Construction of three phase induction motor

Question 1

3 phase induction motor consists of

Answer 1

stator
rotor

Question 2

what is in stator

Answer 2

magnetic core, windings, shell

Question 3

what is in rotor

Answer 3

magnetic core with conductors in a cage configuration or windings connected to slip tings, shaft to be connected to mech system, bearing, cooling fan

Question 4

constructing a magnetic core

Answer 4

to reduce eddy loss, made of electrical steel lamination sheets, slots are uniformly distributed around the stator’s internal and rotors external peripheries

Question 5

stator winding set

Answer 5

3 phase windings each with sane muber of distributed coils having identical number of turns shifterd to have angle of (2pi/3) where p denoted pole pairs

Question 6

types of rotors

Answer 6

squirrel cage rotor, caged rotor, wound rotor

Question 7

what is in a squirrel cage rotor

Answer 7

series conductor bars laid into slots carved around rotor

Question 8

wound rotor

Answer 8

complete set of 3phase windings that resemble windings on stator
star connected and the ends are ties to slip rings
rotor windings are shorted to a set of 3 phase brushes on the slip rings
