Purpose

Ideal winding defining an electro-magnetic interface

Description

pict

The Winding forms the interface between the electrical and the magnetic domain. A winding of N turns is described with the equations:

v = N P

   F-
i = N

where v   and i   are voltage and current at its electrical terminals. F   is the magneto-motive force (MMF) and P   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 (P   resp. i  ) in one domain into across-quantities (v   resp. F  ) in the other domain, it is implemented as a gyrator, in which N   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).
