There is provided a method for manufacturing a stator core for an axial air-gap electronic motor, in which core sheets are laminatedly fixed while being shifted with predetermined intervals. The method includes a step in which first side surfaces in the circumferential direction (first slot surfaces) of the first to nth (n is a positive integer) core sheets are blanked out of a mother sheetby moving first blanking puncheswith predetermined intervals via a first control means; and a second blanking step in which second side surfaces in the circumferential direction (second slot surfaces) of the first to nth (n is a positive integer) core sheets are blanked in succession by moving a second blanking punchwith predetermined intervals via a second control means

Method for manufacturing a stator core for an axial air-gap electronic motor

An axial gap electronic motor includes a stator and a rotor disposed opposingly with a predetermined gap. In order to provide an easy assembling operation of the stator, the stator includes a plurality of pole members annularly connectable. The annular stator core is obtained by connecting each of the pole members to which coil winding is previously applied.

Axial gap electronic motor

An axial gap electronic motor includes a stator having a plurality of poles, and a rotor. Each pole is formed of a stator iron core made of a magnet body and a coil wound therearound. The rotor has a plurality of poles formed of permanent magnet and arranged along a rotation axis direction of said rotor with a predetermined gap provided therebetween. The stator has a magnetic force generating section in which a plurality of the stator iron cores is arranged in a ring shape on a concentric circle with the rotation axis line of the rotor being a center axis. Each of teeth of the stator iron core is provided with a skew.
