DC motor A17B-41

18 Vcorelessfor medical applications

Overview
The A17B series of coreless motors (outer diameter φ17.4 mm) from C.I. TAKIRON. The series includes multiple sub-models (example: A17B-43) used in small electric devices such as fans for powered masks. Individual model specifications (rotation speed, torque, current, voltage, terminal resistance, efficiency, output) are provided per model. Product pages include gallery images and a product video for representative models.
