Surpass Hobby has launched a new drag racing specific sensored brushless motor, the Rocket RC 550 Drag. Designed specially for Associated DR10, Losi 22S, Traxxas Drag 1:10 linear acceleration models, key characteristics of the new motor are its light weight and small volume. Matched with the Rocket RC 220A ESC, the 6500kv brushless motor provide high torque but can also be paired with other top brands of ESC. To ensure the motor’s rotor runs smoothly at high speed it is fitted with original NMB Japanese bearings.
Rocket-RC 550 Drag Features
Output of 1200W matching with full load with large gear ratio.
The 2.0mm solder tab processing with gold-plated copper , and the frame perfectly restricts the wiring.
12 slot full slot rate winding method~internal resistance 0.0022Ω, instantaneous maximum power output.
NMB Japanese original bearing, the rotor runs smoothly at high speed.
The unique special Surpass mold stator is 0.2mm Japanese stator, and the efficiency can reach 95.2% efficiency conversion.
The rotor is wrapped with double layers of yellow imported Kavlar fiber to reduce the bursting of the rotor at high speed (without magnetic loss interference)
Strong magnetic 4pole N38AH top new magnetic material, with explosive extremely strong and temperature resistant rotor of 250°C
1EI/AIW (H) grade American MWS brand 220°C high temperature polyester wire.
German Schenck balancing machine was adjusted, and the rotor balance was accurate to within 1.6mg.
The RPM designed by finite element software can reach 75000 rpm.
