Electric motor windings for machine tools: outstanding performance for precision mechanics
Modern machine tools such as automatic lathes, CNC machining centers and high speed milling machines demand exceptional levels of precision, repeatability and reliability from their electric motors. At the core of these performance requirements are the motor windings, which play a crucial role in ensuring stable motor operation and consistent production quality.
Key technical requirements for electric motor electric motor windings in machine tools
In high-intensity operating environments involving frequent starts and stops, sudden load variations and micron-level machining, windings must meet the following requirements:
- be perfectly balanced to minimize vibration;
- remain thermally stable to resist localized overheating;
- be custom designed based on machine configuration and application type.
Zampolli Avvolgimenti applies its proven expertise in high-performance spindle windings to the development of motor windings for advanced machine tools, with one clear objective, to guarantee uninterrupted, high-precision production.
Materials and technologies that enhance winding durability for machine tools
The thermal and mechanical stresses placed on machine tool motors demand careful selection of materials and construction methods.
At Zampolli Avvolgimenti, we use:
- high-conductivity enameled copper wire;
- class F or H thermal insulation, ensuring long-lasting performance even under high thermal loads;
- thermosetting impregnation resins applied through immersion systems, improving both dielectric strength and mechanical adhesion;
- manual coil insertion, allowing precise control of tolerances and uniform placement within the stator stack.
Every aspect of our process is designed to deliver high-performance windings that withstand even the most demanding operating conditions over time.
Where Avvolgimenti Zampolli are used in industrial machine tools
Our windings are employed in electric motors across a wide range of industrial machine tools, including:
- CNC machining centers for high-precision metalworking;
