2312 Frameless Outer Rotor BLDC Motor 22mm 12V
Rotor and stator supplied without housing so they drop straight into your gimbal or robot axis, with 12 slot winding tuned for torque or smoothness.

Why buyers choose this motor
1
Integrates into your own housing
No can and no end caps means the stator and magnet ring mount directly on your shaft and housing, cutting stack height and removing a bearing pair from the chain.
2
Torque or smoothness, your choice
Winding and magnet grade are selected per project, so the same 12 slot platform can favour holding torque for a robot joint or low cogging for a camera axis.
3
Matched to your assembly drawing
Shaft, mounting features and lead routing are produced to your integration drawing, with polar difference held within 1.0 Ohm for balanced phase current.

Customization options built into the tooling
- Frameless rotor and stator dimensions matched to your housing bore and stack height
- Winding and magnet grade selected for holding torque or low cogging priority
- Custom shaft length, D-cut and bearing seat per integration drawing
- Integrated PWM driver or bare phase leads, whichever suits your controller
- Lead wire routing, length and connector to match your harness
- Sample sets supplied for fit testing before tooling is released
Typical applications
Gimbal and pan-tilt axes, robot joints and end effectors, drone actuator mounts, camera sliders and compact direct drive stages that need a motor inside their own structure.
