Machine and robot builders recognize linear motor benefits, but some are reluctant to integrate the components into design because of incomplete understanding of the technology. Here we overcome that ...

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 ...

This application note describes how to implement an exact linear speed controller for stepper motors. The stepper motor is an electromagnetic device that converts digital pulses into mechanical shaft ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...

Today, your average desktop 3D printer is a mess of belts, leadscrews, and pulleys. For his Hackaday Prize entry, [DeepSOIC] is eliminating them entirely. How’s he doing this? With a linear stepper ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

A series of linear stepper motors can provide constant positioning force to 400 N over full travel lengths of 300 mm. The Saia ULE Series is available in unipolar or bipolar configurations and can ...

Described as a low-cost, high-performance component, the company's two-phase, linear stepper motor specifies a 1-mm (0.00004") resolution and promises easy integration into unique and existing ...

A series of low-cost, two-axis linear stepper motor gantries provide repeatability of up to 10 µm. Besides high repeatability, the devices feature low force, high speed, zero backlash, and long system ...

Stepper motors are often used for positioning since they are cost-effective, easy to drive, and can be used in open-loop systems—meaning that they don’t require position feedback like servo motors.

Linear-motor driven plunger pumps are most efficient at transforming mechanical energy to hydraulic work in low-producing and highly deviated wells. Linear-motor driven plunger pumps (LMDPP) are most ...
