Winding
Purpose
Ideal winding defining an electro-magnetic interface

Magnetic
Description
The Winding forms the interface between the electrical and the magnetic domain. A winding of N turns is described with the equations:
where and
are voltage and current at its electrical terminals.
is the
magneto-motive force (MMF) and
is the rate-of-change of the magnetic flux
through the winding. The left-hand side of the equations above refers to the electrical
domain, the right-hand side to the magnetic domain.
A current entering the winding at the marked terminal is counted as positive; a magnetic flux entering at the marked terminal is counted as negative. The potentials of both voltage and MMF are considered positive at the marked terminal.
Because the Winding converts through-quantities ( resp.
) in one domain
into across-quantities (
resp.
) in the other domain, it is implemented as a
gyrator, in which
is the gyrator resistance.
Parameters
- Number of turns
- Specifies the number of winding turns.
Probe Signals
- Winding voltage
- The voltage measured from the positive (marked) to the negative electrical terminal of the winding, in volts (V).
- Winding current
- The current flowing through the winding, in amperes (A). A current entering the winding at the marked terminal is counted as positive.
- MMF
- The magneto-motive force measured from the marked to the unmarked magnetic terminal, in ampere-turns (A).
