Geeplus Voice Coil Actuators (VCAs) Upgrade Precision, Control in Medical Devices

Our Voice Coil Actuators helped to make Geeplus the worldwide leading supplier of actuators for ventilator applications.

The VM series of Voice Coils Motors addresses applications where excellent control characteristics for short stroke bidirectional linear actuation is required, e.g. in medical or optical equipment.

Voice Coil Actuators can develop force in either direction by reversing polarity of excitation. Also very important is the extremely low hysteresis, which is typically two orders of magnitude less than in proportional solenoids. This, along with the flat force characteristic exhibited by Voice Coil Actuators, lend them to applications requiring precise control of force and/or position: i.e. control valves, or lens and mirror positioning systems.

The very low hysteresis in one big advantage that Voice Coil Actuators have over proportional solenoids. This makes Voice Coil Actuators ideally suited for applications requiring well controllable bi-directional movement.
