DC motor A12B-35

3 Vcoreless

Overview
The A12B series of coreless motors (outer diameter φ12 mm) provides multiple sub-models with different lengths, rated / applied voltages, terminal resistances and performance characteristics. The series specification tables list, per sub-model: rotation speed (no-load), currents (no-load and startup), startup torque, efficiency and output. The page includes product detail sections (product images, gallery and video thumbnails) and per-model technical tables.
