H2W Technologies Offers Voice Coil Actuators for Ventilators

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.
