Hi Guys,
Can someone please explain to me the logic behind the representation of 'Magnetic Hysteresis loss' as a resistance in electrical equivalent circuits?... will be extremely grateful.
I have studied some info on this subject on the net. Even though the physics of Hysteresis Loss has been explained appropriately, I wish to dwell deeper into the phenomenon to get to the source of my doubt. In spite of the relevant theories, it becomes difficult to visualize a magnetic phenomenon into an electrical parameter as mentioned by me earlier. When we talk of energy expended by the power source to ‘pump up’ the magnetic field in the core, sounds a bit abstract!
I want to understand what phenomenon in the magnetic hysteresis causes the machine (Xmer or motor) to suck an additional losses (wattful) current from the power source.
Is it a result of the delay caused by the magnetic dipole friction in the magnetic core... which prevents the magnetic field from building up quickly? I would be grateful if someone could elaborate on this part. Thanx.
Kind Regards,
Shahvir
