NovaStar 9V 2000 RPM Coreless (Ironless) DC Motor with Planetary Gearbox
The NovaStar 9V 2000 RPM Coreless DC Motor with Planetary Gearbox is a high-end robotic motor developed for line follower robots and high-speed mini sumo robots. It provides a permanent solution to common issues found in standard DC motors, such as low build quality, inefficient power transmission, and gear breakage.
Designed for competition and performance-oriented robotic projects, this motor combines **custom-wound coreless motor technology** with a **fully metal planetary gearbox**, delivering high speed, strong torque, and long service life.
Premium Design and Manufacturing Approach
The motor and gear system of the NovaStar Coreless Planetary Motor are designed based on high-end industrial motor manufacturing principles. The internal motor structure and planetary gearbox geometry have been optimized with reference to engineering approaches used in Maxon motor design philosophy.
The coreless winding structure is developed for rapid acceleration and high efficiency, while the planetary gear system is manufactured entirely from metal to ensure stable and long-lasting operation under high torque. As a result, this motor offers quieter, smoother, and more stable performance compared to standard DC motors.
