| Max Recommended Vehicle Weight: | 8lbs when used for low speed/moderate driving style like rock crawling and trail running; 5lbs for more racing and aggressive driving styles. |
| Product Use Statements: | Monitor motor temperatures closely; overheating a motor will cause permanent damage to the magnets. Never exceed 180° F on the the motor or ESC. |
| Running Modes: | SmartSense™ (with Castle Sensor capable ESC), Sensored and an ultra-efficient Sensorless mode. |
| Tech Tips: | Water Resistant Design: The sensor board is coated with silicone conformal coating to protect the sensors from moisture. The sensor connections are not water resistant; water can cause signal loss which could result in loss of sensored capabilities. Castle recommends 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. |
The Design: Keeping It Cool
Immense care is taken by our US design team during every step of the development process. While using the highest quality components is important, design is equally important. Our experienced, in-house engineering team, located in Olathe, Kansas, has spent countless hours simulating and developing the most efficient design. Development includes 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 in temperature over 20% more than the Castle 1406 Sensored motor. When producing 300W of power, it wasn’t even close, their temperature climbed at over twice the rate of the Castle motor and then overheated in around two minutes while the Castle motor powered through and completed the test.
*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.
