[0001] The present invention relates to a motor, a generator, and an electromagnetic device used alone or in combination with a magnet or an electromagnet. And a combination thereof.

[0002]

2. Description of the Related Art Conventional stators and wound-type rotors of generators and electric motors are manufactured by incorporating windings into slots provided for inserting windings in laminated magnetic steel sheets. . Highly costly due to extremely complicated and complicated work such as connecting the winding ends after winding, forming and fixing the end coil, the work process is long, and reliability such as insulation breakdown during use due to scratches during work etc. Performance, the entanglement and interference between narrow slots and windings, the slot space factor to improve the workability of wire assembly work (typically 50%), the cost increase due to the extension of the end coil, and so on This has led to a decrease in efficiency and a decrease in output due to an increase in resistance loss of the end coil portion and an increase in leakage magnetic flux. In addition, the mechanization of production is difficult, and if it is carried out, equipment costs are high. Further, in the case of a low-voltage or medium-large-capacity electric machine, the diameter of the winding is increased, so that the workability is further deteriorated and the cost is further increased. In order to reduce the starting torque of the electric motor or the generator, the laminated iron cores of the stator and the rotor are skewed while being shifted straight or zigzag in the circumferential direction. In this case, the slot cross-sectional area is reduced, and workability such as die-casting work of the winding and the rotor is further deteriorated. In addition, it is difficult to insulate the windings and phases between high-voltage devices and other parts.If this is done using conventional core windings, the size of the laminated core must be increased and the area of the slots must be increased. And the cost was greatly increased. In addition, the conventional iron core winding structure used in an ultra-high temperature environment is limited to 200 ° C at the combined temperature of the ambient temperature and the temperature rise of the coil. Materials such as ceramics having high heat resistance have to be used for all parts such as bearings and bearings. Attempting to achieve this is accompanied by a large increase in the slot area, which is costly and technically impossible.

SUMMARY OF THE INVENTION Accordingly, the present invention simplifies the winding structure by the core structure, material, and structure by using the windings of the stator and rotor of an AC generator, an electric motor, and the like, and the core structure and structure thereof. It is an object to solve the problems such as simplification of start-up improvement, realization of a multifunctional electric machine, realization of a high heat resistant electric machine, and the like.

[0004]

Means for Solving the Problems In order to simplify the winding structure of the stator and the rotor of an AC electric machine, for example, the winding is made of a bobbin or the like. A magnetic core can be formed by the above structure, and an eddy current is small in the AC magnetic field, and the core is designed to be easy to work.The material is made of sintered iron or laminated iron core of electromagnetic steel sheet・ Compose and create. This makes it possible to provide a stator and a rotor that are simple in winding operation, have high reliability, are inexpensive, and are suitable for mass production. In addition, the magnetic pole portion has a protruding magnetic pole structure to form a spatial or overlapping structure with other phase magnetic poles in order to realize a stator and a rotor for polyphase alternating current, so that electromagnetic coupling between the phases can be further improved. At the same time as strengthening, the organic separation, dispersion, and arrangement of each phase magnetic pole can be performed, for example, to effectively form a rotating magnetic field. Furthermore, by applying another phase winding to each phase winding in order to strengthen the further electromagnetic coupling between the phases, a motor with high efficiency and low vibration noise can smoothly form a magnetic field such as a rotating magnetic field. Can be realized. Although it is a simplification of start-up improvement, each magnetic pole and each phase magnetic pole are shifted linearly or zigzag in the circumferential direction by using a bobbin structure electromagnet, so that they are easily provided on the stator or the rotor independently or in each other. It becomes possible. Regarding the realization of a multifunction electric machine, it is possible to configure a single machine by forming a plurality of stators or rotors of an electric motor or a generator in the axial direction using a bobbin structure electromagnet. These components can be used alone, in combination, or in combination.
It becomes a generator motor, and can smoothly switch between economical operation depending on a change in capacity or load. For example, incorporating multiple generators into a wind power generator with a lot of power fluctuations, selecting the number of generators to be operated according to the wind intensity, and stabilizing the power generation voltage or short-circuiting all generators when locking in strong winds It can be done effectively. Regarding the realization of a high heat resistant electric machine, using a bobbin structure electromagnet to apply it to the stator or rotor of a motor or generator, use a high heat resistant material such as ceramic for the insulating material, It is possible to configure and realize the element parts without using a heat-resistant material for the bearing and using a flammable lubricant such as oil or grease such as a magnetic bearing or an air bearing for the bearing. The winding frame of the winding has a simple bobbin structure, and the material is formed of ceramic.The inner and outer lead wires are made of ceramics that can be used in high-temperature environments by using ceramic insulators for insulation. Can be realized. By the way, it is 200 ° C at the highest temperature currently used, but 400 and 500 ° C is not a dream with proper selection of materials. In this case, it is not necessary to use an electromagnetic steel sheet etc. in consideration of eddy current such as iron core. Even iron and iron castings are good. For the insulation of the winding, it is necessary to use a material having excellent heat resistance such as a glass coating or a glass fiber tube, and further, to use a tube of an alumina fiber at a high temperature of 500 ° C. or more. When the temperature of the copper wire also becomes high, it is necessary to change to a carbon fiber conductor.
