AC Motor windings: handcrafted excellence, certified materials, and reliable performance <\/strong>
<\/h2>\n\n\n\n
<\/div>\n\n\n\n

Avvolgimenti Zampolli <\/strong>specialises in the prototyping and production of AC electric motor windings, with a specialization in three-phase systems. This dedicated expertise allows us to deliver highly customized solutions and top-level technical precision for complex industrial applications. All of our resources and technical know-how are concentrated on AC systems, which today set the standard<\/strong> for reliability, energy efficiency, and long-term durability.<\/p>\n\n\n\n

What sets us apart is not only the quality of our materials<\/strong>, including high-conductivity enamelled copper wire and Class F and H thermal insulation systems, but also the accuracy of our winding techniques. This precision is essential to ensuring maximum performance and full compliance with international standards.<\/p>\n\n\n\n

Custom electric motor windings for reliability and optimized performance <\/strong><\/strong><\/h2>\n\n\n\n
<\/div>\n\n\n\n
\n

Zampolli\u2019s three-phase windings<\/strong> are engineered for high performance, long service life, and optimised energy efficiency,even in demanding operating conditions. <\/p>\n\n\n\n

In addition to our standard windings, we manufacture fully customised solutions<\/a><\/strong> for motors with non-standard requirements, such as harsh environments, unusual speeds, unconventional working conditions, and prototype or research-driven applications.<\/p>\n\n\n\n

Each special project is handled with the utmost care, from initial design through to final testing, to ensure a solution that\u2019s fully aligned with the customer\u2019s operational needs.<\/strong><\/p>\n<\/div><\/div>\n\n\n\n

<\/div>\n\n\n\n

Our method for manufacturing electric motor windings <\/strong><\/strong><\/strong><\/h2>\n<\/div>\n<\/div>\n\n\n\n

At Avvolgimenti Zampolli, our winding production <\/strong>process follows a series of carefully controlled steps designed to ensure the highest standards of quality and reliability:<\/p>\n\n\n\n

\n
\n

RIGOROUS INSPECTION OF RAW MATERIALS <\/strong><\/h4>\n\n\n\n

a fundamental step to guarantee winding quality from the start.<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Electric<\/figure>\n<\/div><\/div>\n\n\n\n
\n

STATOR CORE INSULATION <\/strong><\/h4>\n\n\n\n

applied manually or mechanically depending on stator size. This crucial process protects the winding from potential faults. <\/p>\n\n\n\n

We maintain a stock of pre-insulated stator cores to enable rapid response to urgent orders.<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Electric<\/figure>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
\n
\n

COPPER COIL PRODUCTION <\/h4>\n\n\n\n

carried out on specialised machines customised to the required coil dimensions. All coil winders are PLC-controlled to accurately store programmes and tooling settings, thereby minimising operator error. <\/p>\n\n\n\n

Rigorous quality checks are performed on incoming copper wire and during the initial production cycles. End-of-wire sensors automatically halt the machine to maintain coil integrity.<\/p>\n\n\n\n

\"Electric<\/figure>\n<\/div><\/div>\n\n\n\n
\n

INSERTION OF COILS INTO THE STATOR<\/strong><\/strong><\/strong><\/h4>\n\n\n\n

a delicate process still predominantly performed by hand (around 70% of our production). This manual method ensures high precision and flexibility, especially for specialised motors, with each coil carefully positioned to meet exact design specifications.<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

<\/p>\n\n\n\n

\"Electric<\/figure>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n
\n
\n

ELECTRICAL CONNECTIONS <\/h4>\n\n\n\n

Made using thermal compression machines for conductor sections up to 70 mm\u00b2. For larger sections or specific customer requests, traditional flame soldering is used.<\/p>\n\n\n\n

<\/div>\n\n\n\n
\"Electric<\/figure>\n<\/div><\/div>\n\n\n\n
\n

LASHING AND COIL HEAD FORMING<\/strong><\/h4>\n\n\n\n

Performed either manually or mechanically, depending on winding size and client requirements.<\/p>\n\n\n\n

\"Electric<\/figure>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n

Every winding undergoes 100% end-of-line electrical testing (EOL)<\/strong> to verify full functionality before the final stage. The last step is impregnation and curing<\/strong>: windings are impregnated with water-based varnish or resin and then oven-cured. This treatment provides excellent mechanical, chemical, and dielectric resistance.  <\/p>\n\n\n\n

Each stage of our process is vital to delivering electric motor windings that are efficient, reliable, and built to last.<\/p>\n\n\n\n

<\/div>\n\n\n\n

The value of handcrafted electric windings <\/strong><\/h2>\n\n\n\n
<\/div>\n\n\n\n

Manual production of electric motor windings remains a benchmark of quality, <\/strong>especially for applications requiring maximum reliability and precision<\/strong>. Unlike automated methods, the artisanal approach enables each winding to be precisely tailored to the motor\u2019s geometric and functional requirements, compensating for manufacturing tolerances and optimising coil placement within the stator slots.
<\/p>\n\n\n\n

At Avvolgimenti Zampolli,<\/strong> highly skilled technicians<\/strong> insert coils by hand. This hands-on expertise provides a clear advantage<\/strong>: manually inserted windings withstand  thermal stress, mechanical vibration, and frequent start-stop cycles, ensuring consistent peak performance even in the most demanding conditions.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Premium materials for high-efficiency motor windings <\/h2>\n\n\n\n
<\/div>\n\n\n\n

To guarantee the performance and reliability of our windings<\/strong>, we use only top-quality materials. This includes high-conductivity enamelled copper wire<\/strong> and Class F or H insulation systems<\/strong>, designed to withstand high thermal and electrical stress.<\/p>\n\n\n\n

All production stages are subject to rigorous quality checks, ensuring safe, long-lasting, and efficient windings for demanding industrial applications.<\/p>\n\n\n\n
