In a single-phase electric motor, the primary type of windings utilized are armature windings. These windings play a crucial role in converting electrical energy into mechanical energy, as they are responsible for creating the magnetic field when electricity flows through them. In a single-phase motor, the armature windings are usually situated on the rotor or stator, depending on the design of the motor.

Field windings are typically associated with motors that require a separate winding to produce a magnetic field, as seen in many DC motors, but in single-phase AC motors, the armature itself is designed to generate the necessary magnetic field. Coil windings are a more generalized term and could refer to any kind of winding configuration, while magnetic flux windings are not a standard term used in the context of single-phase motors. This specificity in terminology helps clarify the role of armature windings in the operation of single-phase electric motors.
