TECHNICAL FIELD

The invention refers to a generator with permanent magnets and a magnetic field rotating externally relative to the axis of the rotation and which, to a limited extent, produces electrical energy in the form of alternating current at a frequency of 50 Hz for domestic and industrial needs.

BACKGROUND OF THE INVENTION

Generators, designed on the basis of Faraday's law which follows the research made by Pacinoti and his infamous ring, are well known but the solutions, so far offered, fail to propose a generator operating with one magnetic field and a static coil.

DESCRIPTION OF THE INVENTION

The main feature of the generator is that a single magnetic field passes through a coil in order to generate an alternating current. The coil remains stationary and a series of permanent magnets, suitably located in conformity with an aluminum ring, intersect the coils, which are attached to a stator, with the field they generate.

The generator consists of:

- aluminum rotor 1, the interior of which firmly holds permanent magnets 3 which are sized and positioned at 90° one to another;

- stator 2, composed of sheet metal plates connected to a shaft 6 remains static when the motor runs;

- permanent magnets 8, suitably located and conforming with the aluminum ring, which is connected with the rotor 1 via a mechanical interlock and which are positioned at 45 ⁰ one to another;

- coils 4, through which the magnetic fields, generated by the magnets themselves, pass;

- flange 5, mechanically connected to the rotor 1 which also functions as a nest for the two bearings which permits the rotational motion of the rotor 1 on shaft 6 which remains static; - shaft 6 is made of carbon steel and has the function of a support for the generator and also an axis for the rotation of rotor 1 with the help of cylinder roller bearings;

- two cylinder roller bearings 7 which allow the rotation of the rotor 1 on shaft 6. The bearings conform with the shaft by means of nuts and safety rings.

- two supporting groups 8, made of construction steel and holding the two ends of the shaft 6. These supports are mechanically connected with welded construction, the purpose of which is to support the entire apparatus and to make it a durable, easily transportable and safe.

- two cog wheels 9 made pf steel with slanted teeth curved in both directions which serve to transmitting torque without slipping thus forming a Chevron-type gear transmission which reverses the direction of the rotation given set by the rotating input sector.

- assembly board 11 for system startup via energy supplied by four rechargeable batteries 13;

- assembly board 12 which differentiates the generated energy from the magnetic field from which one part is sent to the batteries to maintain their charge level.

EXAMPLES OF THE PRACTICAL REALIZATION OF THE INVENTION

According to the here-presented invention the motor-generator has a magnetic field passing through 4 coils to generate alternating current. On the output of each coil 4 two electrical connections are mounted to transfer the output electrical energy: one of the connections ensures the link with the motor the other - with the generator. The inside of the aluminum rotor 1 of the motor-generator securely hosts the permanent magnets 3, which are adequately sized and positioned at 90° one to another. The permanent magnets 8 are connected to the rotor 1 by a mechanical interlock and are positioned one to another at 45. The stator 2 is made of tin lamellae and is connected with the shaft 6, which remains immobile when the motor is running. The rotor 1, which also functions and the nest for two bearings, is connected mechanically to the flange 5. These two bearings ensure the rotary motion of the rotor 1 on shaft 6 which is static. The shaft 6 is made of carbon steel and performs the function of the supporting structure of the generator as well as the function of an axis for the rotation of rotor 1, via the cylinder roller bearings 7. The bearings 7 allow for the rotation of the rotor 1 on shaft 6 and conform to it with the help of nuts and safety rings. The two ends of the shaft 6 lie on two support groups 8, made of construction steel. These supports 8 are mechanically connected with a welded construction, the purpose of which is to support the whole apparatus and to make it durable, easy to handle and safe. The steel cog wheels have teeth 9, slanting in two directions and serving transfer the torque without slipping thus forming a Chevron-type gear, which reverses the direction of the rotation given by rotating the input unit. One of the cog wheels 9 is attached to the outside of the rotor 1 through mechanical fastening and the other - to the electricity generator. The assembly board 11 is connected to the batteries 13 and serves to start the system with energy from the batteries. Assembly board 12 distributes the generated energy from the magnetic field: one part of the energy is sent to the batteries 13 to maintain their charge.
