How are motor windings shown on connection diagrams?

• A. As coils or as a diagram showing internal connections (Wye and Delta) with leads numbered T1, T2, T3
• B. Only as a simple rectangle with terminals
• C. As a single straight line symbol
• D. Not shown in connection diagrams

Answer: (A)

Motor windings on connection diagrams are shown as coils or as a schematic of the internal wiring, including how the windings are connected inside (such as Wye and Delta configurations) with the leads labeled (often T1, T2, T3, etc.). This lets you see both the physical coil arrangement and how the windings tie together, which is essential for configuring the motor for different voltages and rotation directions. A simple rectangle with terminals or a single straight-line symbol wouldn’t reveal the winding structure or the internal connections, so those representations don’t accurately show how the windings are connected. The depiction using coils or an internal-connection diagram with labeled leads best matches how windings are represented on connection diagrams.
