Question 41Electricity & Electronics - Assistant Engineer

The correct answer is A) Series-wound. A series-wound AC single-phase motor can also operate on direct current (DC) because the series-wound configuration allows the motor to function on either AC or DC power. The series-wound motor has the field winding and armature winding connected in series, which enables it to work with both alternating current (AC) and direct current (DC) supplies. The other options are incorrect because: B) Repulsion-start motors are designed to start using repulsion principles and then switch to an induction mode, C) Shaded-pole motors rely on a shading coil to produce a rotating magnetic field, and D) Split-phase motors have a starting winding in addition to the main winding, which is not suitable for DC operation.
