This video showcases a simplified 3D printed cycloidal drive, known for its high torque density with an 8:1 gear ratio. The ...

A team of physicists has pushed the limits of quantum control by cooling the rotational motion of a nanoscale object to its ...

Abstract: In safety-critical control for permanent magnet synchronous motors (PMSMs), the overshoot after adding a spontaneous load is a crucial metric, leading to the unexpected motion of driving ...

Abstract: The spin-transfer torque magnetic tunneling junction (MTJ) technology may pave a way to a universal memory paradigm. MTJ devices with perpendicular magnetic anisotropy have the potential to ...

A direct current flows in only one direction. On a voltage-time graph this would appear as a straight horizontal line at a constant voltage. Car batteries, dry cells and solar cells all provide a ...

Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials. Electromagnets - AQA ...
