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 proliferating. They give machines the absolute highest precision and dynamic performance. Linear motors are very quick and precise for positioning, but are also capable of slow, ...

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 ...

V-738 XY-stages are motorized linear stages driven by linear motors and used in many precision motion and laser machining industrial applications. The XY stage shown above is driven by linear motors ...

Linear motion positioning stages are found in many applications from material handling and assembly to inspection and testing and employ many different technologies. Just looking at the different ...

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 ...

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 ...

Once the control method of choice only in high-performance industrial ac-servo drives, FOC (field-oriented control) is finding its way into lower end industrial and many appliance applications with ...

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.
