If you can make a flex board where the coils are on little flaps (like those on a check valve or the flapper on your toilet), and you can get a long-wearing substrate (ex: a typical 250-300 page ...

Most electromagnetic actuators are rotating motors, or some variation on the theme, like servos. However, it’s possible to do linear actuation with electomagnetics, too. [Adrian Perez ...

The LAH24-67-000A linear voice-coil actuator features magnetic latches at each end of travel for critical applications where a specific “stop” position is desired when the coil ...

This compact voice coil actuator is designed for applications requiring precision control and fast speeds of response for military, aviation and space systems. Model RA54-18-000A is a rotary voice ...

Designed to save users time in determining the most suitable linear actuator, the company’s online VCA Calculation Tool calculates the optimum linear voice coil actuator size for a given ...

The company’s latest family of linear voice coil actuators provide increased safety and promise a long service life. The components feature two patented spring designs based on magnetic, rather ...

This video shows the working principle of the voice coil drives by Physik Instrumente (PI). Magnetic linear drives and voice coil actuators function based on the fact that the force acting on a ...

Details are at the shutter website and described in the paper Enhanced laser shutter using a hard disk drive voice-coil actuator, Rev. Sci. Instrum. 78 026101 (2007). The shutter, and variations based ...

A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications ...
