Fundamental Reluctance
Magnetic resistance (simplified model).
Description
The Fundamental Reluctance block represents a simplified model of the magnetic resistance, i.e. the component that resists the magnetic flux. Unlike the Reluctance block, which calculates the resistance based on the geometry of the modelled section, the Fundamental Reluctance block allows you to specify the resistance value directly as a block parameter.
The block is based on the following equation:
,
where:
-
- is the magnetomotive force (MDF) on the component.
-
- flux through the component.
-
- magnetic resistance.
Connections N and S are magnetic ports. The MFM across the resistance is defined by the expression and the sign of magnetic flux is positive when flowing through the device from N to S.
Ports
N - north terminal
`magnetism
Magnetic port corresponding to the north terminal of the unit.
S is the south terminal
magnetism
Magnetic port corresponding to the south terminal of the unit.
Parameters
Reluctance, 1/H - magnetic resistance
80000 1/Hn (by default)
The ratio of the magnetomotive force (MDF) on a component to the resultant flux through the component.
Initial value of flux, Wb - initial value of flux
`0 (By default)
Initial value of flux.
Initial value of MMF, A - initial value of MMF
0 (By default).
Initial value of MMF.
