Original Press Release:

Voice Coil Actuators Used in Ventilators Available in 4 Weeks from Receipt of Order!

Santa Clarita, CA -- H2W Technologies have been manufacturing voice coils that have been custom designed for the medical industry. Voice Coil Actuators in quantities of 100 to 200 are available in 4 weeks and OEM (Original Equipment Manufacturers) quantities can be available in 6 to 8 weeks from receipt of order! Voice coils have been desirable for applications such as ventilators because of their compact design and high-speed capabilities coupled with their sliding contact bearing system, which allows for high lifetime, high cycle, and a desirable MTBF in the system.

The actuator utilizes a unique electromagnetic circuit design. This design allows for a motors with minimal cross section diameter of up to 1.20 inches [30.5 mm], and strokes up to 0.60 in. [15.2 mm] stroke; this size generates up to 1.12 lbs [5.0 N] of continuous force and 3.36 lbs [15 N] of peak force. Each actuator is guided by sliding contact bushing assemblies. Voice coil actuators are ideal for applications that require quick, short moves with fast settling times.
