  OUTDOOR ROTOR ELECTRIC GENERATOR

OBJECT OF THE INVENTION

5 the

The external rotor electric generator that the invention proposes bases its operation on the electric generation by independent poles by means of rotating movement transmission from an outer cylindrical. The electrical generation is carried out by means of permanent magnets installed in a rotor that is also cylindrical, inside of which are the loading coils. fixed on the central axis. The induction of electric field is carried out separately in each phase of work, thus achieving an exact relationship between phases. This structure makes it possible to adjust the offset between these phases, thereby obtaining an increase in useful power in the receiving apparatus over conventional systems and thus causing better operation and considerable saving of electrical energy.

SECTOR OF THE TÉCMCA

fifteen

The external rotor electric generator that the invention proposes is included in the sector of the electric generation technique, more specifically in the generation of electric energy from rotating mechanical movement.

STATE OF THE TÉCMCA

twenty

At present, the electricity generation sector from mechanical sources is monopolized by the alternators, whether they are external induction, self-induced or with permanent magnets, although the latter are less extended for high powers. These types of generators are the most widespread at present for all types of applications, adapted the transmission of mechanical energy to the lipo of energy source and its use with your central axis of rotation typical of conventional alternators.

EXPLANATION OF THE INVENTION

30

The external rotor electric generator that the invention proposes, bases its fixation on a magnet carrier rotor rotating around fixed loading coils to a central axis. Three groups of load coils and their corresponding permanent magnets are distinguished, each group associated to W18 from the three generated electrical phases. The rotary movement is transmitted from an outer cylinder to W1 rotor carrying pennanentes magnets, through crowns and pmones properly studied to multiply the speed of rotation of the rotor. The outer cylinder will be adapted for use with a tileme of auxiliary mechanical energy, adapting in each case to which it is.

More specifically, the external rotor electric generator object of the invention is constituted from a main shaft that supports the fixed parts thereof, these being the pinion carrier plates. the same pine nuts. the bearings and brackets necessary for fixing. On the other hand we have two well differentiated rotating elements, on the one hand the outer cylinder and on the other the inner rolative group, constituted by a cylinder carrying magnets and the front and rear inner rotors. The outer rotor is responsible for collecting the mechanical energy from the external source and transmitting that movement through the two inner crowns housed inside and from the intermediate sprockets to the attack sprockets thus setting the inner rotating group in motion.

The magnet holder cylinder has three groups of permanent magnets that in its motion sweep the loading coils, which jWlto to their respective statues are fixed to the main axis. It should be noted that when the movement of the outer cylinder is transmitted to the inner rotating group through the intermediate pinion assembly, the direction of rotation is in the opposite direction to that of the outer cylinder.

With this opposite movement, permanent magnets cause that, in the maximum load, the set is rejected by the field already created, thus facilitating a better turning effort of the whole assembly.

EXPLANATION OF THE FIGURES

Figure 1 corresponds to the side elevation view duly sectioned of the object of the invention, relative to the electric generator of external rotor.

The main axis (1) is the reference of the immobile part of the generator. On this element all the immovable elements of the invention will be fixed. In this way. The front sprocket plate (2) and the rear sprocket plate (21), which in turn house the intermediate front (4) and rear sprockets (41), are fixed on the main shaft (1). These pinions on the other hand, if they can rotate freely on their axis of fixation to the pinion plates

Also on the main shaft (1), the stators (10), (101) Y (Io '), in turn positioners of the loading coils (11), (11') Y (I I ', are fixed }

On the other hand, the outer cylinder (8) is responsible for collecting the external movement and transmitting it to the mobile loaves of the generator. Therefore, it will be the reference of the entire mobile assembly of the invention.

Said outer cylinder (8) is a carrier inside and integral with the front (5) and rear (51) inner crowns that transmit the rotary movement to the front (4) and rear intermediate gears (41), already mentioned above. and responsible for moving the front (12) and rear (121) attack bolts. The latter are found

mounted on the front (3) and rear (3 ') rotors in solidarity, thus transmitting the movement generated by the outer cylinder (8).

The front inner rotor (3) is coupled to the main shaft (1) by the front bearing (9). That will allow the necessary rotation of the front inner roller (3) on the main shaft (1). Symmetrically at its rear, the inner rear rotor (31), is

coupled to the main shaft (1) by the rear bearing (9 '), thus allowing relative rotation between the inner rotor (31) and the main shaft (l). These front (3) and rear (31) interior rotors are responsible for supporting and transmitting the movement to the cylinder with magnets

(6) which houses the permanent magnets (7), (71) AND (72).

The constituent elements of the machine are the following:

-Main axis (1) - Front sprocket plate (2) - Rear sprocket holder (2 ') - Front inner motor (3) - Rare interior color (31) - Front Intentional Pids (4) -Interedi.os rear pines (41) - Front lower crown (5) - Rear interior crown (51) -Magnet holder cylinder (6) -Pennial magnets phase (7) -Permanent magnets 2J phase (i) -Planning magnets 3J phase (72) -Outer cylinder (8) -Front Roller (9) - Rare Rodamienfos (91) -Stator 1J phase (10) -Stator 2nd phase (101) -Stay, 3 'phase (it') - 1 J phase loading coils (11) - 2J phase loading coils (11 1) - 3 'phase (ll') charging reels -Front attack pinion (12) -Back attack pinion (121)
