280 DC Motor, DC can motor

A 2 mm shaft, 12.2 mm long, comes out of the 24.2 mm can of the 280 DC motor (DC can motor), which is 30.5 mm long. It mounts by two 2.3 mm holes 14 mm apart. Here as simplified STEP files. Modeled from Mabuchi's RC-280RA and Johnson Electric's NF213G drawings. Johnson Electric's NF213G is flat-sided (#1369 item 1); its face and shaft back this round can.

What each maker states

• Where the makers' drawings differ, the model takes the largest stated, so a mount made to it clears every maker's motor (ADR 0134 row 4): shaft length E 12.2 mm (Johnson Electric 10.5, Mabuchi 12.2); front boss B 6.35 mm (Johnson Electric 6.15, Mabuchi 6.35); rear boss Br 8.5 mm (Johnson Electric 6.25, Mabuchi 8.5); rear boss height hr 2.8 mm (Johnson Electric 2.8, Mabuchi 2). Check your own motor's drawing where it matters.
