The voice coil motor is the simplest type of electric motor, consisting of only a magnetic housing and coil. Its simple, customizable design comes with many advantages, including a high power to mass ratio, high acceleration, low to no hysteresis and zero cogging. due to their small size, they used for smaller, precise applications such as focusing, oscillatory systems and mirror tilting.
Akribis Systems offers three series of high-performance voice coil motors covering a range of sizes and force densities.
The AVM Series is our standard voice coil motor. This permanent-magnet direct drive actuator operates without backlash and cogging.
