Air Gap
Purpose
Air gap in a magnetic core
Library
Magnetic
Description
This component models an air gap in a magnetic core. It establishes a linear
relationship between the magnetic flux
and the magneto-motive force

where
is the magnetic constant,
is the cross-sectional area
and
the length of the flux path.
Parameters
-
Cross-sectional area
- Effective cross-sectional area
of the air gap, in
.
-
Length of flux path
- Effective length
of the air gap, in m.
-
Initial MMF
- Magneto-motive force at simulation start, in ampere-turns (A).
Probe Signals
-
MMF
- The magneto-motive force measured from the marked to the unmarked
terminal, in ampere-turns (A).
-
Flux
- The magnetic flux flowing through the component, in webers (Wb). A flux
entering at the marked terminal is counted as positive.
-
Field strength
- The magnetic field strength
in the air gap, in A/m.
-
Flux density
- The magnetic flux density
in the air gap, in teslas (T).
