A high torque brushless DC motor stator is the stationary laminated core designed to maximize torque output while maintaining compact form factors. High torque density is achieved through optimized slot geometries, advanced lamination materials, and precise winding patterns. Modern high torque BLDC motors utilize 4-pole rotor designs to increase torque density compared to 2-pole alternatives, enabling rigid speed-torque characteristics and stable performance under varying loads .

Reenives manufactures high-quality high torque BLDC stator cores using non-grain oriented silicon steel (0.20-0.35mm) with advanced C5/C6 epoxy coating — reducing eddy current losses by up to 38% and enabling high torque density for demanding propulsion applications .

Reenives offers high torque BLDC stator cores in multiple configurations to meet diverse high-torque application requirements :

• By Slot/Pole Config: 12N14P (balanced torque/speed), 18N20P (high torque density), 24N28P (maximum torque for heavy-lift), 30+ slot configurations for aviation-grade smoothness .
• By Material Thickness: 0.20mm (standard high-performance), 0.15mm (ultra-high performance, minimum eddy loss), 0.27mm, and 0.35mm (heavy-duty) .
• By Insulation Coating: C5 epoxy powder coating (Class H, 180°C) with >2000V dielectric strength; C6 grade for superior thermal conductivity in high-power density applications .
• By Core Architecture: Segmented stator cores (modular for fault-tolerant winding) and integrated circular laminated stacks (one-piece for maximum structural integrity) .
