Outer Stator Needle Winding Machine
Servo needle winder for external-rotor BLDC stators used in ceiling fans, hub motors and cooler fans.
Representative imageBuilt around your stator drawing
External-rotor stators have open slots facing outward, which lets a needle lay each turn directly into the slot. This machine indexes the stator tooth by tooth, winds all three phases in one clamping and parks the start and finish leads on the terminal pins, ready for lacing or termination.
Key features
- Servo needle stroke, index and oscillation axes for precise turn placement
- Closed-loop wire tensioner keeps phase resistance consistent
- Winds 3-phase star or delta patterns without re-clamping
- Quick-change mandrels for different stator OD and stack heights
- Automatic lead parking and wire cutting
- Turn counting and wire-break detection with alarm
