Brushless motor C17B-19

24 Vsmall-sizefor fans

Overview
The C17B series of brushless motors by C.I. TAKIRON is a family of φ17.4 mm outer-diameter micro brushless motors offered in a variety of lengths, voltages and performance points. Typical applications include compact fans and small motorized devices (examples: electric-fan-equipped masks). The series includes multiple sub-models optimized for different voltages, speeds, torques and efficiencies.
