Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
Causes of hysteresis loss in transformer?
No, you're hysteresis losses are set by Bmax, frequency, and material. The function is highly nonlinear and the loss goes up disproportionately with Bmax. When designing power transformers, you typically want the hysteresis + eddy losses to equal the copper losses.
What is AD current loss?
AD current loss could refer to a comic, called Eddy Current. It could also refer to AD loss, memory loss caused by Alzheimer's Disease.
What are losses of transformer?
Core loss is one of the many fixed losses in a transformer. This means that no matter the loading of the transformer there this loss would be fixed unlike copper loss which depends on the loading of the transformer.
How do you reduce the hysteresis loss?
Hysteresis losses are a function of the magnetic characteristics of the magnetic circuit, so there is very little you can do to minimise hysteresis losses other than to reduce the primary voltage to a transformer if that is at all practicable. These losses are really in the hands of the manufacturers who design and manufacture magnetic circuits.

How do you minimize core losses?
Hysteresis and eddy current loss constitute core loss. It can be reduced by replacing solid core by laminated core... by adeeb
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Why core loss depends on voltage?
Core loss depends on voltage because it is primarily due to hysteresis and eddy current losses in the magnetic core material. When the voltage increases, it leads to higher magnetic flux density variations within the core material, causing an increase in hysteresis and eddy current losses, thus resulting in higher core losses.
What is magnetic loss in the stator called?
Magnetic loss in the stator is commonly referred to as "core loss" or "iron loss." This loss occurs due to the alternating magnetic field in the stator, which leads to energy dissipation primarily through hysteresis and eddy currents in the magnetic core material. Hysteresis loss is related to the magnetic properties of the material, while eddy current loss is caused by circulating currents induced in the core. Together, these losses reduce the overall efficiency of electromagnetic devices like motors and transformers.
What are the different factors on which hysteris loss and eddy current loss depends?
Hysteresis loss depends primarily on the magnetic properties of the material, such as its permeability and the frequency of the magnetic field, as well as the area of the hysteresis loop, which reflects energy loss during magnetization and demagnetization cycles. Eddy current loss, on the other hand, is influenced by the material's electrical conductivity, the thickness of the material, and the frequency of the alternating magnetic field; higher conductivity and thickness lead to increased eddy currents and associated losses. Both losses increase with higher frequencies, making material selection and design critical in minimizing these energy losses in electromagnetic applications.

Power loss in open circuit test?
There is no power loss in open circuit test. Actually there is iron loss also known as magnetic losses. These include hysteresis and eddy-current losses. This can be described as V1^2/Rc Where V1 is the primary voltage and Rc is the resistance of the magnetic core.
What is iron loss?
Iron losses (Pi) are independent of of load which occur due to pulsation of flux in the core. Iron losses include both Hysteresis loss and eddy current loss and is same at all the loads.
What is difference between eddy current loss and hysterisis loss?
Whenever rotor cuts the magnetic field, emf is induced it. Due to this emf, some current may flow in the rotor. This current is called Eddy current which is unnecessary and considered a loss called Eddy current loss. When a magnetic material is energised it follows B-H curve and when de-energised, it does not follow B-H curve. This difference is considered a loss called Hysterisis loss.
