Explain why a single-loop armature has little practical value for commercial motor applications, and what can be done to address this problem.
What will be an ideal response?
For a single-loop armature, the torque applied to the motor shaft is weak and pulsating even with an electromagnetic field. The undesirable pulsations in torque of a single-loop armature can be eliminated by adding more loops and the necessary commutator segments.
