Abstract
An armature assembly for an electric power steering brushless motor is formed by connecting 12 armature assembly units in parallel and forms an integral row-connection structure. Each armature assembly unit (2) is composed of an armature iron core (3), a nylon layer (4) and an enameled wire (5), the nylon layer (4) is wrapped on the surface of the armature iron core (3), and the enameled wire (5) is wound on the nylon layer (4). The armature assembly for the electric power steering brushless motor is excellent in insulating performance, convenient to wind and capable of avoiding a short circuit. In addition, an auxiliary groove is further inserted in the armature iron core to offset magnetic response torque of the motor, and torque fluctuations caused by the magnetic response torque are reduced.
Description
Technical field
The utility model relates to a kind of electric power steering brushless electric machine rotor assembly.Belong to the automobile electric power-assisted steering brushless electric machine and make the field.
Background technology
The armature core of the automobile electric power-assisted steering brushless electric machine rotor assembly of domestic production at present is integral type around structure, this structure difficulty that not only winds the line, and insulating properties is very poor can't the injection moulding insulating barrier, can only wrap in the surface with insulating paper, breakage causes short circuit easily in the coiling process.Simultaneously since traditional integral type around armature core can't adjust armature notch size, can't reduce the torque ripple that causes by slot effect.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of good insulation preformance, coiling conveniently, and can avoid the electric power steering brushless electric machine rotor assembly of short circuit.
The technical scheme that realizes above-mentioned purpose is: a kind of electric power steering brushless electric machine rotor assembly, it is linked together side by side by 12 rotor assembly unit and constitutes, and formation integral type platoon structure, each rotor assembly unit is made up of armature core, nylon and enamelled wire, nylon is plastic on the armature core surface, and enamelled wire is on nylon.
The armature core two ends are respectively equipped with insulation barrier.
One end of armature core has been moulded holddown groove.
After adopting technique scheme, the utility model has been compared following advantage with the rotor assembly of traditional circulating type structure: aspect coiling, rotor assembly of the present utility model can be earlier winds the enamelled wire of rotor assembly one by one and is rolled into circle then and is pressed into casing at last, and integral type is around the rotor assembly coiling of structure difficulty relatively just; Aspect insulation, the rotor assembly of integral type platoon mechanism can plastic nylon, and insulation effect is good, and integral type can only adopt insulating paper to wrap in the surface around the rotor assembly of structure, and fail safe is not high; Reducing aspect the torque ripple, the rotor assembly of integral type platoon structure can be regulated armature notch size and reduce torque ripple.
Description of drawings
Fig. 1 the utility model is installed to the structural representation in the casing;
The structural representation that Fig. 2 armature core of the present utility model links together side by side;
Fig. 3 is the structural representation behind the plastic nylon of the armature core among Fig. 2;
Fig. 4 is structural representation of the present utility model (behind a last enamelled wire).
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Shown in Fig. 2,3,4, a kind of electric power steering brushless electric machine rotor assembly, link together side by side by 12 rotor assembly unit and to constitute, and formation integral type platoon structure, each rotor assembly unit 2 is made up of armature core 3, nylon 4 and enamelled wire 5, nylon 4 is plastic on armature core 3 surfaces, and enamelled wire 5 is on nylon 4.
One end of armature core 3 has been moulded holddown groove 7.Holddown groove 7 can be used for fixing enamelled wire 5 and patch bay.
As shown in Figure 1, electric power steering brushless electric machine of the present utility model is pressed into casing 1 after utilizing equipment to be rolled into circle with rotor assembly.
Also insert auxiliary ditch 8 in the armature core 3 and offset the magnetic response moment of motor, reduced the torque ripple that magnetic response moment is brought.
The utility model has guaranteed the consistency of armature thickness, makes motor properties more stable.
