AE4812
2.9 W, 15 V Ø48 mm BLDC motor from Topband Motor: 0.04 N·m rated at 695 rpm.
Figures are copied from the maker’s published datasheet; curves are calculated from them. Confirm with the manufacturer before ordering. Not stated on the datasheet, estimated from it: torque constant (fitted to the rated point), resistance (fitted to the rated point), inductance, rotor inertia, insulation class, IP rating.
