Brushless motor C17B-28

BLDC12 Vsmall-size

Overview
The C17B series of brushless motors by C.I. TAKIRON. Outer diameter for the series: 17.4 mm. Typical applications: small fans, micro blowers and other compact motor-driven devices. Multiple sub-models are available with different lengths, applied voltages, terminal resistances, no-load speeds/currents, startup currents/torques and maximum efficiency/output characteristics.
