PROBLEM TO BE SOLVED: To easily detect a rotation position of a rotor of an electric machine having a stator and a permanent magnet rotor and to easily constitute an armature core, armature coils, and a rotor structure of the electric machine. SOLUTION: In this electric machine, magnetic fields of magnets 270 of a rotor are detected, by at least one magnetic field detector 190 mounted on the end of a core 120 of a stator. The detector is fixed to a tooth 130 of the stator. Using such a constitution, it is not necessary to add a magnet for rotor position detection. Further, coil windings are formed with a bundle of insulated wires and nonmagnetic plates, are provided on the ends of the rotor. |
