DC motor A12C-29

12 Vcorelessfor the mining industry

Overview
The A12C series coreless motors from C.I. TAKIRON have an outer diameter of φ12.4 mm and are available in multiple lengths (examples: 21.5 mm, 24.8 mm, 30.8 mm). Models are configured for different applications such as dental treatment equipment, single‑lens reflex cameras and surveillance cameras. The series covers a range of applied voltages, terminal resistances, no‑load speeds and torques to meet varied application requirements.
