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 ...

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 ...

A new weld head from Emhart Fastening Teknologies features a linear-motor drive that precisely times and controls lift heights, plunge velocity, and depth penetration of each attachment during welding ...

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 ...

Dunkermotor, now part of AMETEK Precision Motion Control, has released its first ServoTube linear motors and actuators catalog with technical specifications and drawings that cover 1,346 standard ...

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 ...

While current control and PWM switching play the most direct role in driving brushless DC motors, the motion profile and ...

Moticont has added two linear motors to it's SDLM Series of high speed direct drive linear motors which are also know as Electric Cylinders. Feb. 7, 2017 2 min read Moticont has added two linear ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motors ...

SICK has released safety-certified versions of its TTK70 and TTK50 magnetic absolute linear encoders with Hiperface° interface, widening the opportunities for accurate, absolute motor feedback systems ...
