This paper will discuss a variety of rotary position feedback sensors including digital, contacting analog, and non-contacting analog, and may act as a high- level guide to selecting the right sensor ...

They are installed not only in electrical linear motors, but also in pneumatic, hydraulic, ball-screw or power-grip belt drives and wherever high-accuracy, dynamic positioning tasks must be performed.

A linear actuator combines linear-motion components and a linear shaft motor (direct drive) in one assembly. Such an actuator creates motion in a straight line, in contrast to the circular motion of a ...

This video shows the working mechanism of Physik Instrumente (PI)’s Hybrid Stage. PI offers a unique hybrid concept with parent position measurement and closed-loop control. Some of the key features ...

Subsea environments are one of the most difficult areas for any sensor to perform, especially when performance life of as much as 20 years is expected in an underwater application. In subsea ...

Building a successful linear motion system starts with choosing the appropriate actuator. Between the different sizes, technologies, and qualities, hundreds of options exist. The trick is to winnow ...

RC servos are a common component in many robotics projects, but [Giovanni Leal] needed linear motion instead of the rotary actuation that servos normally offer. The 3D Printed Mini Linear Actuator was ...

This video is an animation of the principle behind PI’s magnetic linear motors. The magnetic linear motors correspond to a sequence of a number of voice-coil actuators; individual coils can be ...
