C12204-001 Mini All-Metal Coreless Servo (PWM)

The C12204-001 packs a coreless brushed motor and a full metal gear train into a
23 x 12 x 27.5 mm housing. At 8.4 V it delivers 5.3 kg·cm while holding
0.07 s/60° — a power density that suits tight installations where a standard
micro servo runs out of headroom.

This PWM variant is driven by a standard RC pulse (1000-2000 us at 50 Hz), so it
drops straight into any receiver or flight controller without extra firmware work.

Typical uses: control surfaces on fixed-wing models and helicopter linkages,
steering on RC cars, joints on desktop robots and small quadrupeds, finger joints
in dexterous hands, pan/tilt on compact camera gimbals, and robotics teaching kits.

Features

• Coreless brushed motor — no iron core in the rotor, so inertia stays low
  and start/stop response is quick. Service life is well beyond a comparable
  cored motor.
• Compact envelope, high output — 23 x 12 x 27.5 mm, 21 g, up to 5.3 kg·cm.
• Full metal gear train and case — machined metal gears resist wear; the
  metal shell helps dissipate heat and adds rigidity under shock loads.
• Tight backlash — precision-cut gears keep positioning repeatable over a
  long service life.
• Wide input range — 3.6 V to 10 V, so a 1S or 2S LiPo can drive it directly.
