Electro-permanent magnets (EPMs) are pretty nifty concepts, and if you aren’t familiar with them, they are permanent magnets ...
Imagine a quadcopter hovering above a payload – a can of beans, perhaps. The ‘copter descends onto the payload, activates an electromagnet, and flies away with a hobo’s dinner. Right now, this is a ...
Damping vibrations is crucial for precision experiments, for example in astronomy. A new invention uses a special kind of magnets to achieve this -- electropermanent magnets. They consist of a ...
designed to be nearly a drop-in replacement of the old EPM v3. Just like its predecessor, the EPM 4 is a solid-state, zero-maintenance electropermanent magnet with no moving parts in its construction.
A number of readers questioned the veracity of the technology presented in this article. To address their concerns, we did a follow-up, which can be found here. Permanent magnets are an integral part ...
Shown for the first time at MACH 2016 will be new range of Italian-made products that incorporate permanent-electro magnets, designed for workholding on machine tools and for handling sheet, bar and ...
Magnetic couplings transmit high torque with no physical contact, and they disengage smoothly when load gets too high. Generally speaking, the couplings use magnetic power in three different ways; ...
