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, ...

Once considered expensive and exotic, linear motors are at last becoming valuable workhorses in a variety of OEM applications. Besides delivering nanometer precision in the semiconductor and machine ...

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 ...

Any electrical motor, from an idealized viewpoint, consists of two sets of magnets—one set stationary, one set free to move—placed in special geometric relation to one another. For most practical ...

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 ...

FORT WORTH, Texas--(BUSINESS WIRE)--Smarter energy company Linear Labs has launched production of its new High Torque and Ultra High Efficiency electric motor and new intelligence drive system, called ...

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 ...

When most engineers hear the term motor they most-naturally think of rotating arrangements such as brushed DC, brushless DC, stepper, or variable-frequency prime movers. But a motor doesn’t have to be ...

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 ...
