Procedure:

First we will make a rotor coil and hangers.

Materials / Main Page

 

Step 1:

• Make a rectangular coil of #28 magnet wire.
• It should have 5 to 10 turns and measure approximately ½” by 1”.
• Wrap the ends of the wire around the short sides of the coil. Secure it with about three wraps, and leave the two ends extended in opposite directions.
• Adjust the coil so that the ends form an axis, around which the coil can freely rotate. Make sure the coil is balanced.

Step 2:

• Use sand paper to remove the enamel coating from only one edge of each axial wire on the coil.
• Be sure to remove the enamel from the same edge of both wires.

 

Step 3:

• Strip the plastic jacket from two equal lengths of #28 telephone hook up wire.
• Bend each wire into a long U shape approximately 1/8" wide.
• Bend ¼" inch of the bottom of the U shaped wire back onto itself to make a small hanger for the coil axial leads.
