Description

Distributed winding formula permanent magnetism fly-wheel generator

The utility model relates to the permanent magnetism fly-wheel generator that a kind of small diesel engine is used.

The permanent magnetism fly-wheel generator that existing small diesel engine adopts is to concentrate the winding type permanent magnetism fly-wheel generator, is generally three winding type generators.Be loaded on single cylinder diesel flywheel inboard, be used for illumination or charge in batteries.As shown in Figure 1, it concentrates winding 2 by stator core 1, and p-m rotor 3 is formed.When the p-m rotor 3 on being contained in flywheel rotated, magnetic force line cutting was loaded on the concentrated winding in three stator cores on the body, produces alternating voltage.Because it all adopts the winding mode of concentrating, the interior Chinese People's Anti-Japanese Military and Political College, efficient is low, thereby power is less than normal, be difficult to satisfy the electricity consumption requirement that electricity such as agricultural tricycle, tractor with small four wheels start, the user presses for a kind of high-power permanent magnet, fly wheel generator that does not change original installation dimension and volume.

The purpose of this utility model provides a kind of distributed winding and high permanent magnetism fly-wheel generator of power output of adopting.

The purpose of this utility model realizes by following technical solution:

Permanent magnetism fly-wheel generator described in the utility model is made up of housing, stator core, distributed winding, p-m rotor, the stator core of housing internal fixation, and be fixed on the body, be characterized in that this stator core is an integral type, the garden offers the line embedding groove of equal distribution altogether on week, and distributed winding divides three groups evenly to distribute and be wound in the line embedding groove in the stator core, and p-m rotor is positioned at stator core, it is made of permanent magnet some, and is fixed on the flywheel.

The utility model has the advantages that: it is compared with concentrating the winding type permanent magnetism fly-wheel generator at present, owing to adopt the distributed winding structure, the voltage that its three phase winding is produced, electric current output electrical degree be evenly distributed (being that the phase angle is evenly distributed), its voltage, electric current are output as sine wave, waveform is good, and it is little to fluctuate, and distortion is few, the efficient height improves the fail safe of power consumption equipment.And voltage, the current waveform of concentrating its output of winding type permanent magnetism fly-wheel generator are the peaked wave of deformity, the electrical degree skewness, and efficient is low, and fluctuation is big, thereby big to the influence of power consumption equipment, makes that the fail safe of power consumption equipment is relatively poor.Secondly, it adopts the distributed winding structure, and the internal impedance of its winding is little, thereby output current is big, and concentrates the impedance of winding construction winding big, and output current is less, electric current output greatly.In addition, improvement of the present utility model does not relate to the change of original fly wheel generator overall dimensions, just the change of internal structure.Therefore, under the situation that does not change original fly wheel generator external form, size, still can be installed on single cylinder diesel flywheel inboard, and power output is improved.As be equipped with suitable adjuster, and can be used for the three wheeled transport vehicle used for farm of electric actuated type or non-electric actuated type, on the tractor with small four wheels, can satisfy the needs of each electrical appliance to charge in batteries.

Below in conjunction with an embodiment, the technical solution of the utility model is described further:

What Fig. 1 provided is the existing structural representation of concentrating the winding type fly wheel generator:

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is that the axle of Fig. 2 cuts open schematic diagram;

Fig. 4 is that the coiling of distributed winding launches schematic diagram.

In Fig. 2, the 1st, stator core, be fixed in the housing 4, and be fixed on the body by housing 4, this stator core 1 is the integral type tubular construction, has the line embedding groove (referring to the line embedding groove among Fig. 3 6) of several equal distribution in it on the side face of garden, distributed winding 2 is divided into three groups, constitute three phase windings, evenly distribution is wound on the line embedding groove 6 interior (referring to Fig. 2) in the stator core 1, and the number of line embedding groove and the number of turns of distributed winding determine the size of its power output.P-m rotor 3 is positioned at stator core, and it is made of permanent magnet some, and is fixed on the flywheel by flywheel shaft 5.The axle that Fig. 3 has provided its structure cuts open figure, and 1 among the figure is stator core, and the

line embedding groove

6,2 that has some equal distribution on it is for being embedded in the distributed winding in this line embedding groove, and 3 is p-m rotor, is contained on the flywheel shaft 5 and by flywheel shaft 5 to be fixed on the flywheel.The 4th, housing.Fig. 4 has provided the coiling schematic diagram of distributed winding, and 1 is the stator core that launches among the figure, and the 6th, the line embedding groove of offering on the side face of garden in this stator core, distributed winding 2 is divided into 2-1,2-2, three equally distributed windings of 2-3, is wound in the line embedding groove 6.Operation principle of the present utility model is as follows: when starting diesel engine, its flywheel rotation drives p-m rotor 3 and rotates in stator core, produce relative motion between rotor and the distributed winding and make, the magnetic field of permanent magnet of p-m rotor is distributed the winding cutting, thereby generation induced potential, form alternating voltage, connect load and promptly form alternating current.The size of its power output is put to death the number in line embedding groove, the number of turn of distributed winding and the magnetic field intensity of p-m rotor permanent magnet, suitably chooses its parameter, can obtain corresponding output power.
