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, ...

We’ve all heard linear motors, like those propelling Maglev trains, described as “unrolled” versions of regular electric motors. The analogy is apt and helps to understand how a linear motor works, ...

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 ...

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 ...

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 ...

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 ...

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 ...
