1.	In dynamic braking, DC series motor behaves as a ____________(a) Separately excited motor(b) Transformer(c) Induction motor(d) ThyristorThis question was addressed to me in class test.Query is from Dynamic Braking of DC Series Motors topic in division Braking of DC Motors & Induction Motors of Electric Drives
Answer» The correct choice is (a) Separately excited motor The explanation: In dynamic braking, DC SERIES motor behaves as a separately excited motor as the motor ARMATURE is disconnected from the source and CONNECTED across RESISTANCE RB.
