The Basics of Voice Coil Motors (VCMs)

Voice coil motors, sometimes referred to as VCMs or voice coil actuators, are types of electric motors that generate force via the interaction between an electromagnetic coil and a permanent magnet. This concept has been widely employed in various applications where precise control of linear or angular positioning is required. VCMs find extensive usage in fields such as robotics, automotive systems, medical devices, and aerospace.

The working principle of a voice coil motor is relatively straightforward. When an electric current is passed through the coil, a magnetic field is generated. The interaction between this magnetic field and the fixed magnet results in a force that causes the coil to move. By regulating the magnitude and direction of the current, the motion of the voice coil can be accurately controlled, providing exceptional precision and control.
