Inner Stator Needle Winding Machine
Needle winder for inner-rotor stators with narrow slot openings, for appliance, pump and automotive motors.
Built around your stator drawing
Inner-rotor stators have teeth pointing inward, so the needle must travel inside the bore and pass through narrow slot openings. The machine combines a stroke axis, rotation axis and fine oscillation to wind concentrated coils with high slot fill while protecting the enamel.
Key features
- Slim needles for slot openings down to 1.5 mm
- Programmable wire path for high slot fill
- Enamel-friendly nozzle design and wire guides
- Automatic hook-and-cut for lead wires
- Fixture change in under 15 minutes
- Production and alarm logs on HMI
