How do you know when something's a genius invention? For me, it’s when I see it and instantly go: why didn’t I think of that?

This paper presents a control system design for a particular form of variable-reluctance spherical motors, referred to here as a spherical wheel motor (SWM). The method decoupling the spin from the ...

A double-layer permanent magnet spherical motor (PMSM) with same spatial distribution of stator poles and rotor poles is designed based on spherical harmonic theory in this article. The stator coils ...

Many of you have seen the process of making this rotary valve engine with different intake and exhaust system and how I tried to start it. After so many attempts to start this engine, I was ready ...
