Hafedh Alabdulaal, an Electronic Engineering student at Auckland University of Technology (AUT) in New Zealand, did his final-year project on levitation with induction, supervised by Dr. Craig Baguley in the Electrical and Electronic Engineering Department.
As Ultraflex is an industry expert in levitation with induction, Hafedh and his project partner Ali reached out to us about detailed calculations for levitating a 12g piece of aluminum. We provided the team of students with advice and our levitation calculation formulas to help them reach their goal. They built the necessary circuitry and achieved a current of 165A RMS through the levitation coil driven by an H-bridge at 100kHz.
Their circuit, with the levitation coil fitted as the secondary winding of the step-up output transformer.
The achieved current was not yet enough to achieve levitation of their piece, but the project will be running again next semester with new students building on Hafedh and Ali’s work, who are now graduating. Ultraflex congratulates Hafedh and Ali on their graduation and on tackling such a challenging project. We wish luck to the next students that continue the induction levitation project.
