Induction motor
 Aninduction motor works on
 transforming action.

 The stator works as the primary while
 the rotor works as the secondary.

 It   is also called asynchronous motor.
 It   consists of two parts:

       1. Stator - It is the stationary part of the
          motor.


       2. Rotor - It is the rotating part of the
          motor.

Induction motor

  • 3.  Aninduction motor works on transforming action.  The stator works as the primary while the rotor works as the secondary.  It is also called asynchronous motor.
  • 4.  It consists of two parts: 1. Stator - It is the stationary part of the motor. 2. Rotor - It is the rotating part of the motor.
  • 6. Slots Tooth Stator Stamping
  • 7. SLOTS CORE WINDINGS
  • 9. Stator has three main parts:  Outer Frame – It is the outer body of the of the motor. It protects the inner part of the machine.  Stator Core – Built up of high grade silicon steel. Carries the alternating magnetic field.  Stator winding – Has a three phase winding.
  • 11.  There are two types of rotors which are employed in 3 – phase induction motor.  Squirrel Cage Rotor.  Phase Wound/ Slip Ring Rotor.
  • 14.  It consists of a laminated cylindrical core having semi closed circular slots at the outer periphery.  Copper or aluminum bar conductors are placed in these slots and short circuited at each end by copper or aluminum rings called short circuiting rings.  The rotor winding is permanently short circuited and it is not possible to add any external resistance.
  • 15. The rotor slots are not parallel to the shaft but skewed to –  Reduce humming . Provide smoother torque for different positions of rotor. Reduce magnetic locking of stator and rotor.
  • 21. It is also called SLIP RING ROTOR  Consists of a laminated core having semi closed slots at the outer periphery and carries a 3-phase insulated winding.  The rotor is wound for the same number of poles as that of stator.  The three finish terminals are connected together forming a star point and the three star terminals are connected to three slip rings fixed on the shaft.
  • 23.  Principle of Operation A rotating field is set up in the stator when a 3- Phase supply is given. The stationary rotor cut the revolving field and due to electromagnetic induction an e.m.f. is induced in the rotor conductor. As the rotor conductor is short circuited current flows through them. It becomes a current carrying conductor in magnetic field and start rotating.
  • 24.  Slip  Induction motor rotor always rotate at a speed less than synchronous speed.  The difference between the flux (Ns) and the rotor speed (N) is called slip. % Slip = (Ns – N) 100 N Slip speed = Ns – N
