PURPOSE:To reduce radio interference to communication lines or others by a synchronous machine and also enhance reliability of the machine by a method wherein conductor rods of a magnetic core are arranged in dislocation by a specific factor of a slot spacing of a stator core relatively in neighboring N and S poles. CONSTITUTION:P is assumed to be a distance between pole center lines 6 and 7 of neighboring N and S poles, respectively. A conductor rod spacing A and a stator core spacing B must be same, and in the N pole, conductor rods 2 are dislocated by B/4=delta from the N pole center line 6 to the left side on the whole and in the S pole, by the same amount delta from the S pole center line 7 to the right side, and following further in the same manner on all poles, rods are dis- located relatively in N and S poles in turn by half the slot spacing B of the stator iron core. With this structure, distortion of an induced voltage waveshape at a stator line-side terminal can be improved, and radio interference influenced on communication lines and others is reduced, and also reliability of the machine is enhanced. |
