Where is the alternator located in an aircraft?
The alternator is mounted in the engine compartment driven by a v-belt, or drive gear mechanism, which receives power from the aircraft engine. [Figure 1] The control system of a DC alternator is used to automatically regulate alternator output power and ensure the correct system voltage for various flight parameters. Figure 1.
What is the control system of a DC alternator?
[Figure 1] The control system of a DC alternator is used to automatically regulate alternator output power and ensure the correct system voltage for various flight parameters. Figure 1.
How is the field current lowered in an alternator?
As the points of the relay open, the field current is lowered and alternator output is lowered and vice versa. Solid-state regulators for modern light aircraft are often referred to as alternator control units (ACUs).
Which is more efficient a DC generator or a DC alternator?
In general, DC alternators are lighter and more efficient than DC generators. DC alternators and their related controls are found on modern, light, piston-engine aircraft. The alternator is mounted in the engine compartment driven by a v-belt, or drive gear mechanism, which receives power from the aircraft engine.

How to determine the minimum size of an alternator?
To determine the minimum size of alternator that you need for a typical automotive or marine application, use the two simple formulas/calculations shown below. The first formula calculates the minimum amount of CONTINUOUS DUTY output current that your alternator (or your charging system) needs to produce, at engine idle]

What makes an alternator a high power alternator?
This is the amount of power that the vehicle needs for its basic onboard equipment — engine ignition/controls, fuel pumps, instrumentation, lights, climate control systems, etc. This type of alternator is usually identified by the maximum amount of power that it can produce when the engine is operating at high speed.
