Device for increasing the force of mechanical movement in a stator-rotor system by the interaction of permanent magnet magnetic fields

Abstract

The invention relates to mechanical engineering and is intended for increasing the force of mechanical movement of a rotor in a stator-rotor system. The invention can be used for domestic, industrial and public needs. The claimed device comprises a source of external force, a stator, a rotor, a group of permanent magnets, and a resilient fastening mechanism. The sources of an increase in the force of mechanical movement of the rotor are: the force of connection between the magnetic fields of the permanent magnets, a force that restores the symmetrical interaction of parts of the magnetic fields of the permanent magnets, and the capacity of permanent magnets to restore the shape, strength and direction of their magnetic field when interaction with the magnetic field of another magnet ceases. Asymmetrical interaction of the magnetic fields of rotor magnets with the magnetic fields of stator magnets prevents the device from assuming a state of equilibrium, therefore increasing the force of mechanical movement of the rotor.

Description

The stator magnet (5) (Fig.9) is located within the boundaries of the projected rotor magnet motion path (12). The boundaries of the stator magnet neutral line (Fig.9) may be located at a difference distance with respect to the rotor rotation axis L3 < L4. In this case the stator magnet neutral line forms an angle (14) to the projected neutral line motion path of rotor magnets (4.1, 4.2 and 4.3), thus increasing the asymmetry of interaction between the magnetic fields of the rotor and stator magnets since the magnetic field force increases towards the magnet pole ends and decreases towards the magnet neutral line. The rotor centrifugal force F is calculated by the formula: F=3(F1 + F2 + F3) + F5. The rotor magnets (4.1, 4.2 and 4.3) interact with other stator magnets (5.1, 5.2 and 5.3) in a similar way. Therefore, there is cyclical interaction between magnetic fields of rotor magnets and magnetic fields of stator magnets resulting in the rotor centrifugal force increasing mechanical motion force in the stator-rotor system. (Fig.la - 1b) show the embodiment of the device with the rotor magnets (4) and the stator magnets (5) symmetric with respect to the rotor rotation axis (2). (Fig.2) shows one of the embodiments of the device for increasing mechanical motion force in the stator-rotor system by cyclical interaction between magnetic fields of permanent magnets using the gravitational force F4. In this embodiment, the rotor center of gravity (16) does not coincide with the rotation axis (2). As the rotor center of gravity (16) moves from the highest point of the rotor center of gravity (18) to the lowest point of rotation (19), the gravitational force F4 acts on the rotor cylinder generatrix. The rotor is accelerated resulting in the inertial movement of the rotor center of gravity (16) from the lowest point of rotation (19) to the highest point of rotation (18) after the center of gravity (16) passes the lowest rotation point of the rotor (19). Due to the law of conservation of energy, the rotor center of gravity (16) cannot reach the highest rotation point (18). In this position, the magnetic field of the rotor magnet (4.1) (Fig.4) is affected by the magnetic field of the stator magnet (5). Further interaction of magnetic fields of the stator and rotor magnets occurs similarly to the abovedescribed embodiment. The rotor centrifugal force F is calculated by the formula: F = 3(F1 + F2 + F3) + F4 + F5. The device base (1), the rotor cylinder generatrix (3), the stator magnet mount (7), and the rotor balancing weight (17) are made of a material not interacting with magnetic fields of permanent magnets, or interacting insignificantly. The device may be designed so that interacting groups of magnets are located at different distances relative to the rotor rotation axis. The number of interacting groups of rotor and stator magnets may differ, and magnets may interact through their magnetic fields simultaneously or alternately. The energy generated as a result of the increasing mechanical motion force of the rotor is transmitted by any known method including through a soft or rigid connection with a gearbox or generator. In addition, magnetic fields of rotor magnets may be used to obtain induced electric current. For this purpose, electric generator windings are placed along the motion paths of rotor magnets to obtain induced electric current when they are intersected by magnetic fields of rotor magnets. Increasing mechanical motion force in the stator-rotor system by interaction between magnetic fields of permanent magnets is confirmed by a practical experiment. The experimental device was manufactured in accordance with (Fig. 2). The device base (1) is an AISI 304 stainless steel frame, the rotor rotation axis (2) is a freely rotating sleeve secured to the device base. The rotor cylinder generatrix (3) is made of aluminum and has a diameter of 420 mm. The rotor permanent magnets are neodymium magnets in the form of 20x40 mm rods weighing 90 g - 3 pcs. The stator permanent magnet is a neodymium magnet in the form of a 75x20x5 mm rectangle. An additional weight is lead plates with a total weight of 160 g. In order to obtain an external force of the same value required to maintain the experimental integrity, a device is located in the rigid mounting area of the rotor magnet (4.2), which coincides with the rotor center of gravity (16), to secure the additional weight on the rotor cylinder generatrix during the motion from the highest rotation point of the rotor (18) to the lowest point (19). The additional weight comes off the rotor cylinder generatrix at the lowest rotation point of the rotor (19) by gravity. In the experiments, the rotor cylinder generatrix was located at an angle of 20 degrees to the Earth's surface. There are 3 permanent neodymium magnets installed on it with their south poles directed towards the rotor rotation axis. The distance from the rotor magnet neutral line to the rotation axis is 235 mm. The distance between rigid mounts of rotor magnets is 60 mm. The rotor center of gravity (16) is located at the rigid mount of the rotor magnet (4.2). The stator magnet is located at the highest rotation point (18). The stator magnet is secured using an elastic fiberglass material. The north pole of the stator magnet is directed towards the rotor rotation axis. The distance from the stator magnet neutral line to the rotation axis is 245 mm. The experiment consisted of 2 parts. In the first part, there was no stator magnet. The additional weight was placed on the rotor cylinder generatrix, at its center of gravity (16). The rotor center of gravity was shifted in the direction of rotation by 45 degrees from the highest rotation point (18). In this position, the rotor began to move. The additional weight came off at the lowest rotation point of the rotor (19). The rotor experienced a certain force sufficient to overcome the highest rotation point (18) and made one full revolution around its axis. On the second revolution, the rotor center of gravity could not reach the highest rotation point of the rotor (18) due to the law of conservation of energy, so the rotor moved in the opposite direction. Therefore, the rotor made one full revolution around its axis. In the second part of the experiment, the stator magnet was placed along the rotor magnet motion at the highest rotation point (18) as described above. Similar to the first part of the experiment, an additional weight was placed on the rotor cylinder generatrix at its center of gravity (16). The rotor center of gravity was shifted in the direction of rotation by 45 degrees from the highest rotation point (18). In this position, the rotor began to move. The additional weight came off at the lowest rotation point of the rotor (19). The rotor experienced a certain force sufficient to overcome the highest rotation point (18) and made three full revolutions around its axis. On the fourth revolution, the rotor center of gravity could not reach the highest rotation point (18) due to the law of conservation of energy, so the rotor moved in the opposite direction. Therefore, the rotor made three full revolutions around its axis. The comparison of the results obtained shows improved efficiency in the stator-rotor system — the gravitational force in this case — by at least 3 times. The experiment was conducted 75 times and the same results were obtained in all cases. This is a practical confirmation of the technical result declared, namely: increasing mechanical motion force in a stator-rotor system by interaction between magnetic fields of permanent magnets.
