Kindly Answer these questions....

Q1- What are the advantages of skewed slots in the rotor of a squirrel cage motor ? Q2- Why is the air-gap between the rotor and the stator of a 3-phase
induction motor kept as small possible? Q3- What will happen if single-phase phasing occurs of a non-working induction condition? Q4- What will happen when a 3-Phase motor continues to run even single after the fuse on one phase is blown? Q5- How can you protect the motor against single-phasing? Q6- Why is slip-ring is preferred over squirrel cage motor? Q7- Is it possible for rotor to run at synchronous speed? Q8- Why is slip very important parameter in 3-phase Induction Motor theory? Q9- How a wound motor machine is run as induction generator? Q10- Why short circuiting rings are used ?
I shall be thanfull to u ...If u answer dese above questions

Too wordy. Comedy requires economy. Try it this way:
Give a man a fire and he'll be warm for a night. Set a man on fire and he'll be warm for the rest of his life.

Yes, that is better.

The larger holes lets the squirrel escape

to make room for the water gap.

If it doesn't work management calls a consultant who asks engineering how to fix it.and charges 10 times what it would have cost to just ask engineering in the first place.

3 shifts of machine operators wonder why they smell smoke before anyone thinks to call maintenance.

use DC moters

why do gentleman prefer blondes?

anything is possible my son if you wish real hard.

engineers get excited when they see a slip.... they don't get out much.

I like the square motors better then the wound ones because they don't roll over.

they cost less then long circuit rings.

the slots are skewed in order to reduce magnetic locking...slip rings are preffered as it is more efficient in increasing your starting torque and you can easily add external resisistance too...the short circuiting rings are used in order to make the resistance small...if you short circuit the slots in parallel resistance decreases...the motor wont run at synchronous speed but it is possible to make it to run thro external means as in synchronous motor....
