This is the Mega 22/30/3E. It is a 3 Phase, 6 pole, permanent magnet inrunner, with a hardened steel shaft riding on high quality ball bearings. The lightweight rotor is loaded with neodymium magnets and wrapped in kevlar and dynamically balanced. The kevlar hold the magnets in place, withstanding RPMs in excess of 35,000. The hand wound stators and tight tolerances of the rotor / stator all contribute to its 86% efficiency rating.
