• Body length: 26 mm
• Torque (max efficiency): up to 170.8 g·cm (model dependent)

Target Applications & Solutions
With an outer-rotor design and compact profile, RB-3626-68 offers higher rotational inertia and torque density than similar-size inner-rotor units, enabling stable, low-noise drive in tight spaces. Typical integrations include:

• Financial & Office Automation: ATMs, vending machines, printers, projectors — precise motion in compact housings.
• Medical & Personal Care: Micro pumps, electric valves, massagers, electric shavers — reduced vibration and noise.
