Simple high speed motor

June 4th, 2011

This is a quick motor I made using a single phase brushless motor controller IC (AH5798-yg) a coil of wire (100 turns of 38 awg)  and a magnetic sphere (Neodymium Iron Boron, N42). Based on the sound (via my FFT app on my iphone)  it is spinning at either 74400 or 37200 rpm.
