Castle 1406 Sensored Motor - 1900Kv
Product #: 060-0068-00
For more than a decade Castle has been providing award winningbrushless sensorless motors to R/C enthusiasts worldwide. In responseto overwhelming requests by our customers, we have brought technologicaladvancements together that will deliver unprecedented performance inour new SENSORED motor Line. Our latest additions are the 1406 series in a "SLATE" color, in 1900KV, 2280KV, 2850KV and 3800KV. These motors are ROCK READY and we have the startup on low RPMs under control. Castle now has you covered if you are looking for ultimate control out on the trails or on your Ultra 4 track days.
WHY SENSORED?
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.
WHAT MAKES AN EXCEPTIONAL MOTOR?
When tasked with designing a sensored motor our engineers started with the question,
“What makes a motor great?”
- Efficiency
- You can push it harder (gear it up)
- You can run it longer (with the same battery)
- It stays cool under extreme loads
- Reliability
- Ability to withstand the harsh demands of any RC application
- Long-life, high-quality components
- Proven manufacturing techniques
EFFICIENCY IS KEY
The higher the efficiency of a motor the more power it can produce without overheating, which allows you to safely run higher gear ratios. The higher the efficiency of a motor, the less power it takes to produce the same output power, which allows you to run longer on a single charge. The higher the efficiency of the motor, the less energy it turns into heat; keeping it cool under extreme loads. Efficiency equals performance.
RELIABILITY CAN’T BE IGNORED
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.

THE DESIGN: KEEPING IT COOL
- Our IMPROVED 4-POLE 12-SLOT design boasts exceptional EFFICIENCY and produces LESS HEAT.
- QUIETSENSE™ technology shields the sensors from magnetic field noise generated from the motor coils and keeps your motor and ESC in sync at all times. Use of a Flux Shield™ in conjunction with secondary Sense Magnets delivers even HIGHER PRECISION and MORE EFFICIENT startups.
- Our OPTIMIZED design eliminates the need for mechanical timing adjustments. Our sensor alignment method delivers uniform timing and torque in both directions, automatically.
- REBUILDABLE design allows users to replace front end bell/bearing assembly or rotor/shaft assembly.
- ROAR standard sensor port and labeled connections.
- Updated modern and sleek design; looks as cool as it performs.

Immense care is taken by our US design team during every step of thedevelopment process. While using the highest quality components isimportant, design is equally important. Our experienced, in-houseengineering team, located in Olathe, Kansas, has spent countless hourssimulating and developing the most efficient design. Developmentincludes magnetic simulations, custom winding techniques, and rigorous,real-world testing of the final product.
During a 5-minute constant power dyno test the results were clear.When producing 200W of power, our competitors’ motors increased intemperature over 20% more than the Castle 1406 Sensored motor. Whenproducing 300W of power, it wasn’t even close, their temperature climbedat over twice the rate of the Castle motor and then overheated inaround two minutes while the Castle motor powered through and completedthe test. _Click here for graph_
* Competitors’ motors is average of several 7.5T 2-pole motors typically used in mod-style racing.
You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder.
We take OVERPOWERING seriously.
INTEGRATED SOPHISTICATION
Castle engineers always add a little something extra in their designsthat takes your performance to the next level. We have not skimpedhere. Many customers have utilized our industry leading softwarefunctionality that Castle Link* offers. When paired with a Castle Creations sensor supported ESC, like the MAMBA MICRO X, MAMBA MAX PRO, MAMBA X or MAMBA MONSTER X, you can unlock advanced tuning capabilities that Castle Link provides specifically for sensored motors.
SMARTSENSE™ uses the motors sensors to start the motor toprovide smooth starts, excellent torque, and low-speed drivability.Once the motor is turning, it seamlessly transitions to Castle’s ULTRA- EFFICIENTsensorless mode. When running, a motor must transition betweendifferent load points and a different timing advance is required foroptimal efficiency at all load points. Using mechanical timingadjustments alone, you can only target one driving condition, such ashigher start power or higher top end speed. This sacrifices performanceand efficiency during the other driving phases. Electronic timing in SMARTSENSE™will advance timing automatically for peak performance during alldriving conditions. This allows users to combine the best of both worldsin an unrivaled HYBRID between smooth sensored startups and high-efficiency sensorless drive.
With a Castle sensored ESC and sensored motor you will have the ULTIMATE POWER PLANT for your vehicle. Users will experience PRECISE throttle control, BUTTERY SMOOTH starts, PEAK PERFORMANCE and EFFICIENCY throughout the full throttle range. You will feel the POWER and LONGER RUN TIMES that a WORLD-CLASS motor produces.
It’s not magic… it’s SMARTSENSE™.
