44.8mm Long Stroke Micro Cylindrical Voice Coil Motor For Scanning Systems

The SUPT NOTION VCAR0022-0448-00A is a long-stroke cylindrical voice coil motor that delivers a peak thrust of 22 N over a stroke range of up to 44.8 mm. This actuator is specifically designed for scanning systems, optical delay lines, and precision linear stages that require long strokes without the need for complex rotary-to-linear conversions.

This voice coil motor delivers a continuous thrust of 11.4 N at 25°C, meeting the demands of continuous scanning or reciprocating motion. A back-EMF constant of 4 V/m/s ensures excellent speed feedback linearity. The voice coil weighs 52 g, and the motor’s maximum operating voltage is only 14.3 V, making it easy to drive with standard amplifiers.

Overall dimensions: stator diameter 48 mm, length 75.7 mm.

In optical coherence tomography (OCT) or laser scanning systems, linear actuators with long stroke and smooth motion are critical. This model of voice coil motor provides direct, backlash-free motion without the need for lead screws or belts. This results in higher scan linearity and reduced mechanical noise.

This motor is also ideal for precision gauges and measurement systems, where probes must travel up to 44.8 mm to measure part features. The direct-drive design ensures zero backlash, thereby improving measurement repeatability. In active suspension or seat vibration cancellation systems, the 22 N thrust can counteract low-frequency disturbances in heavier systems.
