Posicionamiento del producto:
La barra colectora de aluminio integrada con refrigeración líquida HTD en la carcasa del motor es un componente innovador que combina soporte estructural, disipación de calor y conducción eléctrica en una única solución integrada para sistemas de accionamiento eléctrico. Al incorporar canales de refrigerante directamente en la carcasa de aleación de aluminio de alta resistencia, sirve como carcasa del motor y ruta de corriente primaria, soportando corrientes continuas de 300A–1500A. Este diseño permite el enfriamiento directo del estator, lo que reduce el aumento de temperatura del motor en más de un 15 % y aumenta la potencia máxima de salida entre un 20 y un 30 %. Con un rango de temperatura de funcionamiento de -40 °C a 150 °C y una reducción de peso del 35 % en comparación con los sistemas de barras colectoras de cobre tradicionales, es ideal para aplicaciones de alta densidad de potencia en vehículos de nueva energía y accionamientos industriales.
