We’ve seen plenty of motor projects, but [Jeremy]’s DIY Tubular Linear Motor is a really neat variety of stepper motor in a format we certainly don’t see every day. It started as a design experiment ...

Linear actuation, or moving a load in a straight path, can be accomplished using a variety of methods. Each actuator type has features and performance capabilities inherent in the base technology ...

For rotary or linear motors, motion is produced in the same way and the same basic physics and electromagnetic forces apply. The theory that produces "torque" in a rotary motor produces "force" in a ...

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 ...

A line of Nippon Pulse’s linear shaft motors that features analog Hall effect sensors to enable closed-loop positioning without a linear encoder. Linear motors can be described as uncurled 3-phase ...

Certain approaches simplify the sizing, integration, and protecting of tubular linear motors destined for thermally constrained applications — and they don’t necessarily rely on the use of large and ...
