Linear motion is central to many moving machines, and the direct-drive nature of linear motors can simplify overall machine design in these applications. Other benefits include improved stiffness, ...

To run a stepper motor smoothly, it's necessary to apply linear acceleration. However, conventional algorithms to generate linear acceleration require complicated mathematics, which makes it difficult ...

[Raul] built a cheap linear actuator out of a drawer slide and a surplus flatbed scanner. A few builds we’ve seen, like the PCB drill press or the horribly inefficient thermostat, used linear ...

The PFL20 Linearstep is an efficient, high thrust tin-can linear actuator with just a 20mm diameter and a bipolar winding. It is RoHS-compliant, has a 30/60-mm effective stroke, and can put out 6 N of ...

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 ...

MOTION CONTROL: H2W Technologies’ compact, industry-standard, 12 lb Linear Steppers (53 N continuous Force, 16 lb, 71 N peak force) travel at 80 inch/sec (2m/sec), with 1 micron (0.00004 inch) ...

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 ...

Tailored for use with the company's tin-can rotary and linear stepper motors, the NP3775 debuts as a bipolar chopper driver and the NP7380 as a state logic (phase distribution) chip. The NP3775 dual ...

The stepper motors provide constant positioning force to 400 N over full travel lengths to 300 mm in ambient temperatures ranging from -15 to +60°C. Compact 55 x 55 mm design and NEMA 23 mounting ...

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 ...
