3.  Introduction of induction motor
 How to induction motor work
 Parts of induction motor
 Process of making motor
 Testing of induction motor

4. AC motors are used worldwide in many applications to
transform electrical energy into mechanical energy
An A.C motor is an electrical motor that is driven by an
alternating current.
It has two basic electrical parts stator and rotor.

5.  3-ph supplied to stator
 Rotating magnetic field generated that moves around
rotor
 Ns =120f /p
 Stationary conducts cuts rotting magnetic field and
emf induced in conductor.
 Rotor is short ckt it circulate a current
 It becomes current in magnetic carrying conductor
placed in magnetic field
 Rotor starts rotating a same direction of rotating
magnetic field

6.  Motor frame
 Stator
 Rotor
 Shaft
 Bearings
 Terminal box

9.  The rotor is the rotational electrical motor component
 It consists group of magnets arranged around a
cylinder with poles facing toward the stator poles

10.  The squirrel cage consist of bars of copper or
aluminums are connected with conducting ring.
 It is entire structure look like cage so it called squirrel
cage rotor.

19.  HV test
 No load test
 Blocked rotor test
 Insulation test
