We see our share of pitches for perpetual motion machines in the Hackaday tips line, and we generally ignore them and move along. And while this magnetic levitation motor does not break the laws of ...

This diagram comprehensively reveals the entire process from the input of the reference signal to the achievement of precise control within the system. Within this closed-loop control system, the ...

TRAINS that float on air may be the most famous objects borne by magnetic fields. But magnetic forces can also support other, less visible objects: the spinning shafts, for example, hidden at the ...

Magnetic bearings and electrodynamic systems represent a rapidly evolving field in which contactless support of rotating components is achieved through the elegant interplay of magnetic forces and ...

Can you run an electric motor for two years on a single lithium coin cell? [IamWe] figured out how to do it, and even though his donut motor doesn’t look like any motor we’ve ever seen before, it’s a ...

GOTHENBURG, Sweden, Nov. 8, 2023 /PRNewswire/ -- SKF has signed an agreement to acquire 2C Composites, a German high-performance fibre composite supplier. Through the acquisition, SKF (SKFRY) will ...

New 'frictionless' technologies are making industrial equipment such as compressors, turbines, and motors more affordable, efficient and environmentally-friendly. Sometimes to make the world a better, ...

This video is an animation of the principle behind PI’s magnetic linear motors. The magnetic linear motors correspond to a sequence of a number of voice-coil actuators; individual coils can be ...
