Abstract of the Disclosure A rotor for coreless motor comprises a cylindrical coil of wire wound and repetitively folded back to alternately change the current flowing direction with respect to the magnetic field of an associated stator of the motor and an inner conductor of the wire is exposed at a plurality of portions equally spaced in the folded back parts forming an axial endwise edge of the cylindrical shape of the coil. The conductor exposing portions correspond in number to motor poles and thus commutator segments, the latter of which are disposed adjacent and around an end of the rotor shaft and connected respectively at a radially extended end substantially directly to the coil conductors at each of its exposed portions.
