Full Answer

To read an electric motor diagram:

  1. Understand symbols for wires and connections
  2. Wires are represented on electric diagrams by lines. A wire is shown as a single line, a two-line bus is shown as two lines, a three-line bus is shown as three lines and so on. Connections between lines are shown as dots over the junction. A terminal is shown as a larger, empty circle.

  3. Recognize symbols for cells and batteries
  4. A battery is shown on an electric motor diagram as two or more lines intersecting the wire line. They are drawn perpendicular to the wire with a gap between them. A cell is shown as a similar set of intersecting lines with plus and minus symbols.

  5. Learn other symbols
  6. There are numerous other symbols that appear on electric diagrams, among them the circled M for a motor. Other similar symbols include an A inside a circle for an ammeter, a V inside a circle for a voltmeter, and a G inside a circle for a Galvanometer. A switch is shown as two circles with the line representing the wire unconnected between them at an angle.
