Description

Moving Magnet Voice Coil Linear Actuator Introduction

Moving Magnet Voice Coil Linear Actuator is a specialized electromagnetic device crafted for linear motion. By seamlessly merging the principles of a moving magnet system and a voice coil actuator, this mechanism excels at generating precise linear movement. In this design, a permanent magnet is strategically affixed to the mobile component of the actuator, traversing along the axis of motion. Simultaneously, the actuator integrates a stationary coil of wire, known as the voice coil, which is either affixed to or part of the stationary portion of the system. When an electric current courses through the voice coil, it engages with the magnetic field generated by the moving magnet. This interaction yields a force that propels controlled linear motion along the axis of the actuator.
