An electrical generator which has both a series and a shunt field winding.
Industry:Aviation
An electrical generator which has both a series and a shunt field with the effect of the series field being greater than that of the shunt field. The output voltage tends to increase as the electrical load increases.
Industry:Aviation
An electrical generator whose field coils are supplied with current produced in the armature. The voltage regulator for a self-excited generator is a variable resistor in the field circuit between the armature and the field coils or between the field coils and ground. When the resistance in the field circuit decreases, the field current increases, and the generator output voltage increases. Most aircraft generators are self-excited, but DC alternators are not.
Industry:Aviation
An electrical generator whose field windings are connected in shunt (parallel) with the armature winding. Most aircraft generators are shunt-wound, because their output voltage can be controlled by varying the amount of current flowing through the shunt-connected field winding.
Industry:Aviation
An electrical heater embedded in the die used for hot dimpling sheet metal.
Industry:Aviation
An electrical heater used to heat liquids by immersing (submerging) the heater in the liquid.
Industry:Aviation
An electrical inductor wound around a ring-shaped core made of a highly permeable material. The ring-shaped core concentrates the magnetic flux and allows a minimum amount of flux to be lost in an external field.
Industry:Aviation
An electrical instrument that measures the frequency of an alternating current and shows this frequency directly on its dial.
One commonly used type of frequency meter is a vibrating reed-type instrument. A series of metal reeds of different lengths is excited by the AC, and the reed that vibrates with the greatest amplitude is resonant at the frequency of the AC. The frequency at which each reed is resonant is marked beside each reed.
Industry:Aviation
An electrical instrument that measures the voltage of a source without taking current from it. The unknown voltage is compared with an adjustable voltage that can be accurately measured. When no current flows between the two voltage sources, they are exactly the same.
Industry:Aviation
An electrical instrument that measures voltage in units of millivolts (thousandths of a volt).
