3-phase stator winding is fed from a balanced 3-phase supply, a rotating magnetic field (RMF) is produced in the motor. This RMF rotates around the stator at synchronous speed which is given by, SynchronousSpeed,NS=120fP The RMF passes through the air gap and cuts the rotor conductors, which as yet are stationary. Due to the relative motion between the RMF and the stationary rotor conductors, EMFs are induced in the rotor conductors. As the rotor circuit is closed with short-circuit so currents start flowing in the rotor conductors. Since the current carrying rotor conductors are placed in the magnetic field produced by the stator winding. As a result, the rotor conductors experience mechanical force.

5. Interdiction
• A 3-phase induction motor is an
electromechanical energy conversion device
which converts 3-phase input electrical
power into output mechanical power.
• Induction motor consists of a stator and a
rotor.
• Stator carries a 3-phase stator winding
• Rotor carries a short-circuited winding
called rotor winding.
• Stator winding is supplied from a 3-phase
supply.
• Rotor winding drives its voltage and power
from the stator winding
• through electromagnetic induction and
hence the name.

7. Principle of Operation
• 3-phase stator winding is fed from a balanced 3-phase supply, a rotating magnetic field (RMF) is produced in
the motor. This RMF rotates around the stator at synchronous speed which is given by,
SynchronousSpeed,NS=120fP
• The RMF passes through the air gap and cuts the rotor conductors, which as yet are stationary. Due to the
relative motion between the RMF and the stationary rotor conductors, EMFs are induced in the rotor
conductors.
• As the rotor circuit is closed with short-circuit so currents start flowing in the rotor conductors.
Since the current carrying rotor conductors are placed in the magnetic field produced by the stator winding.
As a result, the rotor conductors experience mechanical force.

8. Slip in Induction Motor
 The sum of the mechanical forces on all the
rotor conductors produce a torque which
moves the rotor in the same direction as the
rotating magnetic field. Hence, in such a
way the three phase input electric power is
converted into output mechanical power in a
3-phase induction motor.
 Rotor can never reach the speed of stator
flux.
 If it did, there would be no relative speed
between the stator field and rotor
conductors,
 no induced rotor currents and,
 no torque to drive the rotor.
 The friction and windage would immediately
cause the rotor to slow down. Hence, the
rotor speed (N) is always less than the stator
field speed (Ns). This difference in speed
depends upon load on the motor.

9. Advantage & Disadvantage
 It has simple and rugged construction.
 It requires less maintenance.
 It has high efficiency and good power factor.
 It is less expensive.
 It has self-starting torque
 The 3-phase induction motors are constant speed motors; hence
their speed control is very difficult.
 3-phase induction motors have poor starting torque and high
inrush currents (about 4 to 8 times of the rated current).
 They always operate under lagging power factor and during
light loads, they operate at very worst power
