Why are rotor core losses fixed?
Its not only about rotor, Core losses of every machine which has core are fixed and only vary with Voltage variation.
How do you reduce core losses in distribution transformer?
Reducing core losses is a design responsibility of the manufacturer. They do this by laminating the core (to reduce eddy-current losses) and carefully selecting the type of material used for the core (to reduce hysteresis losses). There's very little that you, as the user, can do about reducing core losses.
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Does a laminated iron core increase eddy current losses?
No, the purpose of laminating the core is to reduceeddy-current losses.
What is iron loss?
Iron losses (Pi) are independent of of load which occur due to pulsation of flux in the core. Iron losses include both Hysteresis loss and eddy current loss and is same at all the loads.
Why are rotor core losses fixed?
Its not only about rotor, Core losses of every machine which has core are fixed and only vary with Voltage variation.
Why core losses are always fixed in transformer?
Core losses are losses in the magnetic system of the transformer, such as eddy currents in the core, hysteresis losses, etc. Because of this, the losses are constant, regardless of load, assuming voltage and frequency stay fixed.
Why should we separate the core losses?
separation of core losses are necessary to determine core losses at diffrent frequency.........
How many types of losses in transformer?
Basically two types: 1. Copper losses:- when the transformer is loaded, current flows in primary and secondary winding, there is loss of electrical energy due to the resistance of the primary winding, and secondary winding and they are called variable losses. These losses depend upon the loading conditions of the transformers. Therefore, these losses are also called as variable losses. 2. Iron losses or core losses:-The losses that occur in the core are known as core losses or iron losses. Two types of iron losses are: > eddy current loss > Hysteresis loss.
How do you reduce core losses?
There are various measures that can be taken to reduce core losses. Lamination of the transformer core is believed to reduce core losses significantly.
How do you reduce core losses in distribution transformer?

There's very little that you, as the user, can do about reducing core losses.
How is the core losses occur?
The core loses occur because of the stator and rortor.
What are losses of transformer?
Core loss is one of the many fixed losses in a transformer. This means that no matter the loading of the transformer there this loss would be fixed unlike copper loss which depends on the loading of the transformer.
Why core losses are negligible in short circuit test of transformer?
I am so sorry for your core losses
What are core losses?
Iron losses are termed as core losses. There are mainly two losses - Copper loss and iron loss. Iron loss is no load loss.
Core loss of an induction motor?
Just like a transformer, the core losses are a combination of eddy current losses and hysteresis losses.
Is no heat loss and no core loss the same thing?
No. Core losses would be hysterisis loss and eddy current losses. Heat losses most likely is referring to I2R (I squared R) losses, which is losses due to the resistance of windings, and is dependent upon loading. There are other losses that are not heat related and core related - such as losses due to vibrations (the core is a major player here, but part of the noise is from windings and cooling systems). I've never heard someone refer to losses as "no heat" or "no core". These are fundamentally impossible - there WILL be core losses, and there WILL be I2R losses if you have a transformer and it is loaded.
