1.No-load test (inspect charging circuit without load)
In the no-load test, whether the generated voltage is maintained at a constant level (regulated voltage) is cheeked even if the alternator speed Read more Inspection in Charging System

SC Type Automotive Alternator
An SC type alternator adopts a joined segment conductor system (insert the segment conductor and weld it) to the stator winding method. This type of alternator can reduce the resistance value by half comparing Read more SC Type Automotive Alternator
Automotive Output Control by IC Regulator
The following explains the mechanism by which the IC regulator keeps the generated voltage constant and how it operates to achieve this function using a battery sensing type IC regulator as an example.
1.Normal Read more Automotive Output Control by IC Regulator
Regulate Generated Electricity
Self-control for maximum output current
A characteristic of the alternator is that the output current flows almost constant when it exceeds a certain speed (self-control operation).
Therefore, when Read more Regulate Generated Electricity
Alternator with Neutral-Point Voltage
Neutral-point voltage
(1)A conventional alternator uses six diodes to rectify three-phase AC (Alternating Current) into DC (Direct Current). The output voltages generated at the neutral point is utilized Read more Alternator with Neutral-Point Voltage
