Permanent magnets (12) are used to perform useful work. The field of a first permanent magnet (12) is diverted by electromagnetic coils (22, 24) to such a low value that another opposing permanent magnet (20, 26, 52) can approach the first magnet (12) withoutthe application of undue force. The field in the first magnet (12) is restored to act on the second magnet so as to repel it. The force which results may be harnessed to effect reciprocal or rotary motion. |

Un couple de bobines (1, 2) est employé avec aimant permanent (3) interposé sur arbre (5) supporté à chassis (4), sur couple de roulements (6, 7) et, dans la partie supérieure, équipé avec contacteurs disjoncteurs (8) à balais tournants (9, 10) à secteurs annulaires et profil de contact, aux deux balais glissants (14,15) connectés aux dites bobines (1, 2) de partie fixe, avec parties d'interruption contreposées. Moyennant les dits balais tournants (9, 10) le courant pris d'un distributeur (13) et par des conduits intérieurs (11, 12) du contacteur disjoncteur (8), parvient aux deux balais glissants (14, 15) et cependant aux bobines (1, 2) déterminant une fréquence magnétique qui met en rotation l'aimant permanent (3) et donc le corps de rotation. Lorsque les balais glissants (14, 15) se trouvent sur les parties d'interruption du profil de contact, le passage du courant est interrompu pour un instant et, pendant que le corps de rotation poursuit son mouvement, passant la phase critique par inertie, une inversion de polarisation est générée dans le flux magnétique opérant un effet ultérieur de rotation. Le distributeur (13) peut etre intégré à nouveau avec la quantité minime d'énergie cédée pour le démarrage au moyen de dérivations de bobines de régénération (16, 17). L'appareil peut etre employé pour universalité d'utilisation: pour produire énergie sous tension, ou bien pour être emploié comme groupe moteur. |

| On a rotor (6;8) which is fixed to a rotatable rotating shaft (4), a plurality of permanent magnets (22A-22H) are disposed along the direction of rotation such that the same magnetic pole type thereof face outward. In the same way, balancers (20A-20H) are disposed on the rotor for balancing the rotation of this rotor. Each of the permanent magnets is obliquely arranged with respect to the radial direction line of the rotor. At the outer periphery of the rotor, an electromagnet (12;14) is disposed facing this rotor, with this electromagnet intermittently energized based on the rotation of the rotor. According to the magnetic rotating apparatus of the present invention, rotational energy can be efficiently obtained from permanent magnets. This is made possible by minimizing as much as possible current supplied to the electromagnets, so that only a required amount of electrical energy is supplied to the electromagnets. <IMAGE> | ||||||

| PROBLEM TO BE SOLVED: To prevent the lowering of torque and the number of revolution even when the number of turns of a coil is increased and a current is reduced, by variably controlling the frequency of the commutation or interruption of an applied output independently without using the rotational-position information of the shaft of a motor. SOLUTION: A rotary switch 4 is formed in a shape that nine rings in total are fixed to a shaft 41, a pulley 42 is installed to the shaft 41 and a belt is stretched between the pulley 42 and a pulley 22 mounted on the shaft 21 of an auxiliary motor 2, and the shaft 41 of the rotary switch 41 can be rotated by turning the auxiliary motor 2. The DC output of a battery 3 is commutated by revolving the rotary switch 4 by the auxiliary motor 2 and the coils of each phase of a motor 1 are supplied with the commutated DC output and the coils are rotated, but the frequency of the commutation of a current fed to the coils of each phase can be controlled by adjusting the number of revolution of the auxiliary motor 2 at an arbitrary value. Accordingly, the number of turns of the motor is increased, and the current is reduced while the lowering of the number of revolution and torque can be prevented. | ||||||

| PURPOSE: To supply an inductor coil with a rectangular wave or sine wave of a specific frequency, in synchronism with a rotor and control it by providing at least one oscillator which displays the position of the polarity of a rotor, a sensor which detects whether or not the oscillator is present when the oscillator rotates to pass together with the rotor, and a power source and a coil which are connected to the sensor. CONSTITUTION: An oscillator 15 is mounted on a drive shaft 14 and combined with the sensor 17 which detects whether or not the oscillator is present, when the oscillator passes at the time of motor rotation. An inverting circuit 18 is controlled by the combination of the oscillator 15 and sensor 17 to generate the frequency of the rectangular wave or sine wave, in synchronism with the rotation of the rotor irrespective of the speed of the motor and the load on the motor. Consequently, a conventional commutator and a relative brush can be removed, and the effects of the frequency of a source current can be eliminated. | ||||||

