PROBLEM TO BE SOLVED: To effectively reduce the temperature rise of a rotor, resulting from high frequency magnetic flux by the simplified manufacturing processes. SOLUTION: A rotary electric machine comprises a magnetic pole 12, a lump form rotor iron core 11, having a coil inserting slot 13 to the part other than the magnetic pole 12 and teeth 14 formed between the slots and a field coil 15 inserted to the slot 13. In this case, a slit 31 is provided to the surface of the magnetic pole end part on the side, where the absolute value of the magnetic flux density becomes high due to the repulsive effect of the armature, and electrical resistance is increased to effectively reduce temperature rise. |
