Abstract

The utility model relates to a low reluctance magneto alternator, which is composed of two stators and a rotor; wherein the two stators are arranged in an upper and a lower shell respectively; the rotor is arranged in a rotor shaft. The utility model is characterized in that: a stator module is composed of an iron core and coils and is fixed on the shells in sequence; each stator coil is connected together in parallel or in series. As the coils and the iron core is modularized, magnetic field loss can be reduced when the alternator is in operation and electricity generating efficiency is improved by improving processing accuracy and quality of the coil winding. The utility model is easy to form large scale production, thereby simplifying the producing techniques and reducing manufacturing cost.

Description

A kind of disc type is hanged down the magnetic resistance magneto alternator

(1) technical field

The utility model relates to desk permanent-magnet alternating current generator field, and specifically a kind of disc type is hanged down the magnetic resistance magneto alternator.

(2) background technology

Though it is simple in structure that existing desk permanent-magnet alternating current generator has, volume is little, and is in light weight, advantage of low manufacturing cost.But in the installation process of the manufacturing of stator winding and permanent magnet; because the error of making causes the inhomogeneous of Distribution of Magnetic Field easily; increased magnetic resistance; often solve this problem by improving measures such as performance accuracy and crudy; so not only improve processing cost, also be unfavorable for large-scale production.

(3) summary of the invention

The utility model is exactly in order to overcome above-mentioned shortcoming, propose a kind of loss of field little, be convenient to produce in enormous quantities, the low magnetic resistance magneto alternator of disc type of low cost of manufacture.

Goal of the invention of the present utility model is realized by following technical scheme: a kind of disc type is hanged down the magnetic resistance magneto alternator, comprise the stator that is installed in upper shell 1, the lower house 2, be installed in the rotor 5 on the armature spindle 6, it is characterized in that the stator modules that iron core 8 and coil 4 are formed is that sequence arrangement is fixed on the housing, each is organized stator coil 4 parallel connections or is cascaded.The surface area of iron core 8 can be identical with the corresponding surface area that is fixed on the permanent magnet 3 on the rotor 5, also can be inequality.

The iron core 8 of stator modules has groove, and coil 4 embeds in the groove.The shape of each stator modules is identical with size, and can peg graft continuously or splice, and iron core 8 is press-fited by silicon steel sheet to be combined.

The outer rim of disk type rotor 5 is equipped with permanent magnet 3, circularizes even distribution.

Stator modules is packed on the housing, and is corresponding one by one with permanent magnet 3 on the rotor 5.

Stator modules is contained in the axial one or both sides of rotor 5.

Iron core 8 is eccentric circular ring shapes, and the assembly that iron core is 8 is inserted face and is the plane or is concavo-convex tongue and groove shape.Stator modules after can making assembly slotting ringwise.

The utility model is with coil and iron core modularization, can improve the machining accuracy and the quality of stator winding, reaches to reduce magnetic field loss in the generator course of work, improves the purpose of generating efficiency; Be easy to form large-scale production, simplified production technology, reduced manufacturing cost.

(5) embodiment

Fig. 1 is a kind of embodiment of the present utility model, and it is the low magnetic resistance magneto alternator of a kind of single stator disc type.Upper shell 1 and lower house 2 are fixed together, and rotor and stator are installed in the space of upper shell 1 and lower house 2.Armature spindle 6 is installed in the brearing bore on upper shell 1 and the lower house 2, passes from the center of housing 1, and rotor 5 is connected with armature spindle 6 usefulness keys, and permanent magnet 3 is installed in the outer rim of disk type rotor 5, and permanent magnet 3 shown in Figure 3 circularizes even distribution.Stator modules is packed on the lower house 2, and Fig. 2 and stator modules shown in Figure 3 are corresponding one by one with permanent magnet 3 on the rotor 5.Fig. 4 and Fig. 5 are the structural representations of stator modules among Fig. 1, and the iron core 8 of stator modules has groove, and coil 4 embeds in the groove, and the shape of each stator modules shown in Fig. 2 is identical with size, and shown in Figure 6 is the splicing schematic diagram of the stator modules of Fig. 4 and Fig. 5.Coil 4 shown in Figure 2 is to be connected in series, and the head end 10 of first coil 4 and the end 10 of last coil are drawn casing.Coil 4 also can be to be connected in parallel.

Fig. 7 is the low magnetic resistance magneto alternator of a kind of pair of stator disc type, and the difference of it and Fig. 1 is that the outer rim of disk type rotor 5 is that 3, two groups of stator modules of permanent magnet are packed in respectively on the upper shell 1 upper and lower housing 2, and is corresponding one by one with permanent magnet 3 on the rotor 5.The low magnetic resistance magneto alternator of two stator disc types of Fig. 7 is than the low rare increase of magnetic resistance magneto alternator volume of single stator disc type of Fig. 1, but energy output is greatly improved, and cost rises little, but benefit is greatly improved.

Fig. 8 is the plugboard chart of the stator modules of another kind of embodiment, and it only is that with the difference of Fig. 6 the assembly of stator modules inserts the different of part.

Coil and iron core that modularization is produced have been simplified production technology, have reduced manufacturing cost, have improved machining accuracy and quality, make Distribution of Magnetic Field even, have reduced the magnetic field loss, have improved generating efficiency.
