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.

∙ 12y agoHysteresis losses are a function of the area of the B-H(flux density:magnetising force) loop for the material used in the manufacture of the core. The lower the area of the B-H loop, the lower the hysteresis losses. So what it comes down to is the choice of alloy used to construct the core -usually, variations of silicon steel.

∙ 12y agoThere are two losses occured in transformer one is eddy current loss & another is hysteresis loss. The iron core is magnetise & de-magnetise due to AC provide to primary winding,causes waste of heat called as hysteresis loss.we can't eleminate the loss but we can redue it to some extend by making a core of silicon steel that enables easy magnetisation.

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.

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.
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
Why Soft Iron is suitable for preparing electromagnets?
soft iron B-H curve area is very high and hysteresis loss is proportional to it frequency or no of loop cycles per sec and area of loop so hysteresis loss increases in soft iron as electro magnet
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
