Tiny magnetic microrobots spinning in liquid can generate fluidic torque strong enough to move gears and objects without any physical contact.
Spin-torque-induced dynamics at fine-split frequencies in nano-oscillators with two stacked vortices
The gyrotropic rotation around the equilibrium position constitutes the fundamental excitation of magnetic vortices in nanostructures. The frequency of this mode varies with material and sample ...
When it’s time to specify a high-performance motor that offers both precise positioning and cost efficiency, stepper motors offer many advantages over DC motors thanks to their brushless technology.
