Brushless motor C17B-27

7.4 Vfor micro motor

Overview
The C17B series of brushless micro motors by C.I. TAKIRON Corporation features a common outer diameter of φ17.4 mm and a wide range of sub-models with variations in length, rated voltage, terminal resistance, no-load speed/current, startup current/torque and maximum output. Selected sub-models (for example C17B-18) are used in compact electric fans integrated in wearable products and other small ventilation applications. Mechanical drawings and CAD data are available for download from the manufacturer's product resources.
