DC motor A12C-34

5 Vcorelessmicro

Overview
Coreless motor series A12C (outer diameter φ12.4 mm). Models differ by length and electrical characteristics to suit precision applications such as dental/medical handpieces, SLR and surveillance camera actuators, and other compact drives. Standard lengths include 21.5 mm, 24.8 mm and 30.8 mm depending on the model.

Key specifications

• Outer diameter: 12.4 mm (φ12.4).
• Lengths: 21.5 mm, 24.8 mm, 30.8 mm (model-dependent).
• Applied voltage: typical models from ~3.0 V to 12.0 V.
• No-load speed: up to about 24,800 r/min depending on model.
• Terminal resistance, no-load/startup currents, startup torque, max efficiency and output power are model-specific — consult the model table for exact values.
• Peak example output: up to 12.6 W (A12C-31).
• Maximum observed efficiency: up to ~84.6% (A12C-38).
