DC Brushless pulse motor powered by a Rodin coil. The special winding is called the April Wind. Its geometry was discovered by Randy Powell during the course of his continuing work with Marko Rodin's Vortex Math concepts and mapping of a number based geometry onto the surface of a toroid.
Visist Randy's videos also here on Youtube.

The toroidal wound coil has 6 separate wires with 12 turns each. The wires do not touch each other or cross over each other. It has slightly less than 1 ounce of #26 gauge solid copper wire total, or about 100 feet. The total series resistance is 3.1 ohms. The motor runs on 12 volts dc, and uses about 650 ma at 21,000 RPM. Runs smoothly and has good torque at all speeds, though at the lower RPMs it uses more current. The rotor is a 1 inch neodymium cylinder magnet magnetized thru the diameter. A schematic is included in the video. checkout new site vortexspace.org for good info, files, pictures, etc.
The Hall sensor is n AH175-PL-B-B from Mouser electronics
