The days of a simple dc-charging subsystem in a car consisting of an alternator, rectifying diodes, basic regulator, and battery are nearly gone—no question of that. Now, the 12-V automotive regulator ...

The word “ideal” is often used in introductory engineering classes as a starting point to describe a component. However, at some point in any actual project or design, reality sets in, as there’s no ...

Safety is critical in automotive design. Cars aren't cheap, so it's necessary to protect the investment of the vehicle's owner. Most important, people's lives are at stake. That's why modern ...

Editor's note: The modern alternator is a very sophisticated piece of equipment which has virtually replaced the generator because of its lighter weight, higher efficiency, longer life and lower ...

A common problem exists when driving automotive alternators via motors. In the process of attempting to regulate the charging voltage of a low battery, the alternator shaft torque usually exceeds the ...
