Alternators Using Aluminium Wires In Stator Assemblies

Abstract: An alternator for use in a vehicle comprises a stator assembly, a rotor, a casing, a shaft, an external fan, a first internal fan, and a second internal fan. The stator assembly comprises a stator frame and a stator winding wound on the stator frame. The stator winding is made of aluminium. The rotor is enclosed inside the stator assembly and has a first end and a second end. The second end is opposite the first end. The casing encloses the rotor and the stator assembly. The shaft is disposed in the casing with ends thereof extending beyond the casing. The shaft is rotatable about a fixed axis and the shaft having the rotor fixedly disposed thereon. The external fan is mounted on the shaft and is disposed outside the casing. The first internal fan is mounted on the shaft and is disposed inside the casing at the first end of the rotor. The second internal fan is mounted on the shaft and is disposed inside the casing at the second end of the rotor.
