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.

Why armature core is laminated in dc machine?
to reduce the eddy current loss in the machine
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
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 the Technical meaning of CRGO Lamination?
To minimize hysteresis loss
What is hysteresis loss?
If the magnetic field applied to a magnetic material is increased and then decreased back to its original value, the magnetic field inside the material does not return to its original value. The internal field 'lags' behind the external field. This behaviour results in a loss of energy, called the hysteresis loss, when a sample is repeatedly magnetized and demagnetized. The materials used in transformer cores and electromagnets are chosen to have a low hysteresis loss. Similar behaviour is seen in some materials when varying electric fields are applied (electric hysteresis). Elastic hysteresis occurs when a varying force repeatedly deforms an elastic material. The deformation produced does not completely disappear when the force is removed, and this results in energy loss on repeated deformations.

Does a diamagnetic substance exhibit hysteresis loss?
No, diamagnetic materials do not exhibit hysteresis loss because they do not have permanent magnetic moments that can be aligned and re-aligned in response to an external magnetic field. Hysteresis loss occurs in ferromagnetic materials due to the energy dissipated during the reversal of magnetic domains.

To minimize hysteresis loss
How can hysteresis loss in magnetic material may be reduced?
Hysteresis losses depend on the type of metal used to manufacture the magnetic circuit of a machine. Most magnetic circuits are made from silicon steel. Generally speaking, there's not much you can do to reduce hysteresis losses as that has already been factored in by the machine's designer.
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.
Why core is made up of silicon steel?
produces magnetic properties,such as small hysteresis area and permeability Hysteresis loss depends upon the material of the core
How do you calculate the Hysteresis loss given a B-H curve?
hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density
Is hysteresis loss considered heat loss?
In general even though energy is lost during hysteresis it is not called as heat losses . Generally I2R losses are called as heat losses because in these tye of only in these energy is lost in the form of real heat
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
