First of all You won't find here any information on high speed BLDC motor driving. For that purpose You need to know rotor's position, so You have to measure back-EMF or use Hall sensors (not needed here). For basic info about driving BLDC motors here is best "classic" articles on internets: Driving a three-phase brushless DC motor with Arduino – Part 1. Theory Driving a three-phase brushless DC motor with Arduino – Part 2. Circuit and Software http://www.instructables.com/id/BLDC-Motor-Control-with-Arduino-salvaged-HD-motor/ I used specialized triple half bridge IC L6234 ... Read more
