Al diseñar motores eléctricos o transformadores, choosing the right tipo de bobinado is essential for overall performance. The two common types—bobinado concentrado y bobinado distribuido—may seem like simple coil arrangements, but they can significantly affect machine operation and efficiency.
The choice between bobinado concentrado y bobinado distribuido influences key factors such as eficiencia, disipación de calor, suavidad del par, ruido electromagnético, y costo de fabricación. Engineers carefully select the right Diseño de bobinado de motor based on application requirements, especially in areas like vehículos eléctricos, Robótica, turbinas de viento, y electrónica de consumo.
To better understand these differences, this article explains how each tipo de bobinado works, their main advantages, and how to choose the right solution for your application—whether the priority is compact design, higher performance, or cost control.
Concentrated Winding Design
Bobinado concentrado es un Diseño de bobinado de motor where each coil is wound around a single stator tooth rather than distributed across multiple slots. This structure creates a more compact layout, while reducing the number of turns and shortening the copper path.
With less wire required, pérdidas de cobre can be reduced, helping improve eficiencia del motor in space-limited applications such as patinetes eléctricos, drones, y herramientas portátiles. This makes bobinado concentrado a suitable option for compact electric motor designs where size and performance are important.
However, this simpler winding structure also involves some trade-offs. Bobinado concentrado typically produces a trapezoidal back EMF waveform and higher torque ripple, which may lead to increased vibration and noise in applications that require smooth operation.
For designs that prioritize alta densidad de potencia y lower manufacturing cost, concentrated winding remains a practical choice.
Bobinado distribuido
En bobinado distribuido, coils are placed across multiple stator slots or teeth instead of being concentrated on a single tooth. This Diseño de bobinado de motor creates a more uniform magnetic field, helping improve the overall performance of motor electrico y transformadores.
One of the key advantages of bobinado distribuido is its ability to produce a sinusoidal back EMF, resulting in a smoother voltage waveform with fewer armonía. This helps achieve quieter motor operation, mejorado suavidad del par, and reduced vibración, making it suitable for applications such as Vehículos eléctricos, Sistemas HVAC, y automatización industrial.

Uso y pérdidas de cobre
Bobinado concentrado generally uses less cobre because the coils are shorter and wound around a single stator tooth. This helps reduce resistive losses and lower manufacturing costs. In comparison, bobinado distribuido requires longer coil paths, which can increase copper usage and slightly raise losses.
Forma de onda de fuerza contraelectromotriz
Bobinado concentrado generates a trapezoidal back EMF waveform, which can create more harmonics due to its sharper waveform changes. In contrast, bobinado distribuido produces a forma de onda sinusoidal, providing smoother power output and more efficient motor operation.
Contenido armónico
Ondulación de par
Con bobinado concentrado, the magnetic field distribution is less uniform, which can result in higher torque ripple and may not be ideal for precision applications. Bobinado distribuido provides smoother par de salida, making it a better choice for systems that require stable operation, such as EV motors y Robótica.
Gestión Térmica
Bobinado distribuido provides better disipación de calor because the windings are distributed across multiple slots, allowing heat to spread more evenly. In comparison, bobinado concentrado generates heat in a smaller area, which may require additional cooling solutions.
Complejidad de fabricación
Bobinado concentrado features a simpler structure and is easier to automate, making it suitable for producción en masa. Bobinado distribuido requires a more complex manufacturing process, but it provides performance advantages para high‑efficiency motor designs.
Aplicaciones
Bobinado concentrado is suitable for compact and cost‑sensitive designs, como small appliances y budget‑friendly motors. Bobinado distribuido se utiliza comúnmente en high‑performance motor systems, incluido vehículos eléctricos, Accionamientos industriales, y precision automation equipment.
Cómo elegir el tipo de bobinado adecuado
Al elegir entre bobinado concentrado y bobinado distribuido, the key is to balance eficiencia, costo, actuación, y space requirements.
If you’re designing pequeños motores or targeting producción en masa rentable, bobinado concentrado can be a practical choice. It uses less copper, simplifies assembly, and keeps the motor compact. By contrast, if you prioritize smooth torque, armónicos inferiores, y mayor eficiencia, bobinado distribuido can offer better performance, especially in Vehículos eléctricos, Accionamientos industriales, y electrodomésticos de primera calidad.
Meanwhile, emerging technologies are combining advantages from both approaches. Fractional‑slot concentrated windings are being used in axial‑flux motors and next‑generation Aplicaciones de vehículos eléctricos, offering high torque density in compact designs.
Elegir lo correcto winding approach isn’t simply about tradition—it’s about understanding your system’s requirements and selecting the diseño de bobinado that best fits your application.
Conclusión
Entendiendo la diferencia entre bobinado concentrado y bobinado distribuido can help you choose a motor or transformer design that balances size, efficiency, and performance. Each winding type has its own advantages, so the right choice depends on your application’s specific requirements and limitations.
