Brushless motor RB-8530-C8 series

BLDC6 V12 V

Product Overview
RB-8530-C8 is a Brushless DC Motor (BLDC) from KWC Motor in the 85 mm class with an external-rotor option. It delivers high continuous torque (rated up to 1.02 N·m / 10,200 g·cm) and peak power in the 200–210 W range. Voltage and performance can be customized across approximately 6 V–40 V. The motor is designed for low-speed, high-torque applications requiring quiet, stable operation and industrial-grade durability.

Key Facts for Engineering Buyers

• Product category: Brushless DC Motors (BLDC)
• Motor family: External-rotor BLDC, 85 mm class
• Brand / manufacturer: KWC Motor
• Typical applications: high-flow oxygen concentrators, medical equipment, service robots, pumps and automation drives

Specification Signals

• Diameter: 85 mm (external rotor dimension also referenced as 92.5 mm)
• Body length: ~75 mm
• Rated torque: up to 1.02 N·m (10,200 g·cm)
• Stall torque: up to ~11 N·m (application-dependent)
• Output power: ~200 W class (model variants list 205–210 W)
