The easiest way to design a linear-motion system is to add components one by one. Then, step-by-step calculations relate input to power dissipated moving a load in a specific amount of time. Linear ...

PCBs are exceptionally cheap now, and that means everyone gets to experiment with the careful application of copper traces on a fiberglass substrate. For his Hackaday Prize entry, [Carl] is putting ...

Linear motors are becoming increasingly practical for general motion. Many are used for long strokes of a few feet or more. One new design, however, where the magnets move relative to a stationary ...

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 ...

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 ...

Essentially, a guide wheel is a ball bearing that has a special shaped outer race. The inner and outer races of ball bearings are a framework with a groove for the balls to rest in. Burke explained ...

RC servos are handy when you need to rotate something. You can even modify them to rotate continuously if that’s what you need. However, [Roger Rabbit] needed linear motion, but wanted the simple ...

In recent years industry has shown growing interest in linear ultrasonic piezoelectric actuators and ultrasonic drives. Well-known manufacturers of micropositioning systems have increasingly put ...
