Moving Magnet Voice Coil Linear Actuator Introduction
Moving Magnet Voice Coil Linear Actuator is a type of electromechanical device that converts electrical energy into precise linear motion. It operates based on the principle of the Lorentz force, which states that a current-carrying conductor placed in a magnetic field experiences a force. Unlike traditional voice coil actuators where the coil moves and the magnet is stationary, in a moving magnet design, the magnet itself moves in response to the electromagnetic forces generated, while the coil remains stationary.
