9025MG Metal Gear Servo

The 9025MG is a lightweight micro digital servo engineered with solid copper gears and a responsive coreless motor. It delivers reliable stall torque up to 1.5kgf·cm at 6V while eliminating the gear stripping common in standard plastic-gear micro servos. This makes it an excellent choice for students, makers, and hobbyists building robotic mechanisms, pan-tilt mounts, and RC models.

Durable copper gear construction

Solid internal copper gears provide enhanced wear resistance and impact protection under high mechanical loads. This all-metal gear train prevents stripped teeth and significantly prolongs operating lifespan compared to conventional 9g plastic servos.

Coreless motor and digital precision

Powered by a coreless motor and digital control circuitry, the servo achieves no-load transit speeds down to 0.11 seconds per 60 degrees at 6.0V. A tight dead band of 3μs or less combined with an angle deviation within 1 degree ensures rapid response and accurate holding positions.

Compact form factor and dimensions

Weighing just 13.5g with an ABS housing, the servo is designed for easy integration into tight, space-constrained assemblies. Its compact footprint makes it practical for miniature linkages and weight-sensitive builds.

Plug-and-play hardware compatibility

The integrated 245mm cable features a standard JR connector that interfaces directly with Arduino boards, expansion shields, and RC receivers. It operates across a 4.8V to 6.0V DC supply and responds to standard 500 to 2500μs PWM control signals without extra wiring.

Versatile robotics and DIY applications

With a 210-degree mechanical limit and 1.5kgf·cm stall torque at 6V, this servo is well suited for desktop robotic arm joints, hexapod walkers, and sensor pan-tilt mechanisms. It also provides dependable actuation for RC steering linkages, throttle controls, and smart home automation projects.
