Brushless motor C17B-14

7.2 Vsmall-sizefor fans

Overview
The C17B series is a family of C.I. TAKIRON brushless motors with an outer diameter of 17.4 mm. The series includes multiple sub-models optimized for different voltages, shaft/length configurations and performance points (speed, torque, efficiency). Some sub-models (for example C17B-18) are used in compact applications such as electric fans integrated into wearable masks. The series offers multiple customizable items depending on the model (gear head, lead pin, grounding terminal, ball bearing).
