Abstract
A three-phase alternator having a fan wheel (23) mounted with ball bearing (17) on the rotor shaft (18,21). The fan wheel, which is free to rotate about the rotor shaft, is coupled to it by a coupling between the V-belt pulley (22) and the fan wheel, which employs a few spaced ball bearings (24,25,26;27,28,29) and support a spring washer (32,36,39,40) which presses against outer races of the bearings and the fan wheel.
