Description

Moving Magnet Voice Coil Linear Actuator Introduction

Moving Magnet Voice Coil Linear Actuator is a type of electromagnetic actuator designed for linear motion. It combines the principles of a moving magnet system and a voice coil actuator to generate linear movement.

In this design, a permanent magnet is typically attached to the moving part of the actuator. This magnet moves along the axis of motion. The actuator also incorporates a coil of wire (the voice coil) that is stationary or attached to the stationary part of the system. When an electric current is applied to the voice coil, it interacts with the magnetic field produced by the moving magnet. This interaction generates a force that causes linear motion along the axis of the actuator. The linear motion is typically precise and controllable, making Moving Magnet Voice Coil Linear Actuators suitable for applications where accurate positioning or linear displacement is required.
