World's Smallest Brushless Motor

Single phase submicro brushless motor, made from rewound wristwatch coil wire and the A1442 speed controller ic chip. Magnet is .5mm x 1mm, smallest available, shaft from .007" music wire, hypodermic tubing for bearings. Propeller is 8 mm diameter, made from basswood. A complete build thread with many photos on this and other motors at westknoxrc.com and rcgroups.com, posted by "shagrug". Many more vids are posted at vimeo.com, in shagrug's folder there.

You're 50 years too late and your motor's too big. In 1960 William McClellan, inspired by a now-famous speech by Nobel physicist Richard Feynman about the possibilities of very small technology, built a motor 1/64" (.38mm) on a side (using only standard micromachining technology, not modern nanotech).

Any piece of iron or (non-stainless) steel can be made into a magnet by subjecting it to a strong magnetic field, so make your own to go smaller.

my fan is too loud.....this one is better

@Yunituber omfg ant airplane would be so beast id buy that

[ob1kanukie]

Nice work!!

@Yunituber or wrap the body with solar paper

[Hallootjesful]

make 12 of those and now you have a v12
