Surpass Hobby 550 Sensorless Brushless Motor for No Prep Drag Racing (6500KV)

Smooth Performance and Enhanced Control

Sensored Design: Sensors ensure smoother starts and better low-end throttle control while retaining high torque and power from our previous motors. The unique, specially designed stator, made with a 0.2mm Japanese-strength mold, achieves remarkable 95.2% efficiency conversion.

Ultimate Heat Resistance

Temperature Resistance: The rotor features double layers of imported yellow Kevlar fiber to prevent bursting at high speeds (without magnetic loss interference). Featuring an extremely strong and thermally resistant rotor with a 250°C temperature limit, and 1EI/AIW(H) grade American MWS 220 high-temperature polyester wire ensures superior performance at elevated temperatures.

Premium Components and Precision

High-Quality Material: A German Schenck balancing machine calibrates the rotor, achieving an accuracy of 1.6mg. High-strength, high-temperature neodymium sintered magnets and high-strength Kevlar wrapping ensure the rotor’s integrity under harsh conditions.

Professional and Efficient Design

Professional Winding Method: A 12-slot full-rate winding method along with an internal resistance of 0.0022 Ω allows for maximum power output with minimal stator resistance, leading to cooler operation and a longer lifespan. Quality NMB Japanese original bearings and a vibration dampening system enhance bearing longevity.

Versatile and Durable

Wide Applications: Ideal for 1:4, 1:5, 1:6, 1:8, and 1:10 scale vehicles running from 3s to 8s LiPo. Great for upgrading to a reliable, high-torque motor for 1/8th scale vehicles such as Traxxas, Arrma, Losi, Axial, Redcat, Kyosho, HPI, and Corally.
