In applications requiring ultra-precise motion control, such as optical alignment, semiconductor testing, and medical imaging, linear coil actuators—commonly known as voice coil actuators—are indispensable. DH-Robotics specializes in designing these actuators to deliver high-speed, zero-backlash movement with exceptional repeatability, addressing the needs of industries where micron-level accuracy is non-negotiable.
High-Resolution Motion for Critical Applications
DH-Robotics’ voice coil actuators utilize a direct-drive mechanism and non-commutated design, eliminating cogging and hysteresis that plague traditional actuators. This results in smooth, continuous motion with resolutions down to 0.1 microns, ideal for tasks like laser beam steering or lens positioning in microscopy. For example, a leading optics manufacturer integrated their actuators into their autofocus systems, achieving a 50% reduction in focus time while maintaining ±0.5-micron accuracy. Such precision ensures consistent performance in high-stakes environments.
Compact Design for Space-Constrained Systems
Recognizing the need for miniaturization in modern equipment, DH-Robotics offers compact voice coil actuators with high force-to-size ratios. Their miniature series, with strokes up to 10mm and peak forces exceeding 30N, fits into tight spaces without compromising output. A medical device company leveraged this design to develop a portable ultrasound probe, where the actuator’s small footprint and low heat generation enabled prolonged battery-powered operation. This adaptability makes their solutions suitable for handheld tools and embedded systems.
Precision Actuators: Ultra-Accurate Motion Control
DH-Robotics’ voice coil actuators redefine precision motion control by combining sub-micron accuracy, compact engineering, and modular feedback options. As industries push the boundaries of miniaturization and speed, their linear coil actuators provide a reliable foundation for innovation. For businesses seeking actuators that enhance performance in optical, medical, or semiconductor applications, they deliver solutions that meet—and exceed—the most demanding requirements.
