DC motor A17B-08

4.5 Vcoreless

Overview
The A17B series of coreless motors (outer diameter φ17.4 mm) from C.I. TAKIRON. The series includes multiple sub-models (for example A17B-43) with variations in length, applied voltage, resistance and performance. Typical applications mentioned for A17B sub-models include small fans (eg. electric fan-equipped masks) and other compact motorized devices.
