File dati M6 di OPT

[mrttg]

Ciao Ivo,

Questo è il contenuto del tuo file relativo al metariale M6X:

; Core data for M6x

[GENERAL]
; Max allowed induction (in Tesla)
MaxB=1.4
[PERM]
; B=MU
;0=2000
0=300
0.05=8000
0.2=20000
0.8=26000
1.5=4000
1.8=1900
2=500
2.2=1


;S = "2000,0,8000,.05,20000,.2,26000,.8,4000,1.5,1900,1.8,500,2" 'From Sample1

Nel programma preumo che tù usi i dati sopra e non quelli dopo la variabile S?

Grazie e ciao

Hi Tiziano,

All lines starting with a ";" are comments.

MaxB in [GENERAL] just to ring the bell and to show in red.

In [PERM], all values are permeability according to induction.
Permeability is "absolute", I mean, already scaled by 1,26 (4 x pi /10).

Have fun !

Ivo.

Ma quindi siamo ad un mu di 26.000/1.26 a 0.8T ??

edcore per il suo lamierino dà questi dati:

Hi Piergiorgio,

Since I was unable to obtain coherent data about permeability, the table I used is the result of measured test bobins on various iron size, but all were M6X and from the same manufacturer.

The method was to feed the bobin with a variac and plotting current versus voltage.
From there one obtain the primary inductance at various induction levels and finally the absolute permeability may be computed.

I've found more convenient to express µ vs induction.

Ivo.
