In some applications, deploying a pair of moving coil rotary voice coil actuators may be preferable. Each actuator can deliver strokes of up to 15° in either a clockwise or counter-clockwise direction ...

Specifically, linear voice coil actuators can be designed to meet the precise motion control requirements and ultra-small size needed in the medical industry. These miniature VCAs are commonly ...

Figure 1. Linear Voice Coil Actuator. Used in a wide range of medical and industrial applications, an axial voice coil actuator is composed of a permanent magnet within a moving tubular coil of wire, ...

The growing field of human-robot interaction (HRI) demands robots that move fluidly, gracefully, compliantly and safely. This paper describes our recent work in the design and evaluation of ...

A high performance voice-coil driven nanopositioning slide for high speed precision laser processing and surface metrology applications in industrial automation. Applications of fast focus motor ...

Ergo, the loudspeakers in those radios derived their magnetic fields for their voice coils from electromagnets, which were called “field coils.” The DC excitation of a field coil would come from using ...

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 ...
