JSUMO Symtec Q Gearmotor (12V 1450 RPM 9.28:1 44 Kgcm)

The SUMO Symtec Q Gearmotor is engineered for high-performance robotics applications where both speed and torque are critical. Designed specifically for competitive robotics such as sumo and combat robots, this motor delivers a powerful combination of 1450 RPM speed and 44 Kg·cm stall torque , making it suitable for fast acceleration and strong pushing force. The motor operates at 12V nominal voltage , with tested performance up to 24V , allowing flexible power configurations depending on project requirements. It uses a 9.28:1 hardened steel gearbox , ensuring durability and resistance against mechanical stress. A key feature is its double-bearing supported 10 mm output shaft , which significantly improves resistance to high torque loads and mechanical shocks. The gearbox housing is designed for strength and symmetry, allowing flexible mounting options in robot chassis. The motor is equipped with multiple M4 mounting holes (front, top, bottom) for secure installation. Due to its high current requirements, proper motor drivers and wiring are essential for safe operation.
