The working principle of three phase induction motor supplier in UAE is essentially based on the concept of mutual induction as in case of transformer. The significant difference in between them is that transformer is fixed in nature i.e. it does not have any type of moving components whereas Induction Motor is a dynamic one. An additional distinction between a Transformer and an Induction Motor is that Transformer has focused winding whereas Induction Motor has distributed winding. Working Principle:
Three stage air conditioner supply offered to Induction Electric motor generates a consistent amplitude Rotating Electromagnetic field which revolves at simultaneous speed with respect to stator.
This rotating area cuts the blades conductors which are fixed initially as well as causes an emf based on Faraday's law of electro-magnetic induction.
Emf drives existing in rotor conductors as they are short circuited by end rings.
So currently we see that current carrying conductors of blades are placed in an electromagnetic field, hence force acts upon each of these conductors according to F = idlxB where F is the force on a conductor lugging existing I and also size dl.
The resultant of forces on all the conductors produces a revolving effect on the rotor i.e. torque.
Now the inquiry develops is “In which direction does the blades rotate?” This can be easily responded to if from Lenz's regulation. As per Lenz's Law “effect opposes the reason”.
In Induction Electric motor, reason is ‘rotating electromagnetic field reducing rotor conductors or the change reducing activity' & end effect is the ‘torque'.
So, for result i.e. torques to oppose the cause i.e. flux reducing action, torque generated makes the rotor turn parallel as that of the RMF. Thus the family member velocity in between the rotor as well as revolving electromagnetic field ends up being (Ns– Nr) where Ns = Synchronous speed of turning electromagnetic field and also Nr = Rate of blades.
Currently the point is, can the speed of Rotor come to be equal to the concurrent rate?
The rate of Rotor can not be equal to the concurrent speed as if it takes place after that the loved one speed between the turning magnetic field as well as the blades = (Ns– Nr) =0 and for that reason blades and revolving electromagnetic field are stationary per other which subsequently means no flux cutting and thus no emf as well as no existing in the rotor bars. Therefore torque will not be created if the rate of blades becomes equal to the concurrent rate in Induction Motor.
