The magnetizing resistance is the Rm and is used to model the no-load losses in the classic equivalent circuit of the transformer. To calculate you need to know the no-load losses and the voltage of the primary (there is a detail on which side to position the magnetizing branch, in your figure, it is in the primary winding, numbered as 1).

The Magnetizing inductance / reactance can be referred to either the primary or the secondary of the transformer. For example, if you use the open circuit test as described above, you would include it in the primary of your model. You can then use the turns ratio to refer it to the secondary.
5 gru 2017 · So, measuring primary impedance for wide range of frequencies is the best practice to estimate the magnetizing inductance. Procedure: First, you need to know the frequency that the transformer is designed for (\$f_{tr}\$).
18 paź 2014 · The magnetizing reactance is defined as the result of calculating the electric machine magnetic circuit. In this chapter, the magnetic circuit is calculated by the use of an electric equivalent circuit, the elements of which represent the magnetizing reactance values of magnetic circuit regions.
10 gru 2016 · \(R_1\) and \(X_1\) represents the resistance and reactance in the primary winding, while \(R_2\) and \(X_2\) represents the secondary winding. \(X_m\) and \(R_m\) represents the magnetizing reactance, and core losses respectively.
VT = the primary voltage Ife = core-loss component. I0 = exciting current IM = magnetizing component. Rfe = resistance that represents the core losses Xm = inductive reactance that represents the core magnetizing L. Example 8-3: Computing the values of magnetizing reactance and core loss resistance.
Mutual inductance (magnetizing inductance) rep-resents energy stored in the finite permeability of the magnetic core and in small gaps where the core halves come together. In the equivalent cir-cuit, mutual inductance appears in parallel with the windings.
