Abstract

Disclosed is an alternator being used for producing electrical energy, the alternator comprising: an elongated shaft having first end and second end; an armature being placed.on the shaft and responsible for producing the energy, the armature comprising armature core and armature winding, the armature winding includes plurality of coils and conductors, the armature core is adapted to accommodate the coils and conductors of the armature winding; a plurality of field coils surrounding the armature and being placed on poles for setting up magnetic field, the poles are placed on a pole core; a commutator being placed at one end of the armature on the shaft, the commutator is adapted to facilitate collection of alternating current induced in the conductors of the armature winding and convert the alternating current into unidirectional current in a external load circuit; a pair of brushes being placed on the commutator for collecting current from the commutator; a first fan being placed on the shaft after commutator for cooling of the alternator; a first bearing being placed on the shaft after the first fan so that the first fan remains between the commutator and the first bearing; a second bearing being placed on the shaft at other end of the armature; a second fan being placed on the shaft after the second bearing and adapted to function as an exhaust fan; a third bearing being placed on the shaft after the second fan so that the second fan remains between the second bearing and third bearing; a first flywheel being placed at the first end of the shaft such that the third bearing remains between the second fan and the first flywheel; and a second flywheel being placed at the second end of the shaft such that the first bearing remains between the first fan and the second flywheel.
