550-Size DC Replacement Motor for Tool Repairs

Replace a matching small DC motor in a suitable power-tool repair or motor-driven project. This listing supplies a bare 550-size motor, so the existing drive, power supply and mounting arrangement must suit it.

• ✅ Replace the motor component separately - the bare unit can be matched to an existing drive assembly.
• ✅ Plan the mechanical fit directly - the visible shaft and motor body can be compared with the original part.

Match the original motor before starting the repair

Compare the shaft, mounting points, body dimensions and electrical markings with the motor being replaced. A general 550-size description is not a promise that the unit fits every drill, screwdriver or grinder.

Use the motor only with a compatible drive and electrical system. A gearbox, controller, battery, tool housing and other assembly parts are not included, so the motor is not a complete powered tool.
