What is the function of magnetic core in electrical machine?
The core, together with the machine's air gaps, form what is known as a 'magnetic circuit', which is a low-reluctance path that encloses the magnetic flux produced by its field windings, in order to concentrate that flux in the air gap through which the armature passes.
What does AUK air gap stand for?
auk air gap
How can the leakage flux be minimized?
by bringing the primary and secondary windings as close to each other reducing the air gap. interwinding the primary and secondary.Additional AnswerAnother method is to use a wound core, rather than a stamped core.
Is there a code for a 1'' air gap in a tub spout installation?
Yes and an air gap for a basin faucet and an air gap located in most dishwasher and washing machines. The actual size of the air gap is 2 times the effective opening (supply pipe) but in no case less then 1 "
What is role of air gap?
An air gap is to protect the potable water system from contamination from back syphon and it is the best protection possible as there is nothing mechanical to be tested or able to fail (Air gap water distribution) Air break drainage
What is leakage factor?
The Ratio of the total flux ( flux in iron path) to the useful flux (flux in air gap)
What is specific magnetic loading?
Specific magnetic loading is ratio average flux air gap and flux path of air gap:
Why air gap in induction motor?
for flux
What is the importance of air gap in magnetic circuit?
The air gap in a magnetic circuit is important because it increases the reluctance of the circuit, which in turn influences the magnetic flux and magnetic field strength. By controlling the size of the air gap, we can control the level of magnetic flux and magnetic force produced in the circuit. This can be useful in applications where precise control over magnetic properties is required.
What is TPS class current transformer?
TPS Class CT is used for transient performance (TP). TPS class Current Transformer has Low Leakage Flux and there is no limit for remanent flux) further there are also TPX,TPY and TPZ class CTs 1. TPX- No Limit for remanent flux due to nil air gap in the core 2. TPY - remanent flux does not exceeded 10 % due to less air gap in the core 3. TPZ- Having practically null remanent flux because there is large air gap is provide in the Core Er. Anil Prajapati, Protection Engineer,Jaipur RVPNL
What is specific load?
Specific electrical loading is the insertion of impedance into a circuit to change the characteristics of the circuit. In contrast, specific magnetic loading is the ratio between the average flux air gap to the flux path of the air gap. These two terms have nothing to do with each other and are therefore independent of each other.
What is slot harmonics?
in rotating machines the air gap permeance in front of the slots changes with rotating rotor that it change flux in air gap and affect the voltage and current in machine. baradaran from jondishapour university iran
What is specific electric loading?

In contrast, specific magnetic loading is the ratio between the average flux air gap to the flux path of the air gap. These two terms have nothing to do with each other and are therefore independent of each other.
The leakage flux of transformer depends on?
Actually it depends on the air gap between the core and the windings of the transformer. This is the reason why stepped core is used in medium and large transformers as it decreases the air gap between the windings and the core of the transformer.
What is the effect of increasing the length of the air gap in an induction motor?
The magnetic flux that couples the rotor to the stator will weaken significantly reducing the motor's torque.
Why pole shoes are laminated in a dc machine?
they are used to protect windings to get down and spread the flux uniformly.
Protein channels that provide passage for hormones and nutrients between animal cells are termed?
gap junctions
