Fine workmanship and a userfriendly design make installation and use straightforward. Key features Model: Electronic Starter 25GA 370 Shaft diameter: approx. 4 mm for compatibility with common couplings, gears, and pulleys Voltage options: DC 6 V, DC 12 V, DC 24 V Speed options: 12 RPM, 16 RPM, 26 RPM, 35 RPM, 60 RPM, 130 RPM, 170 RPM, 280 RPM, 620 RPM, 1360 RPM Build quality: fine workmanship for smooth rotation and reliable fit Installation: compact size and standard shaft make mounting and wiring quick and easy Why choose this motor Flexible power and speed choices let you select the exact combination needed for your application without extra modifications. Standard 4 mm shaft simplifies mechanical coupling to gears, pulleys, and encoders, reducing setup time. Multiple voltage options ensure compatibility with common DC power supplies and control systems. Clean construction and precise machining reduce wobble and simplify alignment during installation. How it solves common problems Eliminates the need to rework shaft fittings by using a common 4 mm diameter that pairs with widely available couplings and gears. Provides a range of preconfigured speeds so you can match performance requirements without extensive motor tuning. Simplifies integration into prototypes and small machines thanks to a compact form factor and straightforward electrical requirements. Typical applications Hobby robotics and small automated mechanisms: use lower RPMs for precision actuation or higher RPMs for driving wheels and propellers. Educational and prototype electronics: quick integration into breadboarded motor controllers, driver boards, and hobby kits. Small automation and display systems: drive turntables, conveyor segments, or rotating signage where compact size and selectable speed are important. Technical notes Ensure the chosen voltage matches your power supply and motor controller specifications. The approx. 4 mm shaft is suitable for most small couplings and gears; confirm coupling bore size before final assembly. Select the RPM option that fits the torque and speed requirements of your application. This Electronic Starter 25GA 370 delivers a compact, easytoinstall solution with multiple voltage and speed options, making it a practical choice for hobbyists, educators, and smallscale automation projects.
