Question

Which of the following starter can sufficiently start the DC series motor?

(a) 3-point starter

(b) 4-point starter

(c) 2-point starter

(d) Cannot be determined

This question was addressed to me during an internship interview.

Enquiry is from Starting of DC Motors topic in chapter DC Motors of DC Machines

Answer 1

Correct choice is (c) 2-point starter

Best explanation: 2-point starter is enough to start the DC series motor. Since armature and field winding are in series already high armature current will not flow. No requirement of 3 or 4-point starter in DC series motor.
