Toroidal shuttle winders
For laying wire onto a closed core with pitch and tension control. This is the machine that makes toroidal work possible.
Toroidal Winding is the toroidal winding shop of Antonio Perin, in Carate Brianza, Italy. It exists to do one thing well: put copper on a toroidal core the way the customer needs it.
A toroidal transformer is made by hand more than it looks. The machine lays the wire, but the turns count, the order of the layers, where the shield runs and how the lead comes out stay decisions of the person building it.
A large organisation loses time on that. It has to open a job, route the drawing, wait for a machine slot. The result is that special parts, the twenty piece ones, become a problem to postpone.
Here the opposite happens. Minimum quantity is one piece, the sample is made within the week, and the person answering the phone is the person winding. That is why customers who arrive for a prototype stay for the run.

Dielectric strength test, insulation measurement, turns ratio, no load current and ohmic resistance.
Resin treatment to lock the turns, improve heat transfer and take out the mechanical hum.
Taping, flying lead or faston terminations, potting, marking and packing.
If a constraint does not add up we say so immediately, even when that means proposing a different part from the one requested.
The prototype is built and tested by the same method as production. So what you test is what you receive.
Test values from the sample go into the data sheet and stay traceable by batch.
Carate Brianza, province of Monza e Brianza. Thirty kilometres from Milan, inside the district that supplies machines and components to half of Europe.
If you are nearby and the part is complex, half an hour in the workshop is worth three email exchanges.
