755 DC Motor – 12V/24V High-Speed Threaded Shaft Motor

755 DC Motor – 12V/24V High-Speed Threaded Shaft Motor for Grass Cutters

The 755 DC Motor is a high-speed, high-torque brushed motor built for battery-powered garden tools — most commonly used to build or repair DIY grass cutters, cordless trimmers, and lithium-powered lawn mowers. It runs on both 12V and 24V lithium battery systems, giving you flexibility depending on the power source and cutting performance you need, with speed and torque scaling up as voltage increases.

The motor comes with a threaded output shaft (5mm diameter) designed to bolt a cutting blade or trimmer head directly on, along with M4 mounting holes for securing it to a mower or trimmer housing. Inside, it uses a forged metal case with a pure copper coil and a built-in cooling fan to manage heat during extended high-RPM operation, so it holds up under continuous outdoor use. It’s a popular choice among makers building a grass cutter from scratch, since the threaded shaft and mounting pattern are ready to accept a blade with no extra machining.
