FEETECH FT90B Servo Motor
FEETECH FT90B Servo Motor
The FT-90B-C001 is a high-speed micro 6V 1.5kg-class digital servo powered by an efficient metal brush motor and enclosed in a lightweight, durable PC plastic case. Engineered for responsive and agile motion control, it features reliable plastic gears, a 21T (4.86) horn gear spline, and tough plastic/POM horns. Operating within a 3–6V voltage range, this digital servo delivers a peak stall torque of 1.5kg.cm and a rated torque of 0.5kg.cm at 6V, while reaching a rapid no-load speed of 110RPM at 6V. It supports a precise 180° running degree under standard 500–2500 µsec pulse width signals, alongside a 180° mechanical limit angle. Weighing a mere 10.5g with a 250mm±5mm (JR) connector wire featuring brown, red, and orange leads, it offers an outstanding power-to-weight profile for compact smart robotics, educational electronics, and micro RC aircraft builds.
Common use cases: Micro RC aircraft control surfaces (aileron, elevator, rudder), educational robot kits, small fixed-wing drone steering, lightweight tabletop robot joints, and entry-level RC models where minimal weight and low cost are the primary requirements.
