PROBLEM TO BE SOLVED: To provide a three-phase permanent magnet type alternator capable of improving power generation characteristics by fining the wires of a stator coil 9 while the stator coil 9 isΔ-connected. SOLUTION: The three-phase stator coil 9 havingΔconnection groups I, II connected in parallel is formed in such a way that, of three-phase coils, U-phase coils are wound in parallel while being separated into coils U1, U2, U3 and coils U4, U5, U6, V-phase coils and W-phase coils are wound in the same way with every one slot shifted, and the coils U1-U3, V1-V3 and W1-W3 are subjected toΔconnection to form the firstΔconnection group I, the coils U4-U6, V4-V6 and W4-W6 are subjected toΔconnection to form the secondΔconnection group II; and corresponding connection portions of theΔconnection groups I, II are each connected to the resulted body having the first and secondΔconnection groups by wirings 10, 11, 12.
