Castle 1406 Sensored Motor - 7700kv

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 dont have a millisecond to spare. To achieve all of these performance demands and more, Castle has integrated rotor position sensor technology with Castles improved high power and high efficiency motor design. Through the use of Castles 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 Castles highly efficient motors produce.

WHAT MAKES AN EXCEPTIONAL MOTOR?

When tasked with designing a sensored motor Castles 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

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. Castles 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 Castles 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. Castle wouldnt put their name on anything less.

Castles IMPROVED 4-POLE 12-SLOT design boasts exceptional EFFICIENCY and produces LESS HEAT.

Castles OPTIMIZED design eliminates the need for mechanical timing adjustments. Castles 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.

You will reap the benefits of longer run times on one battery and a cooler running motor that can be pushed harder.

SMARTSENSE uses the motors sensors to start the motor to provide smooth starts, excellent torque, and low-speed drivability. Once the motor is turning, it seamlessly transitions to Castles ULTRA- EFFICIENT sensorless mode. When running, a motor must transition between different load points and a different timing advance is required for optimal efficiency at all load points. Using mechanical timing adjustments alone, you can only target one driving condition, such as higher start power or higher top end speed. This sacrifices performance and efficiency during the other driving phases. Electronic timing in SMARTSENSE will advance timing automatically for peak performance during all driving conditions. This allows users to combine the best of both worlds in 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. Its not magic its SMARTSENSE.

Castle recommended applying dielectric grease to the outside of the sensor wire connections after installation of the wire. Routine maintenance is recommended after running in wet conditions. Please refer to this document for running and maintaining motors in wet environments.
