Brushless motor C17B-20

DC12 Vsmall-size

Overview
The C17B series of brushless DC motors from C.I. TAKIRON is a family of small-diameter brushless DC motors with an outer diameter of 17.4 mm. The series includes multiple sub-models optimized for different length profiles and performance points (no-load speed/current, startup current/torque, peak efficiency and output). Certain sub-models (for example C17B-18) are used in compact applications such as electric fan-equipped masks. The series supports various customizable options depending on the model (gear head, lead pin, grounding terminal, ball bearing, lead wire, etc.).
