Abstract

The utility model discloses a generator with coil constant speed cutting constant magnetic field magnetic line, which is composed of a pedestal, a casing, a bearing seat, a belt pulley, a rotating shaft, a carbon brush, an annular SN magnetic pole, and a cutting magnetic coil rotating wheel, wherein, the cutting magnetic coil rotating wheel is arranged between an S pole and an N pole of the annular SN magnetic poles; an inner conductive loop of the cutting magnetic coil rotating wheel is fixed on a rotating shaft; the carbon brush is respectively contacted with the rotating shaft and the conductive ring on the outside. The angle for cutting magnetic line of the utility model is maintained in the best angle as 90 DEG and is not changed so as to exert the efficiency of the generator fully. Stable and constant direct current voltage and electric current can be output with safe usage.

Description

Winding constant speed cutting and constant magnetic field flux elctric generator

The utility model relates to a kind of DC generator.

At present, DC generator of the prior art generally all adopts commutator or rectifying device that the voltage and current that generator sent is transformed into direct current output, because the direction of the coil of generator its coil cutting when cutting magnetic line and the angle of the magnetic line of force are in continuous variation, this has not only reduced the efficient of generator, and the induced potential that makes on the generator coil to be produced or electric current also are constantly to change in certain scope, even the voltage of this continuous variation or electric current are handled through commutator on the DC generator or rectifying device, the voltage of its output or current waveform also are to fluctuate in certain scope, therefore for some higher power consumption equipment of stability of waveform that requires direct voltage or electric current, DC generator of the prior art still can not meet the demands.

The purpose of this utility model is: the more constant rotor machine of voltage and current dc waveform that a kind of generating efficiency is higher, simple in structure, export is provided.

The utility model is to constitute like this: it is by base (1), shell (2), bearing pedestal (3), belt pulley (4), rotating shaft (5), carbon brush (6) and (7), and annular SN magnetic pole (8) and cutting magnetic line circle runner composition, annular SN magnetic pole (8) is contained in the shell (2), bearing pedestal (3) is contained on the shell (1), belt pulley (4) is contained in the rotating shaft (5), rotating shaft (5) is contained on the bearing pedestal (3), shell (2) is fixed on the base (1), cutting magnetic line circle runner is contained between the S utmost point and the N utmost point of annular SN magnetic pole (8), cutting magnetic line circle runner is by outer conducting ring (9), interior conducting ring (10), connecting rod (11), straight lead (12) is formed, connecting rod (11) is fixed together outer conducting ring (9) and interior conducting ring (10), be connected with straight lead (12) between conducting ring (9) and the interior conducting ring (10) outside, interior conducting ring (10) is fixed in the rotating shaft (5), carbon brush (6) and (7) are contained on the shell (2), wherein carbon brush (6) contacts with rotating shaft (5), and carbon brush (7) contacts with outer conducting ring (9).

Owing to adopted technique scheme, compared with prior art, the coil of the utility model cutting magnetic line is straight lead (12), the cutting angle of itself and magnetic field magnetic line remains at best angle and goes up constant for 90 °, and any point is constant owing to its cutting angle when cutting magnetic line on the coil, so the speed of its cutting is constant all the time, has so not only given full play to the efficient of generator, but also steady constant VD and electric current have been obtained; The utility model has been owing to cancelled commutator and rectifying device in addition, so structure is very simple, and in use, owing to there is not commutator, the utility model can not produce spark, uses more safe and reliable.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is that the A of accompanying drawing 1 is to diagrammatic sketch.

Embodiment of the present utility model: base (1), shell (2) adopts steel, iron, metal materials such as aluminium are made, the bearing of bearing pedestal (3) adopts plain ball bearing, its pedestal partly adopts insulating material to make, outer conducting ring (9) with cutting magnetic line circle runner, interior conducting ring (10), connecting rod (11) is made of brass material, during making connecting rod (11) and outer conducting ring (9) and interior conducting ring (10) linked together and carry out integral manufacturing, straight lead (12) can adopt common enamelled wire finished product, power output size according to motor, connect between conducting ring (9) and the interior conducting ring (10) outside and go up tens of extremely thousands of straight leads (12), annular SN magnetic pole (8) can adopt permanent magnet or electromagnet to make, annular SN magnetic pole (8) is contained in the shell (2), bearing pedestal (3) is contained on the shell (1), belt pulley (4) is contained in the rotating shaft (5), rotating shaft (5) adopts electric conducting material to make, rotating shaft (5) is contained on the bearing pedestal (3), shell (2) is fixed on the base (1), and cutting magnetic line circle runner is contained between the S utmost point and the N utmost point of annular SN magnetic pole (8), the interior conducting ring (10) of cutting magnetic line circle runner is fixed in the rotating shaft (5), again carbon brush (5) and (7) are contained on the shell (2), and carbon brush (5) is contacted with rotating shaft (5), carbon brush (7) contacts with outer conducting ring (9).
