BYWDD-330-140
High precision potential: DD motors generally integrate high-resolution encoders, with absolute encoders reaching 23 bits or more. Full closed-loop control provides repeatability of ±1-2 arcsec, difficult to maintain with conventional servo-and-reducer systems because of backlash and wear. High stiffness and rapid response: mounting the load directly on the rotor shortens transmission and increases servo stiffness. Millisecond settling reduces waiting during frequent starts, stops, and rapid positioning in wafer inspection or sorting. Smooth low-speed motion without stick-slip: low-speed scanning or fine adjustment has less velocity fluctuation and better positional stability than geared servo systems. Compact and low maintenance: no wear-prone belts or gears, virtually no routine maintenance, and a large hollow bore simplifies cabling and layout. Resolution row: the unit field reads absolute boss-c protocol; the value field is empty.

Electro-optic deflectors (EODs) are optical devices used to steer or deflect light beams by applying an electric field to a specialized optical crystal. Unlike mechanical beam steering systems that rely on moving mirrors, electro-optic deflectors enable high-speed, non-mechanical beam control with exceptional precision and responsiveness. They are widely used in laser scanning, optical communications, microscopy, laser printing, spectroscopy, and scientific research, where rapid and accurate laser beam positioning is essential.
