Brushless motor C17B-26

7.4 Vsmall-sizelow-voltage

Overview
The C17B series of brushless motors by C.I. TAKIRON features an outer diameter of 17.4 mm. The series includes multiple sub-models (examples: C17B-23, C17B-22, C17B-07, C17B-25, C17B-24, C17B-16, C17B-13, C17B-18, etc.). Typical application examples include small electric fans (e.g., for mask fans) and other compact electric appliances. The site lists per-model electrical and mechanical specifications (rotation speed, currents, torque, efficiency, output), dimensional data and downloadable CAD/external drawings and catalog materials (catalog pages, product pages and gallery images available).
