Fun with Magnets & Hard Drives | Lenz's Law Demo - Magnets Levitating on...

Levitating a magnet above spinning aluminum plates Lenz's Law demonstration DIY.

Demonstration of Lenz’s Law principle by levitating a magnet above spinning aluminum hard drive platers.  

Lenz’s Law description short and simple:

The magnet induces a voltage in the aluminum plates due to the relative motion.

This induced voltage creates an opposing magnetic field which repels the magnet and cause it to levitate.

This is just a quick preliminary lenz law demo before we build a Lenz’s Law demonstration apparatus for a Lenz’s Law science project.

Running a 2GB Server Drive - BLDC Motor Control

Running an old Brushless DC (BLDC) Hard Drive Motor with a ESC, RC electronic speed control.

These are decades old hard drives with large aluminum platers that I have been meaning to spin up for years to do some magnetic projects.  I have larger older 2 GB server drives I plan to spin up next to make a magnetic levitator.

Hard Drive Motors are Brushless DC Motors (BLDC Motor) which are 3 phase motors.

BLDC Brushless DC motors can be sensored or sensorless BLDC.  These hard drive BLDC motors are sensorless.

The Hard Drive Motors are being driven by an RC ESC (Electronic Speed Control) powered by a regulated power supply and controlled by a servo controller  but could be an RC transmitter and receiver as well.
