Abstract

<P>PROBLEM TO BE SOLVED: To save energy by rotating a multiple-shaft motor more efficiently. <P>SOLUTION: Rotors made of a magnetized permanent magnet are coupled and interlocked with two or more gears. Openings are formed up to the closest points of the N and S poles, where the magnetic poles attract each other to rotate the motor, and the portions thereafter are blocked by partitions and coils wound on iron cores. The motor is rotated by the attracting forces of different magnetic poles of the rotors by conducting the coils, by the rotation caused by the magnetic force of the coils, and by combined forces into the rotating direction, since the coils of the fixed magnetic fields separated by the partitions are divided in half so that, when one side coil is conducted, a current flows in the other side coil. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

Detailed Description of the Invention

Industrial application fields

  A motor has been devised in which a rotor with multi-axis permanent magnets is connected to a gear to rotate it, but without increasing the number of fixed field coils, it is at a position where different magnetic poles attract and where the same magnetic pole repels. By combining the permanent magnet rotor, it is possible to obtain a more efficient rotational force by combining the attractive force and the repulsive force.

  In a motor structure, a rotor magnetized with two or more permanent magnets is connected to a gear and rotated. Therefore, when the structure is complicated and the manufacturing cost is compared with the supplied output, one rotor is closer to the rotor. had. I think that the way of use will open if it becomes higher output.

Problems and Means to be Solved by the Invention

  Combining multiple rotors magnetized with permanent magnets so that they are linked by gears, the force attracted at the point where the different magnetic poles of N and S poles are closest to each other becomes the largest and stops. Therefore, the attracting magnetic force generated by supplying a current to the coil and fixing the coil wound around the partition or iron core in the latter half of the center point where the magnetic pole of the rotor is closest, and the force at which the different magnetic pole attracts in the first half And it continues to rotate with the combined force of the permanent magnet rotor that repels the same magnetic pole. If the gap between rotors and the opening are made narrower, the efficiency will be improved, but it is necessary to devise measures for the force applied to the bearing due to the breaking of axial symmetry.

Action

  When two or more rotors magnetized with permanent magnets are linked and interlocked with a gear, the opening is located at the closest point where the N and S poles are attracted and rotated. The coil is closed by a coil wound around the core, and the coil is divided into two parts by separating the partition with a force that attracts the different magnetic poles of the rotor by attracting the coil and rotation by the magnetic force of the coil. When one coil is energized, current flows through the other coil, which rotates by combining the forces in the direction of rotation. By combining a rotor magnetized with permanent magnets so that the same magnetic poles repel each other at a predetermined position of the connected rotor, a more efficient rotational force can be obtained and it can be rotated with less energy consumption. .

As an example of the first term of the present invention, we will explain a DC motor in which a rotor magnetized with a permanent magnet is linked and rotated by four gears. FIG. 1a is a schematic cross-sectional view (the gear is at a position away from the rotor). The four rotors (6), (7), (8), and (9) are at predetermined positions on the extension of the rotating shaft. The gears are fixed to each other, meshed, and each rotor shaft is rotatably supported by a bearing, front part bracket and rear part bracket so that the four rotors rotate simultaneously. From the intermediate part where the outer peripheral tips of the rotors (6) and (7) are closest to the latter half in the rotational direction, the bulkhead (10) and the fixed field coil are separated by separating the same number of coils across the bulkhead. When energized, the induced current is used in a combination in which no voltage is applied to the other coil. Etc. are fixed to the yoke of (1) and the front bracket and the rear bracket, and also to the latter half in the rotational direction from the closest intermediate part of the outer peripheral tip of the rotors (7) and (8). This is a structure in which the partition wall (10) and coil are fixed to the yoke and front / rear bracket (1). The rotor (9) rotates at the same time with the same magnetic poles repelling across a position centered on the boundary between the latter half of the rotation direction of the fixed field coil adjacent to the rotor (8) and the open portion. Combine as follows. (13) is a magnetic detection element that is connected to the fixed field coil (16-A) (17-B) via a transistor.
FIG. 1 b is a partial cross-sectional view seen from an oblique direction. FIG. 1c is a schematic wiring diagram. When there is a rotor magnetized with a permanent magnet at the position of FIG. 1a, when a predetermined (+) (−) DC voltage is applied to the power supply terminal, the magnetic detection element (13) Detects the south pole of the rotor (8), applies a positive voltage to the base of the transistor (T-1), the transistor of (T-1) conducts, and the field coils (16-A) and ( 17-B) is energized, and the rotors (6), (7), (8) and (9) have their adjacent rotors rotating in opposite directions. Immediately, the magnetic detection element (13) detects the north pole of the rotor (8), applies a positive voltage to the base of the transistor (T-2), and the (T-2) conducts, whereby the field coil (16- B) and (17-A) are energized and continue to rotate, and then (13) the magnetic detection element detects the south pole of the rotor (8) and gives a positive voltage to the base of the transistor (T-1). The rotation continues in sequence, and the force that attracts and repels the magnetic poles of the permanent magnets between the rotors acts in the direction of rotation.
In this description, the explanation is made with the drawings in which four rotors magnetized with permanent magnets are connected. However, the rotor rotates in the same way as this description by connecting the rotors with the same number of N and S poles. To do. It can be used for anything as long as there is enough space. In addition, we think that it is promising for the power of transportation such as electric cars, because it consumes less energy and provides a great deal of power.

These are the longitudinal cross-sectional views of the embodiment of the motor which made the 4 permanent magnet rotor parallel. These are the partial sectional views seen from the slanting upper surface. These are the electrical wiring diagrams of an embodiment outline.
