1555 Specifics

A key advantage of a moving magnet voice coil actuator is that they are very reliable and durable. This is, in comparison to moving coil Actuators, due to the lack of moving wires. Compared to other electric actuators motors with gearboxes, they can accelerate quickly and then come to a gentle stop at a very precise point.

The voice coil actuator can support high positioning resolutions -in combination with external position sensors and motion controllers. They enable reduced system cost, control complexity and improve robustness.
