Definition

1. Noun:
   • A specialized electrical coil: A "field winding" is the insulated wire coil wound around the field magnet (the stationary part) in an electric motor or generator.
   • Function in an electric machine: Its primary purpose is to carry electric current to produce the magnetic field (magnetomotive force) necessary for the machine's operation. This magnetic field is essential for generating torque in a motor or voltage in a generator.

Usage Examples

• Noun:
  • The technician carefully inspected the field winding for any signs of insulation damage.
  • In a DC generator, the field winding is connected to a direct current source to create a steady magnetic flux.

Advanced Usage

• "To energize the field winding": To supply electrical power to the field winding to create its magnetic field.
  • Before starting the large motor, engineers must first energize the field winding.

Variants and Related Words

• Field coil: A direct synonym for "field winding."
• Exciter winding: A specific type of field winding used to provide initial excitation in some generators.
• Armature winding: The other main winding in an electric machine, which is the rotating part that carries the load current, in contrast to the stationary field winding.

Synonyms

• Field coil: The most common and direct synonym.
• Exciter: In specific contexts, particularly for generators.

Related Technical Phrases

• Shunt field winding: A field winding connected in parallel (shunt) with the armature circuit.
• Series field winding: A field winding connected in series with the armature circuit.
• Separately excited field: A configuration where the field winding receives power from a source independent of the machine's main power circuit.

Noun

1. the electric coil around a field magnet that produces the magneto motive force to set up the flux in an electric machine
