What does hysteresis mean in magnetism?
Lagging intensity of magnetization with respect to magnetizing field is called hysteresis.
Is hysteresis desirable in a transducer why?
Not usually. In most applications you want a linear response in voltage to stimulus with as low a time constant for change as possible. This is the ideal and not completely achievable or justified by the cost. As a rule the smaller the stimulus being measured the less desirable hysteresis. Think of an elephant sitting on the scale it takes some moments for the springs and counter weights to reach an equilibrium. A funny thing…

Causes of hysteresis loss in transformer?
Changes in the magnetic field will always produce hysteresis loss. Since transformer works based on the electromagnetic induction. Hysteresis loss is predominant. It can be minimized by stampings with suitable design.

Why hysteresis is necessary?
Without hysteresis, computers would have no memory (either short term or long term), and even if I were fast enough to type this message completely before my computer forgot about it, there would be no way for you to read it without a storage disk, which basically works of some sort of hysteresis (most probably ferromagnetic) hysteresis is «a dependence on the past»: it’s memory.
What is hysteresis?
Hysteresis is an output’s dependence on both current and historical input. This is necessary because the current state is affected by historical inputs.
What are the applications of multilevel inverters?
The various applications of multilevel inverters are 1. Motor Drives 2.Active Filters 3.Power conditioning
How do you calculate the Hysteresis loss given a B-H curve?
By find out the area of the B-H curve we can calculate the hysteresis loss.
Why magnitism lags behind magnetisg current in hysteresis?
Because that’s the very definition of hysteresis. The reason there is hysteresis is because some energy is required to change the magnetization of many materials — you can compare this to a type of friction, though the details vary from the usual friction.
What type of machine that use asynchronous motor?
Typically a synchronous motor is applied in constant speed applications where the higher cost of the motor is offset by the improved power factor realized
What are the applications of encoder?
In terms of motor drives an encoder will be attached or integral to the motor shaft. As an example it may typically have 1000 «segments» so 1000th of a revolution resolution, particularly in DC drive technology and braked motor applications, it is used for precise positioning usually via its own control equipment to a PLC.
How reduce the hysteresis loss in a 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.

How do you reduce hysteresis losses?
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.
How hysteresis comparator works?
Comparator is usually a substance which compares two quantities; one quantity is the processed one and the other is a standard value to which the processed value has to be compared. Hysteresis is a property in which the change in the magnetization lags behind change in the magnetic field. Now, Hysteresis comparator can be described as a comparator which compares a processed quantity with a quantity whose value is standard for hysteresis property., the difference…

How do you reduse hysteresis loss in the transformer?
hysteresis loss is minimised by using a core of a soft magnetic material which magnetises and demagnetises easily e.g soft iron
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 minimize 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.
Ford motor company employment application or resume fax or address?
Yes they has applications.
What is the hysteresis losses?
Hysteresis is the dependence of a system not only on its current environment but also on its past environment. This dependence arises because the system can be in more than one internal state. To predict its future development, either its internal state or Tratament Par Alb its history must be known.[1] If a given input alternately increases and decreases, the output tends to form a loop as in the figure. However, loops may also occur because of a…
Can you run 460 volt 60 Hz motors in a 460 volt 50 Hz system?
Yes but they might run slower. A synchronous motor would definitely run at 5/6 of the speed. Also the motor might heat up because of increased power loss in the iron core due to hysteresis.
What is the importance of speed control of DC motor in industrial applications?
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
What are the applications of wireless control of a dc motor?
Overhead cranes and ‘Yard’ locomotives to name a few.
What are the applications of electromagnet?
alarm mechanism. door mechanism. switches. controller. motor rotor . . etc
Formula of Hysteresis loss and Eddy current loss?
hysteresis loss = N1/N2 R2/R1 C1/A1 (area of the loop)(vertical sensitivity) (horizontal sensitiivity
Where does hysteresis in a transformer depend on?
The power lost by hysteresis depends on the peak flux density in the core. If the transformer is getting hot even when on no load, it should be run at a lower voltage.
What is a hysteresis loop?
The hysteresis loop for a stress — strain graph represents the energy per unit volume (energy density) that is transferred to internal energy during the loading and unloading cycle.
