A type of motor used to move the access arm of a disk drive in very small increments. Like the voice coil of a speaker, the amount of current determines the amount of movement. Voice coils replaced ...

Compared to the vast majority of systems that require motion control, medical devices typically tend to be smaller and lighter, simply because they are often portable/mobile systems that are ...

Your hard drive is silently monitoring its own health.

This video showcases PI’s Direct Drive Linear and Rotary Motors. The PI Linear Motors and Voice Coils are used for nano-meter level motion control, precision automation, and high-speed actuation. Air ...

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 ...

The linear voice coil motor (aka linear DC motor) is guided by a long-life plain bearing that can allow side loads up to 3 lb (13.5 N), while the precision ground 0.236-inch (6.0 mm) diameter shaft ...

The LVCM-010-013-01 linear voice coil motor is 0.375 in. (9.5 mm) in diameter and the length at mid-stroke is 0.81 in. (20.7 mm) long. This miniature voice coil motor has a high force-to-size ratio ...

The number of areas that can benefit from VCA technology are constantly expanding as engineers use VCAs to address complex, delicate, or sensitive motion applications The number of areas that can ...

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 application.
