Voice Coil Actuators

¡¡

Voice coil actuators are two wire non-commutated direct-drive, hysteresis-free, cog-free devices used for providing highly accurate linear and rotary motion. By virute of their high acceleration and the absence of commutation, they offer numerous advantages in semi-conductor applications. They deliver infinite position sensitivity, limited only by the encoder used for feedback. The force-versus-stroke curve is perfectly smooth. It all adds up to increased throughput for your system.
