摘要： Disclosed are a multilayered wound coil, a stator, and a manufacturing method therefor. The stator is provided with: a stator core comprising laminated steel sheets; and a coil which is wound around a teeth section formed on the stator core and has a plurality of layers formed in the circumferential direction of the stator core. The winding of the coil proceeds in either the radial direction or the circumferential direction of the stator core, whichever direction has fewer adjacent conductors, and doubles back at the end in said direction. This reduces the difference in potential between adjacent conductors, making it possible to ensure insulation between adjacent conductors even with a thinner insulating film.

摘要： A method of manufacturing a permanent magnet to be inserted in a slot of a motor rotor is achieved by including fracturing a rectangular parallelepiped permanent magnet block into two or more separate permanent magnet pieces having fractured surfaces, and assembling the two or more separate permanent magnet pieces so that fractured surfaces of two or more separate permanent magnet pieces are located in an outer peripheral surface of the permanent magnet. With the fractured surfaces of the separate permanent magnet pieces located in the outer peripheral surface of the permanent magnet, cut surfaces of the separate permanent magnet pieces are placed as contact surfaces of the separate permanent magnet pieces.

摘要： In a method for manufacturing a rotor, a plurality of cut magnet pieces (31, 32) are assembled in a rotor core (10) with both cut surfaces (31a, 32a) of the cut magnet pieces (31),(32) in a engaged state. The production method for the rotor includes a cutting step and a surface treating step. In the cutting step, a magnetic substrate (30A) having a recess (30a) formed in a surface thereof is cut using the recess (30a) as a starting point, thereby forming a first magnet piece (31) and a second magnet piece (32). In the surface treating step, cut surfaces (31a) are surface treated, so as to reduce protrusions (TO) on the cut surfaces (3 1 a) of the first magnet piece (31). Accordingly, the engagement between the cut surfaces (31a, 32a) is poor, the contact area is reduced, and the contact resistance is increased. As a result thereof, the eddy currents in the cut magnets (30) flow less easily, and a loss resulting from the eddy currents may be decreased.
