Specifications Specifications: Values: KV: 2300rpm/V Input Voltage: 7.4V-11.1V (2S-3S) Max Watts: 63.0W Suggested ESC: 7A-12A Weight: 12g (0.42oz) Motor Diameter: 18mm (0.70in) Motor Length: 15.1mm, motor only Wire Length: 105mm (4.13in) Wire connection: Stranded wire only, no connectors for a soldered connection. Shaft Diameter: Shaft Length: 14mm (0.55in) BX 1306 Mounting Holes: Four M2 spaced 9mm (0.35in) 90degrees offset. BX 1306 Wiring: Connect the three ESC wires any way you like. If the motor is spinning backward, you can reverse the direction of any brushless motor by swapping any two wires. Brushed vs Brushless In case you’re wondering why brushed vs brushless, here’s a great article that explains the difference and when to use each: https://www.arrow.com/en/research-and-events/articles/powering-a-battlebot Here’s another: https://battlebots.fandom.com/wiki/Brushless_vs._Brushed_Motors Brushless motors are almost universally used for weapons motors, for the reasons listed in the article. Brushless motors are now becoming more popular as drive motors for combat bots as well, with brushless varieties for antweight and beetleweight bots now available. Brushless Motor Confusion But wait! These articles talk about how brushless motors are more efficient than brushed motors! Why do brushed motors dominate smaller bot classes as drive motors? Some simple reasons: Brushed motors are generally much cheaper. They have more power and torque at low speeds. Controllers only require two wire connections: simpler, less expensive controllers. All of the above means a lower cost and weight penalty. Most importantly, adequate drives with the right gearing and price point are generally much less available in form factors suitable for drive motors in smaller bots. But this is changing. Fingertech and Repeat Robotics have now come out with brushless drive motors for beetleweights, and Repeat now has a model for antweights.
