Shaft design veteran Alex Dee co-founded Aretera with a straightforward but subversive thesis: Stability and stiffness aren't the same. The post The story behind Aretera’s first-of-its-kind shaft ...

Linear motors are synchronous motors: Current is applied to the coil to form an electromagnet. The coil then synchronizes itself to the magnetic field generated by the permanent magnets in the magnet ...

They're lightweight with straightness and lateral stiffness that boost stability at higher speeds. Line shafts, also known jackshafts and torque tubes, span long distances to connect other power ...
