This simple motor uses a diode for it’s axis, enameled wire wrapped into a small coil for the electromagnet and Turkish needle lace (Igne Oyasi) for both structure and support. The diode provides an electrically separated axis, around which the coil can both spin and receive it’s power. The electrical properties of the diode mean that when powered the wrong away around (and not above it’s backwards current rating) it represents a single axis with two conductive leads coming of either side. The leads are physically connected through the diode, but are NOT electrically connected! The ends of the enameled wire that has been wrapped into a small tight coil are stripped (uninsulated) and curled and soldered into little rings that become both the electrical contact leads for the electromagnetic coil, as well as the joints between the coil and the diode axis.
This motor was made during the 2014 E-Textile Summercamp.
