Active Magnetic Bearing: Tripod Floater v2.0
Meindert Norg from Norg Consulting (www.NorgConsulting.com) demonstrates his active magnetic bearing, Tripod Floater. The closed-loop system uses three Pololu 18v15 high-power motor drivers as PWM amplifiers to power the magnetic coils that keep the module floating beneath the metal plate. By Meindert Norg, August, 2009. February, 2010 update: the Tripod Floater is now wireless! Version 2.2 video
