Abstract

The utility model relates to a novel generator, more specifically a coreless generator adopting a novel coil winding mode as well as a novel position for placing magnets, which mainly comprises a rotor shaft, a magnet, a support bracket, a bearing, enameled wires, a housing, gear wheels and a driving device. The utility model has the advantage of simple structure and changes the conventional arrangement. Because no core is provided, the reluctance force is reduced, and the efficiency of power generation is increased. The utility model opens a new generation of generators.

Description

Generator

The utility model relates to a kind of new type electric generator, relate to or rather a kind of with novelty the coil windings mode and with the magnet placement location of novelty, and do not have the generator of iron core.

Present generator generally all is made up of winding iron core and magnetic field, when generator starting, its magnetic field and winding iron core produce certain reluctance force (being resistance or title suction), when generator produces electric current, iron core has produced magnetic field, form excitatory, the resistance limits rotor occurs and freely turn round, so restriction occurs, generator is in running in addition, motor itself produces very big heat, this is owing to produce eddy current on stator, and because the effect of electric current, makes to produce heat on iron core and the coil, this heat impels the resistance in the winding coil to increase, and has reduced energy output.

The purpose of this utility model is exactly the shortcoming that overcomes the generation current machine, and a kind of new type electric generator is provided, and it has changed present generator Structure, make that the resistance in the generator reduces to minimum value, thereby the efficient of generator is able to very big raising.

The purpose of this utility model realizes that by following content generator of the present utility model comprises armature spindle, magnet, support, bearing, enamelled wire, shell and gear and drive unit; Wherein armature spindle passes magnet and is combined into magnet, the utmost point of magnet is to vertical with armature spindle, there is the support that is used for twining enamelled wire the outside of magnet, combine by bearing between support and the armature spindle, between the inwall of support and the outer surface of magnet certain distance is arranged, twine enamelled wire on the support, forming coil; Make that so just the coil on the support is a stator, armature spindle and magnet are rotor.Described magnet is made of cylinder, this cylinder is made up of two semicircular body, a cylindrical semicircle of forming is the N utmost point, another semicircle is the S utmost point, or form cylinder to alternate magnet by some N, the S utmost point, and described support is that a housing with the magnet appearance similar constitutes, promptly the semicolumn housing of two symmetries is formed, convenient for winding around, two plate washers can be set in the housing outer end; It is to twine like this that enamelled wire is wound on the support, enamelled wire is wound in respectively on the semicolumn housing of symmetry on two, at last the overhang on two symmetrical semicolumn housings is joined with the form of series connection, and promptly the line end on both sides is end to end, final two terminations that form are as output.Can combine by binding agent or connector between two symmetrical semicolumn housings of formation support, support is fixed by connector and housing, one end of armature spindle is equipped with a gear, and drive unit flows to gear with power, promptly drives the armature spindle that magnet is housed and rotates.After exterior power rotated by the gear driven armature spindle, the magnet on the armature spindle also rotated thereupon, make it as stator with frame on coil on induce the magnetic field of variation, the output at coil produces electric current like this.Because this motor does not have iron core, does not have eddy current between stator and the rotor, seldom produce heat.Because when the magnet zero load is rotated, make its on coil, induce with the magnet pole of process to identical magnetic field, the magnetic field that coil induced produces repulsion with the magnet that is just being passed through like this, thereby do not have in the original generator owing to the excitatory resistance that produces between stator and the rotor that makes, so its stroke becomes the sliding power of inertia magnetic, thereby has improved generating efficiency greatly.

The utility model is simple in structure, and it has changed traditional arrangement mode, owing to do not have iron core, thus reduced reluctance force, improved generating efficiency, it is the rotor machine of a new generation.

Below in conjunction with accompanying drawing, further describe structure of the present utility model, wherein:

Fig. 1 is the structural representation of an embodiment of the utility model generator;

Fig. 2 is the generalized section of Fig. 1;

Now referring to attached Fig. 1 and 2,1a among the figure, 1b are astragal, and 2 is armature spindle, and 3a, 3b are support, and 4 is gear, and 5 is bearing, and 6 is magnet, and C, D are output.Armature spindle 2 passes magnet 6 and is combined into magnet 6, and the utmost point of magnet 6 is vertical with armature spindle 2 to N, S; Support is the semicircle housing 3a by two symmetries, 3b constitutes, and two plate washer 7a and 7b are arranged, length direction is parallel with armature spindle 2, and magnet 6 is positioned over the housing 3a of support, in the 3b, the outside of magnet 6 and support 3a, certain distance is arranged between the inwall of 3b, and this distance is 0.1-0.5mm, the semicolumn housing 3a of two symmetries of support that combine, on the 3b, following two ends combine with armature spindle 2 by bearing 5, at the semicolumn housing 3a of two symmetries of support, the outside of 3b is wound with coil 1a, 1b, enamelled wire is wound in two symmetrical semicolumn housing 3a respectively to be parallel to armature spindle (K to), 3b forms coil 1a, 1b, at last with two symmetrical semicolumn housing 3a, coil 1a on the 3b, two termination C of both positive and negative polarity are drawn with headtotail in the end of 1b, D.Support 3a, 3b fixes (not shown) by connector and housing, and an end of armature spindle 2 is equipped with a gear 4, and drive unit (not shown) flows to gear 4 with power, promptly drives the armature spindle 2 that magnet 6 is housed and rotates.

Generally speaking, the material of armature spindle is to be made of the metal material of not inhaled by magnet, as copper or stainless steel etc.), the material of support is plastics, and the used line of coil is a fine copper wire, and housing requires non-magnet material to constitute.It should be noted that when winding around, should note not being contacted with armature spindle, with anti-wear.The employed fineness degree of coil that twines, and the intensity of magnet can be selected according to needed generated output.

Example:

Select 2500 Gausses (the about 18mm of cylinder diameter for use as the magnet of rotor, high 28mm), the enamelled wire straight line is selected 0.65mm for use, on support, twine 640 circles altogether, and draw two ends, when the speed rotation that external impetus changes with per minute 3000 by armature spindle, then the electric power of output (C, D place) generation at stator is 40W.
