Abstract

The utility model discloses an electric rotating machinery which comprises a stator and a rotor. The annular rotor is arranged in the center of the stator, a permanent magnet is arranged on the outer ring of the rotor, and a gap is arranged between the permanent magnet and the stator. The stator comprises an annular yoke iron core, a teeth portion iron core is arranged on the inner ring of the yoke iron core, adjacent teeth of the teeth portion iron core form connection through a connection portion. And a stator coil is arranged on each tooth of the yoke iron core. The electric rotating machinery is of an electrostatic screening structure, can reduce shaft voltage and is simple in structure and fewer in manufacture process.
