Explain fractional slot winding and related calculations?
here spp(slots per pole per phase)is a frictional no. it is a double layer winding while m=s/3p is non integer in a frictional slot winding.
How high is a tree that cast a 24ft shadow at the same time an 8ft pole cast a shadow which is 12ft long?
For pole: ratio of shadow to pole = 12/8 = 1.5 So, for tree, ration = 1.5 24/H = 1.5 so H = 24/1.5 = 16 ft
How do you measure the diameter of a metal pole?
You could use a pair of calipers. Alternatively, measure its circumference using a piece of string and divide the measure by pi.
How can you travel 3 miles south and then 3 miles east and then 3 miles north and be at your starting place?
You can start near the South Pole - 3 miles North of any point on a latitude that encircles the earth an integer number of times in 3 miles; or you can start at the North Pole.
A building casts a 7.5m shadow at the same time that a 40m pole casts a shadow of 3m. How high is the building?
Ratio of shadows = 3m:7.5m :: 1:2.5 So, the ratio of the heights (in the same order) is 1:2.5 ie Ht(Pole):Ht(Building) = 40m:Ht(Building) = 1:2.5 So Ht(Building) = 2.5*40m = 100 metres
Explain fractional slot winding and related calculations?
here spp(slots per pole per phase)is a frictional no. it is a double layer winding while m=s/3p is non integer in a frictional slot winding.
What is concentrated winding?
a winding is called concentrated winding when the number of slots per pole per phase is fractional
What is an amortisseur winding?
An amortisseur winding is a squirrel cage winding placed near the surface of the pole faces of a synchronous motor.
What is the height of the telephone pole if shadow is 20 feet long and the angle of elevation from the groung if 70 degrees?
Using the tangent ratio height of telegraph pole is 55 feet to the nearest integer.
What is pole core?
A pole core is a word often used in dc machines which provides space for field winding
What is the difference between concentrated and distributed winding?
concentrated winding:-slots/pole/pshas=1 , i.e equal to 1 distributed winding:slots/pole/phase>1 , i.e grater than 1
How many parallel paths in a wave winding of a 4 pole dc motor?
2
What song has the lyrics i see you winding and grinding up on that pole?
"i wanna love you" by akon
How induction motor is made self starting?
just put a auxilari winding on the rotor (in the salient pole)..
What is the best place to go looking for South Pole jeans?
go to the south pole and find a pair.
Why do magnetic pole occur in pair?
this is so easy. because they are poles. otherwise it would be a magnetic pole.
What is pole winding?
Pole winding refers to the arrangement of coils or windings around the poles of an electrical machine, such as a motor or generator. These windings create a magnetic field when current flows through them, which interacts with the magnetic field of the machine to produce mechanical motion or electrical energy. The configuration and number of poles, along with the winding design, significantly influence the machine's efficiency and performance characteristics.
