The first linear motor was conceived by Wheatstone more than 100 years ago. But large air gaps and low efficiencies prevented linear motors from being widely used. Though they still have relatively ...

Linear motors are very quick and precise for positioning, but are also capable of slow, constant-traverse speed for machine heads and slides, as well as tool and part-handling systems. A variety of ...

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 ...

For medium- and high-voltage applications, Kollmorgen’s latest DDL motor offers a new capability to support 400/480V AC-powered applications. It delivers a continuous force range up to 8,211 N and ...

The things often prioritized in the list of requirements of design engineers from the precision automation sector are different from those of their colleagues in the instrumentation industry. Dynamic ...

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 ...

The two most important electric motors are the ac induction motor and the permanent magnet (PM) brushless synchronous motor, also known as the brushless dc or ac servo motor. These motors have ...

This document written by Steve Bowling, Application Segments Engineer at Microchip Technology, discusses how motor works and describes the AC induction motor, variable-speed ACIM control, and FOC.
