A voice coil actuator (VCA) is a type of electromagnetic actuator that converts electrical energy into mechanical motion. It consists of a coil of wire, known as the voice coil, which is placed within a magnetic field generated by permanent magnets. The interaction between the magnetic field and the current flowing through the voice coil produces a force that drives the actuator’s motion.

The magnets used in a voice coil actuator play a crucial role in its operation. They provide the magnetic field necessary for the actuator to function effectively. There are two main types of magnets commonly used in VCAs: permanent magnets and electromagnets.  Rectangular NdFeB Rare Earth Linear Resonance Actuator LRA Magnets N35AH

Permanent magnets are made from materials with naturally occurring magnetic properties, such as neodymium (NdFeB) or samarium cobalt (SmCo). These magnets are known for their high magnetic strength and stability. Permanent magnets are typically used in VCAs where a constant magnetic field is required.  N38SH Micro NdFeB Magnet for Voice Coil Actuators (VCAs)

Electromagnets, on the other hand, are created by passing an electric current through a coil of wire, which generates a magnetic field. The strength of the magnetic field can be controlled by varying the current flowing through the coil. Electromagnets offer the advantage of adjustability, allowing for fine-tuning of the actuator’s performance.
