Description

A kind of concatenation type DC generator
Technical field
This utility model is related to a kind of electromotor, more particularly to a kind of concatenation type DC generator.
Background technology
Electromotor is the equipment that mechanical energy is transformed into into electric energy.Generally driven by steam turbine, the hydraulic turbine or internal combustion engine, electric energy It is one of topmost energy of contemporary society.Electromotor has extensive use in industrial and agricultural production, national defence, science and technology and daily life On the way.And current existing electromotor, it is big all to there is starting reactance in no matter high-rating generator, or small generator, it is difficult to start Problem, and existing DC generator generated energy is little, and generating efficiency is low.
The content of the invention
It is little that technical problem to be solved in the utility model is to provide a kind of starting reactance, can increase generated energy, improves and sends out The concatenation type DC generator of electrical efficiency.
To solve the above problems, this utility model is adopted the following technical scheme that:
A kind of concatenation type DC generator, including stator and rotor, the stator includes stator case, stator core and determines Sub- winding, it is characterized in that:The stator is multiple and is sequentially connected in series that each stator is drawn respectively in its stator case one end Two terminals, for the electric current that output is produced;End cap is respectively arranged at two ends with multiple stators, the circumference between two end caps Stock is uniformly connected with, is fixed for the concatenation between multiple stators;The rotor include armature spindle and be located on armature spindle and , in the permanent magnets of installation set outer rim, armature spindle pacified by bearing for the corresponding multiple installation sets of each stator core and circumference uniform distribution It is mounted between two end caps;The central angle for being used to wind corresponding to the boss of stator winding on the stator core is α, Duo Geding The quantity of son is n, and the stator core of two neighboring stator differs successively clockwise or counterclockwise α/n degree in multiple stators.
As further preferred, the seam and phase interfix for cooperating is provided between the stator case of adjacent two stators Connect, for ensureing the connection of multiple stators after axiality.
Used as further preferred, wheel for inputting is drawn by a side end cap and be provided with to the armature spindle, for connecting power source Drive rotor rotation.
Used as further preferred, the stator is four.
Used as further preferred, installation set outer rim is inlayed and be bonded in the permanent magnets, sets between adjacent two permanent magnets There is fluid sealant.
The beneficial effects of the utility model are:Because the stator is multiple and is sequentially connected in series, adjacent two in multiple stators The stator core of individual stator differs clockwise or counterclockwise successively α/n degree, therefore the rotor of the concatenation type DC generator can be Stator core inner periphery optional position stops, and starting reactance is little, and generated energy can be made to be multiplied, so as to greatly improve the effect that generates electricity Rate.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is to remove the left view after the end cap of left side in Fig. 1.
Fig. 3 is the partial enlarged drawing of Fig. 1.
In figure:Stator case 1, stator core 2, boss 201, stator winding 3, terminals 301, permanent magnets 4, armature spindle 5, Installation set 6, wheel for inputting 7, end cap 8, arc convex 801, stator 9, stock 10.
Specific embodiment
As shown in FIG. 1 to 3, a kind of concatenation type DC generator that this utility model is related to, including stator 9 and rotor, The stator includes stator case 1, stator core 2 and stator winding 3, if stator core 2 is to be added to form by dry tablet silicon steel sheet stack And be fixed in stator case 1, stator winding 3 is respectively wound around and is distributed on the boss 201 of the inner edge of stator core 2.
The stator 9 is multiple and is sequentially connected in series that the present embodiment is by taking four stators as an example.The stator winding 3 of each stator Respectively two terminals 301 are drawn in its one end of stator case 1, for the electric current that output is produced.It is multiple what is linked together The two ends of stator are plugged with respectively end cap 8, and circumference uniform distribution is connected with stock 10 between two end caps 8, for multiple stators it Between concatenation fix.Arc convex 801 is evenly equipped with the outer marginal circumference of end cap 8, the two ends of the stock 10 are convex by corresponding arc Play through and pass through nut check.The seam that cooperates is provided between the stator case 1 of adjacent two stators and is mutually inserted, For ensure multiple stators be connected with each other after axiality.
The rotor include armature spindle 5 and be located on armature spindle 5 multiple installation sets 6 corresponding with each stator core 2 with And circumference uniform distribution, in the permanent magnets 4 of the outer rim of installation set 6, armature spindle 5 is arranged on two end caps 8 through multiple stators and by bearing Between;The central angle for being used to wind corresponding to the boss of stator winding 3 on the stator core 2 is α, and the quantity of multiple stators is N, the stator core 2 of two neighboring stator differs successively clockwise or counterclockwise α/n degree in multiple stators.
Wheel for inputting 7 is drawn by a side end cap 8 and be provided with to the armature spindle 5, for connecting the rotation of power source drive rotor. The outer rim of installation set 6 is inlayed and be bonded in the permanent magnets 4, and between adjacent two permanent magnets 4 fluid sealant is provided with.
When using, two terminals 301 that the stator winding 3 of each stator is drawn are connected respectively by commutator with storage battery Connect.By the power source drive rotor rotation in the stator core 2 for connecting wheel for inputting 7, because the stator is four and successively Concatenation, the stator core 2 of two neighboring stator differs clockwise or counterclockwise successively α/n degree, therefore the concatenation in four stators The rotor of formula DC generator can stop in the inner periphery optional position of stator core 2, and starting reactance is little, the stator of each stator around The electric current that group 3 is produced enters respectively storage battery after rectifier rectification.
