ABSTRACT:
It is an object of this invention to provide a compact high-power alternator for a vehicle. An alternator (1) for a vehicle includes a stator (2) and a rotor (3). The stator (2) serves as an armature. The rotor (3) operates to generate magnetic field. A front cooling fan (12) and a rear cooling fan (13) are fixed to two axial-direction ends of the rotor (3) respectively. The outside diameter (R0) of the cooling fans (12, 13) is equal to the outside diameter (R1) of the rotor (3) which is multiplied by a value of 0.90 to 0.96. The stator (2) includes a stator iron core (32), a stator winding, and an insulator (34) for providing insulation between the stator iron core (32) and the stator winding. Coil end groups (31a, 31b) extend from axial-direction end surfaces of the stator iron core (32) respectively. In the coil end groups (31a, 31b), gaps are formed between portions of the stator winding. Here, 70% or more (for example, 80%) of inner circumferential surfaces of the coil end groups (31a, 31b) is opposed to the cooling fans (12, 13).
