Glossary “field winding” Definition:
Term used for field coil.
What is field?
field relay
Glossary “field relay” Definition:
Relay that connects the alternator to the battery when alternator voltage is greater than battery voltage and disconnects it when battery voltage is greater than alternator voltage.
field terminal
Glossary “field terminal” Definition:
Electrical terminal connecting the field coil to the voltage regulator.
field frame assembly
Glossary “field frame assembly” Definition:
The round, soft iron frame of a generator or motor into which the field coils are assembled.
field coil
Glossary “field coil” Definition:
The coil, or winding, around the field magnets or pole pieces of a motor or generator. Also known as field winding.
field
Glossary “field” Definition:
1). Generally, any area being affected by some physical force. 2). Electrical force in the space around electrically charged particles. 3). Lines of force in a natural or man-made magnet between its north and south poles.
field density
Glossary “field density” Definition:
The density of the magnetic field, measured in the number of lines of force per unit area, dependent upon the strength of the field element, the number of turns of wire, and the size and characteristics of the pole piece.
Field Effect Transistor
Glossary “Field Effect Transistor” Definition:
A unipolar transistor in which current flow is controlled by voltage in a capacitance field
field effect transistor (FET)
Glossary “field effect transistor (FET)” Definition:
3-terminal semiconductor device where current flows from source to drain due to a conducting channel formed by a voltage field between the gate and the source.
