[0002] The invention is known as three-phase infinity windings. The invention is applicable to AC machines, i.e., three-phase windings, and is intended for both generator windings and motors, and the generator with an infinity winding can be used in hydroelectric power plants and wind turbines.

[0003] The closest prototype to the claimed invention in technical essence is an axial generator. Three-phase infinity windings consist of a rotor, permanent magnets, a stator and windings, the rotor has the shape of a disk on which permanent magnets are located, and the permanent magnets are located on the rotor with opposite poles, the number of permanent magnets on the rotor is arranged in such a way that three permanent magnets intersect with each winding simultaneously, the north pole of the permanent magnet intersects one side of the infinity winding, the south pole intersects the middle side, and the other north pole intersects the other side of the infinity winding, the windings are wound along the stator slots and have the shape of infinity, one infinity winding is wound in three stator slots, and one end of the wire is inserted into the first slot from above and reaches the bottom of the slot, the same end of the wire is inserted into the second slot from below and reaches the top of the slot,the same end of the wire is inserted from above the third slot and is pulled through the bottom of the slot, reaching the bottom, the wire is inserted from below the second slot and reaches the top of the second slot, reaching the top of the second slot one turn is completed. The north pole of the permanent magnets intersecting the infinity winding crosses one side of the winding, the south pole crosses the middle side of the winding, and the other north pole crosses the other side of the winding, causing the formation of current. A known disadvantage of the generator is that the stator windings are single-phase. A generator equipped with single-phase windings is used only when operating devices that can consume little electricity. (AZF20240010. H02K19\00. 10.06.2024.) In the presented generator, a three-phase infinity winding is wound on the stator slots, the first winding of the first phase is wound on the 1st, 2nd and 3rd stator slots, and the second winding of the first phase is wound on the 4th, 5th and 6th stator slots,the first winding of the second phase is wound on the 2nd, 3rd and 4th slots of the stator, and the second winding of the second phase is wound on the 5th, 6th and 1st slots of the stator, the first winding of the third phase is wound on the 3rd, 4th and 5th slots of the stator, and the second winding of the third phase is wound on the 6th, 1st and 2nd slots of the stator, to eliminate the drawback, the generator is equipped with single-phase windings.

[0004] Three-phase infinity windings consist of a rotor, permanent magnets, a stator and windings, the rotor has the shape of a disk on which permanent magnets are located, and the permanent magnets are located on the rotor with opposite poles, the number of permanent magnets on the rotor is arranged in such a way that three permanent magnets intersect with each winding at the same time, the north pole of the permanent magnet intersects one side with the infinity winding, the south pole intersects the middle side, and the other north pole intersects the other side with the infinity winding, the windings are wound along the slots of the stator and have the shape of infinity, one infinity winding is wound in three slots of the stator, and one end of the wire is inserted into the first slot from above and reaches the bottom of the slot, the same end of the wire is inserted into the second slot from below and reaches the top of the slot, the same end of the wire is inserted from above the third slot and is pulled through the bottom of the slot, reaching the bottom,the wire is inserted from the bottom of the second slot and reaches the top of the second slot, reaching the top of the second slot one turn is completed, a three-phase infinity winding is wound on the stator slots, the first winding of the first phase is wound on the 1st, 2nd and 3rd stator slots, and the second winding of the first phase is wound on the 4th, 5th and 6th stator slots, the first winding of the second phase is wound on the 2nd, 3rd and 4th stator slots, and the second winding of the second phase is wound on the 5th, 6th and 1st stator slots, the first winding of the third phase is wound on the 3rd, 4th and 5th stator slots, and the second winding of the third phase is wound on the 6th, 1st and 2nd stator slots. In the presented generator, the windings wound on the stator slots are wound in the form of infinity. Each infinity winding is wound on three stator slots. One end of the winding wire is inserted into the groove from above the first stator groove and pulled to the bottom of the groove, this end of the wire is inserted into the groove from below the second stator groove and pulled to the top of the groove,this end of the wire is inserted into the slot from above the third slot of the stator and reaches the bottom of the slot, the end of the wire reaching the lower side of the third slot of the stator is inserted into the slot from the lower side of the second slot, pulled to the upper side of the second slot and delivered to the upper side of the first slot and the infinity winding is repeated in such a sequence. To wind the first winding of the first phase, the winding wire is wound in the form of infinity in the 1st, 2nd and 3rd slots of the stator. To wind the second winding of the first phase, it is wound on the 4th, 5th and 6th slots of the stator, as a result of which both windings of the first phase are connected. The subsequent winding of the first winding of the second phase is wound in the form of infinity on the 2nd, 3rd and 4th slots of the stator wire. The second winding of the second phase is wound on the 5th, 6th and 1st slots of the stator, as a result of which both windings of the second phase are connected. The first winding of the third phase is wound on 3,4 and 5 stator slots from the next winding wire in the form of infinity. The second winding of the third phase is wound on the 6, 1 and 2 stator slots, as a result of which both windings of the third phase are connected. The first phase is wound on slots 1, 2, 3, 4, 5, 6 of the stator. The second phase is wound on slots 2, 3, 4, 5, 6, 1 of the stator. The third winding is wound on slots 3, 4, 5, 6, 1, 2 of the stator. Three-phase windings are wound on the stator slots in the specified order. To obtain current from the three-phase windings, the permanent magnets crossing the windings must pass through the three-phase windings according to this rule. To obtain a sinusoidal signal, the permanent magnets are located on the rotor with opposite poles. The permanent magnets in the rotor are arranged so that each winding is crossed by three permanent magnets at the same time, three permanent magnets are crossed simultaneously with the winding in the form of infinity. When the north pole of the permanent magnet is in front of the 1st slot,the south pole of the permanent magnet should be in front of the 2nd slot, and the north pole of the permanent magnet should be in front of the 3rd slot respectively, in addition, the south pole of the permanent magnet should be in front of the 4th slot, the north pole - in front of the 5th slot, and the south pole - in front of the 6th slot. The distance between the permanent magnets located on the rotor is determined by the size of the stator slots, that is, the width and length of the permanent magnet should be equal to the width and length of the stator slot. The north pole of the permanent magnets crossing the winding is located on one side of the winding, the south pole is on the middle side of the winding, and the other north pole is on the other side of the winding. The intersection of three permanent magnets with one winding causes high inductance of the winding,which results in an increase in current. A higher current is obtained by equipping the generator with three-phase infinity windings. By strictly following these rules, three-phase sinusoidal signals can be obtained and three-phase motors and three-phase devices can be powered. The invention was developed for three-phase windings of a generator and a three-phase electric motor, and a generator equipped with infinity windings can be used in hydroelectric power plants and wind turbines. The purpose of the invention is to equip a generator with three-phase infinity windings.