| PURPOSE: To allow members to make a rotary motion or other motions using energy of a permanent magnet. CONSTITUTION: This device is provided with a permanent magnet 22, having an N and an S-pole, a coil 24 wound around the permanent magnet 22 between the N and the S-pole, and a DC power supply 28 and a switching means which are serially connected to the coil 24, and a control circuit 26 for controlling the opening and closing of the switching means. | ||||||
| 136 | Moving magnetic field type permanent magnet motor | JP23022191 | 1991-09-10 | JPH05236719A | 1993-09-10 | NOMURA TAKASHI |
| PURPOSE:To obtain a self-traveling moving magnetic field type permanent magnet motor which can be easily started by providing drive mode switching means for switching a starting operation to a self-driving operation when a rotating speed of a rotary shaft becomes a predetermined speed. CONSTITUTION:When a SW 78 is closed, currents flow to coils A-D through a starting controller 50, a moving magnetic field is generated by a shading coil 10, and a rotor 40 is started. When a rotating speed of a rotary shaft 30 becomes a predetermined speed or more, a weight 72 is displaced outside by a centrifugal force of the shaft 30, a joint 73 is shortened, a slidable cylindrical member 74 is moved to a leftside, and a bridgelike arm 75 is moved to the leftside. Accordingly, a brush retainer 76 is moved leftward to drive a self- driving controller 60. Simultaneously, as the retainer 76 is moved leftward, a response switch 77 is operated to open a power switch 78 and to close a load side switch 79, thereby switching a starting operation to a self-driving operation. Therefore, an energy saving motor which can be easily started and self-driven is obtained. | ||||||

| PURPOSE: To improve stop position accuracy of permanent magnet by switching power supply such that magnetic fields for attracting each permanent magnet are produced from coils arranged at the opposite sides of a stator opening facing with the polarity inverted portion of the permanent magnet, at a position where the permanent magnet stops after rotation. CONSTITUTION: A permanent magnet 3 stops at a position where S-pole of the permanent magnet 3 faces with N-poles of first and fourth protrusions 7a, 7d and N-pole of the permanent magnet 3 faces with S-pole of second and fifth protrusions 7b, 7e. When the permanent magnet 3 over rotates through inertia, S-pole of the permanent magnet 3 faces with S-pole of the second and fifth protrusions 7b, 7e thus producing leftward rotary torque in the permanent magnet 3. When the permanent magnet 3 over rotates leftward, it is subjected to repelling magnetic field of the first and fourth protrusions 7a, 7d. Consequently, correcting force functions such that the polarity inverted portion of the permanent magnet 3 faces with the center between the openings 7g, 7j of stator 7.

| 138 | Magnetic excitation type induction motor | JP6493489 | 1989-03-16 | JPH0232741A | 1990-02-02 | RI SOUSHIYOU |
| PURPOSE: To realize a simple and small construction, by a method wherein a rotor is placed between two crescent-type stators whose thicknesses are thick at the center parts and thinner toward the tip parts. CONSTITUTION: An AC current is applied through brushes 7 and commutators 6. If one pole point is excited to be an S-pole, the tip part 8 of a crescent-type stator 2 opposite to the pole point is excited to be an N-pole. If the phase of the applied AC current is commutated, the pole point is excited to be an N-pole and a mutual repulsive force is produced between the pole point and the tip part 8 of the crescent-type stator 2. Then, the rotor 1 is turned counter- clockwise and, at the same time, the tip part 8 of the crescent-type stator 2 is excited to be S-pole. Then, after the pole point comes to this position, if the polarity is commutated again, a repulsive force is applied to the rotor 1 to turn the rotor l further. By repeating these processes, an induction motor continues to rotate. COPYRIGHT: (C)1990,JPO | ||||||

| PURPOSE: To obtain a magnet which inverts its polarities when applied with a sufficiently strong magnetic field and recovers to the same polarities when the magnetic field is removed by using a magnet composition consisting of strontium hexaferrite containing strontium metal ferrite. CONSTITUTION: A magnet raw material is formed by mixing a specific amount of chromium oxide with strontium hexaferrite which is already constituted. The mixture of chromium oxide and ferrite is crushed into particulate mixture, which is formed in the shape of a magnet and then burnt at 1250°C. The chromium oxide and strontium hexaferrite chemically react on each other at high temperatures to produce a compound which has different crystal structure from strontium hexaferrite. This compound is octagonal corandom crystal represented by (Fe 0.6+Cr 0.4) 2O 3. COPYRIGHT: (C)1990,JPO | ||||||
