Brushless motor RB-2430-9C series

BLDC6 V12 V

Product Overview
RB-2430-9C is a 24 mm-class Brushless DC Motor (BLDC) with an extended 30.8 mm body and external-rotor construction. The longer magnetic circuit and increased winding space provide higher torque density (series max up to 76 g·cm) while maintaining a compact footprint. Suitable for precision, high-load small drives in medical and industrial equipment.
