What else can I help you with?
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
Does a laminated iron core increase eddy current losses?
No, the purpose of laminating the core is to reduceeddy-current losses.
How is eddy current related to the thickness of the stampings of core?
A: Eddy currents are current losses if an iron bolt is used to hold the core lamination together that alone will cause losses. Usually a brass bolt is used to eliminate losses
What is eddi current?
An 'eddy' (not 'eddi'!) current is a current that flows in the magnetic circuit (core) of an electrical machine, due to a voltage induced into that core by a changing magnetic field. Eddy currents cause energy losses in electrical machines. To minimise eddy currents and, therefore, their losses, machines use laminated cores which restrict the paths through which eddy currents can flow.
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.

What are the advantages of shell type transformers?
this type of transformer used special low loss steel to minimize eddy current losses and reduced leakage flux.

Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
What are the different kinds of losses in machines?
stray losses,armature copper losses,iron losses(Hysteresis and eddy current losses),mechanical losses(friction and windage losses)
Is loss in ac current?
Yes, loss in alternating current (AC) can occur due to several factors, including resistive losses in conductors (known as I²R losses), which result from the flow of current through resistance. Additionally, losses can happen in transformers and other inductive components due to hysteresis and eddy currents. These losses can lead to reduced efficiency in AC systems compared to direct current (DC) systems. Overall, managing these losses is crucial for optimizing the performance of AC electrical systems.
On what factors does the eddy current loss depend?
Eddy current loss depends primarily on the material's electrical conductivity, the frequency of the alternating current, and the thickness of the conductive material. Higher conductivity and frequency increase the eddy currents generated, leading to greater energy losses. Additionally, thicker materials result in larger eddy currents, further amplifying the losses. The loss can be minimized by using laminated cores or materials with lower conductivity.
What are the Advantages of amorphous core for a transformer?
The following advantages are there: 1. Low hysteresis losses 2. Low eddy current losses 3. Skin-effect in core is low
