130 size brushed DC motor: Ø20.1 / 15.1 × 25.0 mm, Ø2 shaft — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/dc-motor-130-size/ (CC BY 4.0) Basis: Mabuchi FA-130RA outside size and drawing (can, flats, length, boss, shaft Ø); exposed shaft length from the Adafruit 130-size listing. Envelope only: the outside of the motor at its published sizes. The windings, magnets, brushes and bearings inside are not drawn. Catalog version: 2026-10-20 Sizes: see table below - Envelope only: the outside of the motor at its published sizes. The windings, magnets, brushes and bearings inside are not drawn. - The can is Ø20.1 round with two flats 15.1 mm apart, 25.0 mm long from the front face to the back of the end cap. - The front face has a Ø6.15 × 1.7 boss; the Ø2.0 shaft is drawn 8.0 mm beyond it (34.7 mm overall from the end cap to the shaft tip). Shaft length differs between makers and orders. - This face has no tapped mounting holes on the FA-130RA drawing; a 130 is usually held in a clip or a cradle on the flats. Some other makers' 130s add two small tapped holes: check the drawing of the motor in hand. - Terminal tabs and the rear bushing are not drawn (their sizes are not given in a form I could check). - In DIY Stirling builds, brushed DC motors of this kind are turned by the engine and used as a generator (an LED, a resistor or a meter across the leads) or as a load on the flywheel shaft. feature mm from can (round) Ø20.1 Mabuchi FA-130RA can across the flats 15.1 Mabuchi FA-130RA can length 25.0 Mabuchi FA-130RA shaft Ø2.0 Mabuchi FA-130RA front boss Ø6.15 × 1.7 Mabuchi FA-130RA drawing shaft exposed 8 (drawn from the boss) Adafruit 711, AriesRC mounting holes none on this drawing Mabuchi FA-130RA Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Mabuchi Motor: Let's Motorize: motor line-up with outside size (length × diameter) and shaft Ø for FA-130RA, RE-140RA, RE-260RA, RE-280RA, RS-380PH, RS-540SH — web — manufacturer page [verify license at link] — https://www.mabuchi-motor.co.jp/motorize/branch/motor/ - Mabuchi Motor (hosted by Pololu): FA-130RA datasheet and dimension drawing — PDF — manufacturer datasheet [verify license at link] — https://www.pololu.com/file/0J11/fa_130ra.pdf - Adafruit (product 711, as reproduced by components101): DC toy / hobby motor, 130 size: body 27.5 × 20 × 15, shaft 8 mm × Ø2 — web — listing [verify license at link] — https://components101.com/sites/default/files/component_datasheet/Toy DC motor Datasheet.pdf - AriesRC: Micro DC motors 130 / 260 / 280 / 370 / 380 / 385: listed body, shaft and hole sizes — web — listing [verify license at link] — https://www.ariesrc.gr/en/brushed-motor/21259-1pcs-micro-dc-motor-3v-6-v-12v-130-260-280-370-380-385-high-speed-carbon-brush-electric-motor.html Free files (CC BY 4.0, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/dc-motor-130-size/index.json API: https://xemstudio.com/api/geometry?object=dc-motor-130-size
