Semi-Automatic Toroidal Coil Winding Machine for Magnetic Ring Cores WM-9319

›

The WM-9319 winds magnet wire onto closed toroidal (ring) cores — the ring-core inductors, common-mode chokes, current transformers and small toroidal transformers that go inside a power supply, not onto finished cable. It takes wire from 0.05 to 0.25 mm, cores from 13 × 7 × 4 mm up to 20 × 16 × 7.5 mm, and 50 to 3,000 turns per program, with 1,000 job memories on an English-labelled controller. Wire storage rings of 2.0 to 6.0 mm width are interchangeable on the same machine, trading wire capacity against the smallest core hole the shuttle can pass through.

Specifications

Key features

• Winds closed ring cores without cutting them — wire is pre-loaded onto a split storage ring that passes through the core hole and lays turn after turn around the ring
• Storage rings are interchangeable from 2.0 to 6.0 mm width, so one machine covers several core sizes: a wider ring carries more wire, a narrower ring threads a smaller inner hole
• Steady, low pulling force built for 0.05 – 0.25 mm magnet wire — thin enamel is not stretched or scraped at winding speed
• English-labelled controller with step programming, turns, pitch, winding direction and quantity, plus 1,000 stored job memories for repeat orders
• Takes enamelled copper and aluminium wire as well as steel and nylon filament, so the same head covers coil work outside pure copper windings
• Free sample test — send your cores and wire, we wind them on this machine and send you the video before you order

What it processes

• Toroidal inductors and common-mode chokes on ferrite or iron-powder ring cores within the 13 × 7 × 4 mm to 20 × 16 × 7.5 mm size range
• Primary and secondary windings of small toroidal transformers, and primary windings on larger toroidal transformers
• Current transformers, relay coils, resistance coils and similar small ring-core windings
• High turn-count coils in fine magnet wire (up to 3,000 turns) where hand winding is too slow and too inconsistent

Suited for: magnetic component production — winding 0.05–0.25 mm magnet wire onto closed ring cores from 13 × 7 × 4 mm to 20 × 16 × 7.5 mm, 50 to 3,000 turns per coil.

Not suited for: finished cable, power cords or extension leads. This is a component winder for transformer and inductor shops, not a cable coiler — the coil it produces is the part, not a packaged length of cable. If what you actually need is to measure, coil and tie finished cable, use the WM-4810 automatic wire coiling machine with meter counter for wire Ø0.5–16 mm, or browse the rest of the coil winding and binding machines.

Where it does fit next to our other machines: for the coils that mount on a spindle rather than thread through a core — bobbins, tube formers and mandrels in 0.05–0.8 mm wire, up to a 420 mm winding width — see the WM-9324 automatic magnet wire coil winding machine. And once a coil is wound, many magnetic-component makers tape-wrap it before assembly. That step is the WM-470 transformer coil tape winding machine, which wraps transformer coils, magnetic core coils, relay and resistance coils at 46 pcs/min — check your finished coil against its 25–85 mm two-axis tape range before pairing the two.
