Wound strip machine
An electric machine. The electric machine includes one or more face wound strips including a first strip. The one or more strips have a plurality of openings. The first strip has a plurality of turns, and an opening of a turn of the first strip overlaps an opening of an adjacent turn, to form a portion of a fluid channel of a plurality of fluid channels. The turn and the adjacent turn abut against each other at the overlapping openings.
COMMON MODE FILTER
A multilayer common mode filter includes: a body including a coil part having a plurality of spiral coils, wherein the coil part has one lead portion connected to one of external electrodes disposed on the body and one or more dummy lead portions each connected to the other external electrodes, and the lead portion is connected to dummy lead portions of other coil layers stacked in a thickness direction in series. Therefore, even though the common mode filter is miniaturized, the common mode filter may secure predetermined levels or more of performance and reliability.
IRON CORE FOR STATIONARY INDUCTION APPARATUS AND STATIONARY INDUCTION APPARATUS
An iron core (1, 11, 31) for a stationary induction apparatus according to one embodiment is configured by laminating a plurality of electromagnetic steel plates (5, 16, 33). The electromagnetic steel plates are laminated so that joint parts (6, 17, 18, 32), at which the end portions of the electromagnetic steel plates abut one another, are disposed in a staggered manner; and the electromagnetic steel plates are provided with a magnetic domain fine differentiation processed part (7, 19, 34), which is located on the portion, of a surface of the end portion of each of the electromagnetic steel plates, lapped with the joint part of another electromagnetic steel plate, and which has been subjected to warping-derived magnetic domain fine differentiation.

ADHESIVELY-LAMINATED CORE FOR STATOR, METHOD OF MANUFACTURING SAME, AND ELECTRIC MOTOR
An adhesively-laminated core for a stator capable of suppressing an iron loss of an electric motor and also having excellent productivity is provided. The adhesively-laminated core for a stator includes a plurality of electrical steel sheets which are stacked on one another and of which both surfaces are coated with insulation coatings, and adhesion parts which are disposed between the electrical steel sheets adjacent to each other in a stacking direction and cause the electrical steel sheets to be adhered to each other. All sets of the electrical steel sheets adjacent to each other in the stacking direction are adhered via the adhesion parts. An adhesive forming the adhesion parts is a two-agent type acrylic-based adhesive (SGA) which includes an acrylic-based compound, an oxidizer, and a reducer and in which a portion of the acrylic-based compound and the oxidizer are assigned to a first agent and the remaining portion of the acrylic-based compound and the reducer are assigned to a second agent. The adhesion parts are partially provided between the electrical steel sheets adjacent to each other in the stacking direction.
