Voice Coil Actuator in Ventilators play a critical role in controlling the flow of air and gases precisely and reliably, directly impacting the ventilator ability to provide life-sustaining breathing support to patients. VCAs are electromechanical devices that convert electrical energy into linear motion. They are named for their operational similarity to the voice coils in loudspeakers.
