FEETECH FT-3325 Servo Motor
FEETECH FT-3325 Servo Motor
The Feetech FT3325 Series (FT3325M & FT3325P) consists of high-performance 6V–8.4V 7kg.cm class digital servos designed with core motors, durable metal gears, ball bearings, and 25T output shafts. While sharing a 6–8.4V operating voltage range and pulse width modification via a digital comparator, they feature distinct structural and performance configurations. The FT3325M is housed in a premium aluminium case (28.5±1g), delivering a 9.5kg.cm peak stall torque and 0.095sec/60° (105RPM) high speed at 8.4V, with a 250° running degree (500–2500 µsec). Conversely, the lightweight FT3325P features an ABS case (26.2±1g), offering a 5.8kg.cm peak torque and 0.133sec/60° speed at 6V, with a 120° running degree (900–2100 µsec) and an ultra-narrow 2 µsec dead band. Both digital servos operate without mechanical limit angles, providing versatile, precise control options for robotics and automation.
