9 V motor A17B-34

corelesssmall-sizelightweight

Overview
The A17B series of coreless motors from C.I. TAKIRON (outer diameter φ17.4 mm) comprises multiple submodels covering different lengths, applied voltages and terminal resistances. Typical applications include compact fans (for example mask fans) and other micromotor systems that require high power density in a small diameter form factor.
