Why a Planetary Gearmotor? In combat robotics, drive motors are exposed to repeated shock loads, sudden reversals, and side impacts that quickly reveal the limits of traditional spur gearboxes. Planetary gearboxes distribute load across multiple gears and through a rigid carrier and ring, significantly improving impact resistance while increasing torque capacity within the same diameter envelope. The Turnabot N10 Planetary Gearmotors are built around a true 12mm all-metal planetary gearbox, offering a substantial durability upgrade over spur gear motors of similar size. This design helps resist shaft bending, gear tooth shear, and retention failures that commonly end matches early in small weight classes. Compact, Durable, and Weight-Efficient Designed specifically for very small combat robots and tightly packaged mechanisms, the N10 planetary format delivers impressive torque while keeping overall mass to a minimum. Weights start at just 13.8g, allowing builders to allocate more weight to armor, weapons, or additional drive motors without sacrificing drivetrain reliability. Compared to larger 16mm planetary gearmotors, the N10 format provides meaningful weight savings while remaining compact enough for narrow chassis layouts, articulated mechanisms, and space-constrained drivetrains common in the smallest competitive robots. Output Shaft and Wheel Retention Each N10 planetary gearmotor features a robust output shaft with a machined retention notch and ships with a circlip for secure wheel retention. This system dramatically improves resistance to wheel loss under weapon hits and wall impacts, a frequent failure mode for small spur gearmotors and smooth-shaft designs. Speed, Torque, and Electrical Considerations The Turnabot N10 Planetary Gearmotors are available in multiple speed options to suit different drive styles and applications. Published RPM values should be considered typical measured performance under standard conditions; engraved motor markings may not reflect final output speed once installed in a planetary gearbox or operated at different voltages. Manufacturer testing and recommendations frequently reference Malenki Standard and Malenki HV brushed ESCs, which are known to work well with these motors. Other brushed ESCs may also be used, provided their current capability and voltage ratings are appropriate for the selected motor variant and battery configuration. Always verify ESC and battery specifications when designing your drivetrain.
