Model of transformer
Ideal Transformer
- Zero windings resistance.
- Infinite permeability.
- No flux leakage.
- No core losses.
H is referring to magnetic field strength. B is referring to flux density.
The flux in the core of the transformer is net of which is set equal to zero in an ideal transformer but set equal to the reluctance of propagation of the flux in the core.
Rotor circuit impedance is affected by speed.
Induction motor draws more current as you increase load? Same with transformer
