Linear actuators are used for machine tools and similar devices because they can exhibit high speed, high acceleration/deceleration, and high-precision positioning. In particular, coreless type linear actuators have a small thrust compared to linear actuators having a core, but because they do not generate cogging their fluctuation in thrust is small. Utilizing this characteristic, they are used in environments requiring high-precision positioning such as head drives for electronic component mounting machines and for very fine movements when precision is needed.

Linear actuators are used in machine tools because of their high-speed performance, high acceleration and deceleration, and accurate positioning. There are coreless types of linear actuators, as well. They generally have a smaller thrust force than core linear actuators, but they do not produce cogging, ...

A loudspeaker produces sound when the voice coil makes the vibrator vibrate. The general requirement of the loudspeaker is to produce uniform sound over a wide range of the frequencies.
Lorentz force is generated in the coil when the magnetic field of a permanent magnet...
