Sir, I have one doubt. Is there any way to find the value of demagnetizing armature turns (AT_D per pole) if we don't have the value of forward lead of brushes (Theta_m) ?

[@adityakulkarni314]

If somebody has to manufacture a new motor. Can he determine the value of Theta_m without any trial ?

this is wrong because since the formula was derived for 2 pole but here it is 4 pole so the answer should be 752*2

Thank you sir nice explanation 🙂

Thank you so much sir 😊

Sir kindly provide ppt link in the comments or description. Thank you for nice explanation.

Very clear..

Sir kindly provide how we calculate Demagnetization time constant and stator residual voltage after automatic demagnetization

[@akhilt9870]

Problem 1 is wrong because no. Of poles were taken wrongly
