Engineering Overview

With coreless iron-free rotor structure and 5-segment commutator paired with precious metal brushes, FA-1213R eliminates cogging torque to realize low vibration and quiet operation. It is available with two types of reduction gearboxes (G12MF/G12XL) and optional encoders to match diverse miniature precision drive projects.
Typical Applications:
• Handheld cosmetic precision devices
• Portable small medical instruments
• Micro precision liquid pumps
• Compact laboratory testing equipment

Need custom winding or different gearbox configuration?

FA-1213R has four standard voltage versions, we can pick G12MF or G12XL reducer and match encoders according to your installation space and torque needs.
