Product SeriesCoreless motors A12B series (outer diameter φ12 mm). This series includes multiple sub-models (A12B-24, -37, -36, -35, -33, -32, -27, etc.) with differing shaft lengths, applied voltages and electrical/mechanical performance. Specification tables for each sub-model list rotation speed, currents (no-load/startup), torque, efficiency and output. Outline drawings and CAD data are available for download, and sample/customization support is provided for the series.
