What does tape and line mean on an electric motor wiring diagram?

In an electric motor wiring diagram, "tape and line" is a notation used to indicate how multiple motor windings are connected to each other. When you see "tape" or "line" on a diagram, it refers to the ends of the winding wire that are connected together. Here's what they mean:

Tape: The "tape" end of the winding wire is typically the beginning of the winding, where the wire starts.

Line: The "line" end of the winding wire is typically the end of the winding, where the wire finishes.

When windings are connected in series or parallel, the "tape" end of one winding is connected to the "line" end of another winding. This creates a continuous path for the electric current to flow through all the windings.

The "tape and line" notation helps electricians and technicians identify the proper connections between motor windings, ensuring that the motor operates correctly. It also allows for easy troubleshooting in case of any issues with the motor's wiring.
