Sensored Brushless 1406-3800KV 4-Pole Motor

Drivers in all applications demand clean starts when coming off the line. Crawler fans require high-precision low speed control and torque for climbing, racers need precision and predictability, and dragsters don't have a millisecond to spare. To achieve all of these performance demands and more, we have integrated rotor position sensor technology with our improved high power and high efficiency motor design. Through the use of our sensors, the position of the rotor is always known by the ESC. This eliminates the possibility of encountering cogging or inconsistency during startup. Users will experience PRECISE throttle control and BUTTERY SMOOTH starts plus the RAW POWER and LONGER RUN TIMES that our highly efficient motors produce.

Without a robust and reliable design, efficiency will only go so far. RC enthusiasts love pushing their equipment to the edge. The Castle engineers know this and spared no expense when developing a design that could hold up to the harsh conditions that the RC community will throw at it. Oversized NMB bearings and vibration dampening system ensure the longest bearing life possible. High-strength, high-temperature grade neodymium sintered magnets combined with a high-strength Kevlar wrap ensures the integrity of the rotor is not compromised during harsh running conditions. Our proprietary winding techniques allow us to produce a stator assembly that is the lowest possible resistance, resulting in a cooler running motor. A cooler motor has a longer lifetime.

Construction of our motor required careful component selection; each verified through internal testing to ensure the highest efficiency possible. In the end, the result is a motor with unmatched quality, performance, and reliability. We wouldn't put our name on anything less.

New sensored design allows for smoother starts and better low-end throttle control while retaining the high torque and power of our previous sensorless motors.
