Induction Motor:No of rotor poles not equal to no of stator poles

Click For Summary
SUMMARY

The discussion centers on the operation of induction motors when the number of rotor poles does not equal the number of stator poles. In Case 1, with 2 rotor poles and 4 stator poles, the induction motor will operate, as there are sufficient stator poles to create a magnetic field. In Case 2, with 4 rotor poles and 2 stator poles, the motor will also run, but the interaction will differ due to the mismatch in pole numbers. The key takeaway is that as long as there are poles to align, the induction motor will function effectively.

Consider 2 cases

case 1: no of rotor poles = 2
no of stator poles =4

case 2: no of rotor poles = 4
no of stator poles =2

What will happen in case 1 & 2 ? Will Induction motor run?

It's OK so long as there are poles to match up.

... in this example there are fewer poles in the rotor than in the stator.
