    • The invention relates to a rotor or stator for an electric machine, in particular a spoke rotor which is arranged concentrically about a rotational axis and comprises a permanent magnet which is arranged in a recess of the rotor or stator. A spring strand for fixing the permanent magnet in the recess is provided in the rotor or stator, said spring strand comprising a holding ring and fixing means which are arranged on the holding ring. Said holding ring is arranged concentric about the rotational axis, and the fixing means extend in the axial direction of the rotor or stator into the recess. The holding ring is annular and the fixing means lie at least partially directly on the permanent magnets. The invention also relates to an electric machine comprising the claimed rotor. The invention further relates to a hand-held machine comprising a motor having a rotor or stator of the above-mentioned type.

    • An electric rotating machine including inner and outer rotors coaxially disposed and driven by a compound current, and a stator disposed between the rotors. Each of the rotors includes a plurality of permanent magnets circumferentially arranged. The stator includes a stator core and a coil to which the compound current is applied. The stator core includes a plurality of circumferentially arranged stator pieces with the coils. The stator pieces have a same shape and are formed by plates laminated in axial alignment with each other. Each stator piece includes inner and outer yokes disposed radially inside and outside, respectively, and a coil area defined between the yokes. The stator pieces adjacent to one another include a first air gap circumferentially formed between the adjacent outer yokes, a second air gap circumferentially formed between the adjacent inner yokes and mutual contact portions circumferentially contacted at the inner yokes.
