Step 4

PURPOSE:
    To wire the motors
MATERIALS:
  • 3 sealed motors
  • 3 film cans with caps
  • Tether wire
  • Solder
TOOLS:
  • Drill
  • 5/32" drill bit
  • Soldering iron
PROCEDURE:
  1. Take 5/32" drill bit and drill holes in the center of the bottom of the 3 film cans and the centers of the 3 film caps (Fig 10A).
  2. Strip about 15" of sheath from the tether wire, being careful not to nick any of the inner wires. Separate the four twisted pairs as shown on previous page.
  3. Thread 6" of twisted pair through the hole in each film cap, and tie a knot inside the cap for strain relief (Fig 10B).
  4. Strip 1/4" of insulation from the end of each wire. Solder wires to terminals of the sealed motor: Colored wire to (+), white wire to (-) (Fig 10C). Repeat for each motor/tether wire. (Brown wire does not get attached to a motor).
