Cambridge Technology 6220HZBR Galvanometer Motor

The Cambridge Technology 6220HZBR Galvanometer Motor is a high‑speed, closed‑loop single‑axis optical scanner built on Cambridge Technology’s 62xxH moving‑magnet platform. It ships with a Y‑axis mirror kit for immediate use in Cambridge Technology optical systems, typically laser scanning, laser projection, or precision measurement setups. Key specifications include a 40° maximum scan angle, rotor inertia 0.125 gm·cm² (±10%), torque constant 6.17×10⁴ dyne·cm/A (±10%), rotor‑to‑case thermal resistance 1.0 °C/W, coil resistance 2.79 Ω and inductance 180 μH, back‑EMF 108 μV/°/s (±10%), RMS drive current up to 3.9 A and peak current up to 20 A. The typical small‑angle step response is about 200 μs, and the unit weighs 42.5 g. The included mirror set is the standard 6M2205S‑S, designed for Y‑axis scanning in Cambridge Technology scanners. When paired with Cambridge Technology drives and control electronics, the 6220HZBR delivers repeatable angular displacement with stable thermal performance, narrowing tolerance for high‑speed positioning tasks and compact optical benches.
