Rotor of an Alternator

The present invention relates to a rotor for an alternator, including a first claw pole element and an opposite second claw pole element and a plurality of N-pole claw-shaped bodies of the first claw pole element and a plurality of S-pole claw-shaped bodies of the second claw pole element being respectively adjacent to each other and spaced apart; wherein a permanent magnet is fixed between each of the N-pole claw-shaped bodies of the first claw pole element and each of the S-pole claw-shaped bodies of the second claw pole element which are adjacent to each other, to increase a magnetic field generated after the rotor is electromagnetically conducted and decrease magnetic leakage between the two pole elements, thereby increasing generating capacity of the alternator.
