DC Micro Motor — RF-300CA-14270 (0.5–4.0 V)

A low-current, 24 mm micro DC motor suited to solar demos, battery-powered builds, and small device repairs. This RF-300CA-14270 variant uses precious-metal brushes with oil-impregnated bearings for smooth, efficient operation at very low voltages (down to 0.5 V). It can run from one or two AA cells, small solar panels, or regulated bench supplies. Core specs and construction details are confirmed from the manufacturer datasheet and your product page.
