1.	Calculate the flux produced by the DC series field winding using the following data: Ia=5 A, N=23, R=23.(a) 5 Wb(b) 6 Wb(c) 9 Wb(d) 8 WbThe question was asked in an interview for job.I need to ask this question from Dynamic Braking of DC Series Motors in portion Braking of DC Motors & Induction Motors of Electric Drives
Answer» The correct option is (a) 5 Wb To EXPLAIN I would say: In DC series motor, FIELD WINDINGS are CONNECTED in series with the armature circuit. F=NIa=R∅. Ia∝∅. ∅=F÷R=5 wb.
