DC motor A16B-33

12 Vcorelesscompact

Overview
The A16B series of coreless DC motors (outer diameter φ16 mm) from C.I. TAKIRON is a family of small-diameter coreless motors offered in multiple sub-models (examples: A16B-33, A16B-31, A16B-29, A16B-27, A16B-25, A16B-22, A16B-10, A16B-09, A16B-07, A16B-04, A16B-03). Typical applications include electronic locks (security doors) and other compact electromechanical devices. Outline drawings and CAD data are provided by the manufacturer for download. The series supports customization such as gear heads, lead pins, lead wires and grounding terminals.

Notes
Values above come from manufacturer datasheet tables per model within the A16B series (columns: model, outer diameter, length, applied voltage, terminal resistance, no-load speed & current, startup current & torque, maximum efficiency, maximum output). Specific sub-model selection is required to match exact terminal, voltage and performance requirements.
