● PERFORMANCE CURVE OF ALTERNATOR
As shown in the performance curve below, the alterna-
tor does not generate the power until its speed reaches
1,200 rpm.
This minimum revolution speed is called "Cut In
Speed".
If the alternator's speed is below the cut in speed, the
alternator does not generate the power and the charge
warning lamp does not go off.
Also, the power performance changes as the output
current (A) changes according to the coil's temperature
(cold and hot). Therefore, the average curve for the
cold and hot conditions is presented as guaranteed
performance.
In general, the alternator's pulley ratio is determined to
maximize the alternator power in the rated speed of the
engine.
This engine's speed ratio between alternator pulley
to crank shaft pulley is 2.16.
Therefore,the alternator pulley speed will be over
1800rpm while the engine is idling.
However,for the fast charge of battery run the engine
at 1500rpm or faster.
* Maximum output ampere : 50A
