The industry standard method used to reverse the rotation of a 1Ø AC motor is to use a reversing starter to change the current flow direction through the ___ winding.

• A. Start
• B. Run
• C. Field
• D. Armature

Answer: (A)

The industry standard method for reversing the rotation of a single-phase alternating current (1Ø AC) motor typically involves a reversing starter, which primarily manipulates the current flow through the start winding. In single-phase motors, there are usually two windings: the run winding and the start winding. The start winding is utilized to create a phase shift that helps in establishing the initial rotation when the motor is powered. By reversing the current through the start winding, the phase relationship between the windings is altered, which subsequently changes the direction of the rotating magnetic field. This results in the motor reversing its rotational direction. The run winding continues to operate while the motor is running, and changes in current flow through this winding alone do not effectively reverse the rotation. Additionally, terms like "field" and "armature" pertain more commonly to direct current (DC) motors or other types of alternating current motors, where the concepts of fields and armatures apply differently compared to single-phase AC motors. Therefore, the action taken on the start winding specifically allows for the intended effect of reversing the motor's rotation.
