MARELLI AA 125 R, 14V / 45A PERFORMANCE CURVE
The attached performance curve was plotted at a constant system
voltage
voltage of 13.5V and at an ambient temperature of 25°C.
P1 = Power Output (KW)
I = Current Output (Amps)
n= Efficiency
NOTES:
1. The RPM shown is that of the alternator. The value of the rpm axis
must be multiplied by 1000.
2. Alternator speed is a function of engine speed and the crankshaft
pulley diameter. If the engine pulley is 88 mm, then the alternator
speed ration is 1.3:1. If the engine pulley is 108 mm, then the
alternator speed ratio is 1.6 : 1.
