Keith Kowalski is Vice President of Technology and Robert Pulford is an Application Engineer with Haydon Switch and Instrument Inc. The linear step motor, or linear actuator, first came into being in ...

A new linear/rotary dual-motion actuator has been designed to provide incremental rotational and linear movement of the output shaft. The Size 14 actuator has two degrees of freedom of movement that ...

Rotary motor motion is usually converted to linear through rack and pinion sets, belts and pulleys, and other mechanical linkages. These are effective but limited systems. In contrast, integrated ...

For rotary or linear motors, motion is produced in the same way and the same basic physics and electromagnetic forces apply. The theory that produces "torque" in a rotary motor produces "force" in a ...

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 the next few weeks, linear motors will face their ultimate litmus test. After years in the eye of a swirling technical storm, surrounded by doubters who say they're too expensive, supported by a ...

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 ...

Stepper motor linear actuators (SMLAs) combine a stepper motor, precision lead screw and nut in one compact envelope, providing a highly configurable, customizable and robust system for linear motion.

Shape-memory alloys (SMAs) are those materials that respond to temperature changes by changing form factor. Originally funded by the U.S. Navy, SMA technologies were first commercialized by Raychem ...

Engineers demonstrate new developments for higher-force linear motion, rotary positioning, micrometer screw drives, tip/tilt ...
