Abstract:
A vehicle A.C. generator has a rotor. The rotor has a pair of pole cores and magnet holders. Each pole core has a plurality of claw-like magnet poles. Each magnet holder contains a permanent magnet and placed between the adjacent claw-like magnet poles in order to prevent leakage flux. The rotor has a pair of supporting members in order to stop each magnet holder shifting in the direction of a rotary shaft of the rotor.
