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: output-shaft model constants (fitted to the datasheet's no-load and rated points), no-load current, inductance, rotor inertia, weight, shaft diameter, insulation class, IP rating.

+ Add to compare

Same 555 motor with a right-angle worm gearbox (self-locking) instead of a spur gear train.
