摘要： A magnetic slot wedge inserted in each slot of a stator core of a dynamo-electric machine so as to close an opening of each slot for preventing coils embedded in each slot from getting out of each slot is disclosed. The slot wedge includes a first thin non-magnetic sheet such as a polyester film having the thickness of several ten microns or an aromatic aramid paper, an amorphous sheet bonded to one of two faces of the first non-magnetic sheet opposite the other face facing a coil side in the condition that the wedge is inserted in each slot, and a second thin non-magnetic sheet bonded to the amorphous sheet so as to cover it. Each non-magnetic sheet has such dimensions that each non-magnetic sheet is projected from both ends and both side edges of the amorphous sheet.

摘要： A slot insulating magnetic wedge inserted into the vicinity of the center of an opening portion of a stator slot, the slot insulating magnetic wedge being contacted with an inner surface of the stator slot of a motor. The slot insulating magnetic wedge comprises a non-magnetic insulating thin leaf shaped material and a magnetic material layer laminated on at least one surface of the non-magnetic insulating thin leaf shaped material, the electric resistance of the magnetic material layer being in the range from 10 .mu..OMEGA..cm to 200 .mu..OMEGA..cm. The magnetic material layer comprises an amorphous magnetic alloy thin film, a Fe-based magnetic alloy thin ribbon having ultra fine crystalline particles, a crystalline magnetic alloy thin ribbon, a crystalline or amorphous magnetic alloy thin film produced by thin film forming technologies, or the like. The magnetic material layer with the electric resistance in the range from 10 .mu..OMEGA..cm to 200 .mu..OMEGA..cm is used as a magnetic wedge thereby to remarkably improve the efficiency of the motor. Since the construction of the magnetic wedge is simple and convenient, it can be easily manufactured and the reliability thereof can be remarkably improved.

摘要： A magnetic core employed in AC motors, transformers and the like includes a first core portion formed by laminating silicon steel sheets each containing 3.5% silicon, the first core portion having two ends in the direction that the sheets are laminated, and second core portions disposed at the respective ends of the first core portion and formed by laminating silicon steel sheets each containing 6.5% silicon. In distorted wave alternating field, low frequency fluxes pass through the first core portion and harmonic fluxes pass through the second core portions. Since each second core portion has a low level of magnetostriction, the magnetic noise due to the harmonics is reduced.

摘要： A slotless motor has a sufficiently small gap between a stator and a rotor, and improves characteristics of the torque and the power factor. Accordingly, the slotless motor comprises stator cores having no slots, coils forming revolving magnetic fields in the stator cores, and rotors having a permanent magnet. The coils are disposed along the stator cores cylindrically and constructed in one layer. Each of the coils forms a part which decreases the distribution of the number of turns in the direction of a diameter of the stator cores, and adjoining coils pile on each other at the part in the direction of the diameter of the stator cores. The distribution changes in response to a predetermined range.

摘要： According to one embodiment, a rotor is configured by a rotor core and magnetic poles. Two or more types of permanent magnets are used such that each product of coercivity and thickness in the magnetization direction becomes different. A stator is located outside the rotor with air gap therebetween and configured by an armature core winding. At least one permanent magnet is magnetized by a magnetic field by a current of the armature winding to change a magnetic flux content thereof irreversibly. A short circuited coil is provided to surround a magnetic path portion of the other permanent magnet excluding the magnet changed irreversibly and a portion adjacent to the other permanent magnet where the magnetic flux leaks. A short-circuit current is generated in the short circuited coil by the magnetic flux generated by conducting a magnetization current to the winding. A magnetic field is generated by the short-circuit current.
