Magnetic levitation demonstrated using a Dremel tool spinning a magnet at 266 Hz. The rotor magnet is 7x7x7 mm3 and the floater magnet is 6x6x6 mm3. This video show the physics described in the work ...
The number of interesting and innovative mechanisms that 3D printing has enabled always fascinates us, and it’s always a treat when one of them shows up in our feeds. This axial flux magnetic gearbox ...
•Turn the rotor magnet in the direction of normal rotation until the pointer indicates 8 degrees past neutral. Points should then just start to open at this position. A piece of ordinary cellophane, ...
An image of the experiments showing a coil that the researchers used to measure the frequency at one point. (Courtesy: R Bjørk) Magnetic levitation is already employed in systems such as Maglev trains ...
In a Brushless DC (BLDC) motor system, an electronic mechanism is required to commutate the system. Unlike a Brush DC motor system, the permanent magnet is located at the rotor and the windings are ...
Magnets, typically using rare earth metals like neodymium, are found at the heart of most electric vehicle motors. It's nice to have a permanent source of powerful rare earth magnetism in your rotor, ...
Disc motors are permanent-magnet stepping motors that exhibit performance comparable to that of hybrid motors. Rotors in disc motors are thin (typically less than 1-mm) discs, unlike the cylindrical ...
