Coreless motor A12C-38

for medical applicationsprecision

Overview
Coreless A12C series motors with an outer diameter of φ12.4 mm. The series includes multiple sub-models tailored for different industrial and precision applications (examples: A12C-30 for dental devices, A12C-31 for SLR, A12C-20 for surveillance cameras). Sub-models vary by length, applied voltage, terminal resistance and performance to match speed, torque or low-current requirements.
