The main focus in the development process was the highest possible efficiency and power output and so the Pure 2 features a higher power rating at improved temperature characteristics and super low friction. The dual axis balanced 12.5mm sintered worksteam rotor guarantees precise running and significantly improved efficiency. Nosram’s preciSensor system and the extra large ball bearings further boost the motors performance. Finally the ultra lightweight, precision machined 7075-T6 aluminium housing features optimized cooling cut-outs for lowest running temperatures at full power output. The full lineup includes 10.5, 9.5, 8.5, 7.5, 6.5, 5.5, 5.0, 4.5 & 4.0 turns.
