, strengthen the adhesive strength of magnet steel by injection mo(u)lding.
The quantity of magnet steel 2 is the designing requirement decisions according to product, and for the internal rotor permanent-magnetic brushless electric machine, magnet steel 2 is to be bonded on the rotor core, and for the external rotor permanent magnet brushless electric machine, magnet steel 2 is bonded on the housing.By injection moulding, on the one hand can be to reinforcing once more between the two, it is as a whole that injection mo(u)lding can make several magnet steel moulding of product on the other hand, can remedy the bonding defect of indivedual magnet steel.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection range of the present utility model.
