Performance by Voltage and Motor Type
The type identifiers 11,13,16 and 34 correspond to different motor references. Use the table matching both voltage and type. Bare-motor speed is a separate reference from geared output speed. Rated torque is shown in the unit stated for each table;gf·cm and kgf·cm are different scales.
A dash means no reliable individual figure is specified. Maximum 3 entries mean a 3.0 kgf·cm gearbox ceiling in the indicated condition,not a guaranteed stall or continuous output rating. Do not operate stalled or overloaded.

Shaft Fit,Mounting and Wiring
The complete shared drawing shows a 10 mm shaft projection. Select the 4.4 mm option for the shorter projection and do not infer that all10 mm drawing dimensions describe it. Confirm the 3 mm shaft,2.5 mm flat,M2×0.4 front holes,shaft register and mechanism clearance before installation.
The bracket illustration is a GM13/GM16 family fit reference and includes a motor pictured for installation context. It does not define every selected motor's body dimensions. Check the 25 mm bracket width,19 mm upright,1.2 mm thickness and mounting slots against the actual motor and mechanism.
Use DC voltage matching the selected winding. Reverse the bare motor-terminal polarity with suitable switching to change direction. A controller's own supply-input polarity must follow its actual markings. For the controller package,confirm actual supply and current ratings before connection;the package name does not establish a universal3–24V controller rating. Do not connect the motor or controller board directly to household AC.
Applications
Compatible small self-balancing vehicles,line-following robots,appliance mechanisms,pan-tilt drives and motorized tape-cutting mechanisms where the selected speed,load,voltage and mounting fit. Select by rated running performance and avoid stalled or overloaded operation.
What's Included
| Selected package | Contents |
|---|---|
| Motor Only | 1 gearmotor at the selected ratio,motor type and shaft projection |
| Motor + Mounting Bracket | 1 selected gearmotor and 1 mounting-bracket assembly |
| Motor + Bracket + Speed Controller + S Lead Pair | 1 selected gearmotor,1 mounting-bracket assembly,1 speed-controller assembly and 1 S lead-pair assembly |
A power supply,host controller and application equipment are not included. Controller and lead connector specifications are not established by the shared motor/bracket photos. Motor-only selections do not include the bracket,controller or lead pair.
FAQ
Does Type 11 mean an 11 mm motor frame?
No. It is a motor-type identifier used with the voltage/winding references. Use the mechanical drawing for dimensions.
Can any version operate across3–24V?
No. Match the selected voltage and motor type. A family voltage range does not replace the selected winding's rating.
Do the photos show the 4.4 mm shaft?
The shared mechanical reference shows10 mm. Select the required projection and check its fit before installation.
Is3.0 kgf·cm a guaranteed stall torque?
No. The marked values are maximum permissible gearbox limits. Avoid stalling and overload.
Does the motor-only selection include the controller or bracket?
No. These are included only in the corresponding named package.
