Hysterisis losses are the losses which are taking place in the iron or steel core due
to reversal of magnetisation of steel core.
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 hysteresis losses
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
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.
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.
The area of the hysteresis loop in a ferromagnetic material represents the energy losses that occur during the magnetization and demagnetization processes. It is a measure of the energy dissipated as heat due to the magnetic domain reorientation within the material. The larger the area of the hysteresis loop, the greater the energy losses and the lower the efficiency of the material in applications such as transformers or inductors.
To minimize hysteresis loss
produces magnetic properties,such as small hysteresis area and permeability Hysteresis loss depends upon the material of the core
hysteresis loss= K B^1.6 egs/sec where k is STEINMEITZ coefficient and B is the maximum magnetic flux density
to reduce the eddy current loss in the machine
The Steinmetz equation is used to calculate iron losses in electrical machines like transformers and motors. It takes into account both hysteresis and eddy current losses. The equation is given as P_loss = KfB_max^1.6*V^2.2, where P_loss is the iron loss, K is a constant, f is the frequency, B_max is the maximum magnetic flux density, and V is the volume of the iron core.
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
