DC motor A22C-12

brushed6 Vcoreless

Overview
The A22C series coreless motors have an outer diameter of φ22 mm and comprise multiple sub-models with differing lengths, applied voltages and performance points. Length variations (25.3 mm and 30.3 mm), applied voltage range (3.0–24.0 V) and distinct electrical/mechanical characteristics allow selection for precision instruments and compact actuators. CAD outlines and catalog material are available from the manufacturer for selected models.
