PURPOSE:To increase the coil coefficient of a superconductive rotary electric machine by increasing the length of the part, on which a 180 deg. skew air gap armature coil is wound obliquely to the axial direction longer than the length of a stator core in the axial direction. CONSTITUTION:A 180 deg. skew air gap armature coil 3a is formed in the length la of the part, on which the coil is wound obliquely to the axial direction longer than the axial length li of a stator core 2. Thus, the effective sectional area crossing a magnetic flux is increased, thereby obtaining the 180 deg. skew air gap armature coil 3a of the coil coefficient. In this manner, since the number of coils of upper and lower layer coils 4c, 4d may be reduced, and the size Walpha of the coil interval is increased, the efficiency of the electric work such as connecting work or the like can be improved. |
