speed reducer
Gearboxes Gearheads & Speed Reducers
This motor can choose two shaft diameters 6mm and 8mm
You can choose one of the shaft diameters and the shaft type of the two will be slightly different Please pay attention to the red circle marked in the picture below.Thanks
The following is the dimension drawing of the motor with a shaft diameter of 6MM
Important reminder
Because we use different measuring tools so the measurement data of the product size will be slightly different.
If your project has high requirements for the size of the motor we recommend that you contact us before purchasing.Thank you very much!
We name the length of the gearbox L. Note that the length of the gearbox will vary with the speed of the motor. For details please refer to the L length of the corresponding parameter in the following parameter table.
The length of the gearbox is about 25.2mm to 43.6mm. The length of the gearbox is different for different speeds so please check the corresponding gearbox length in the parameter table according to the speed you choose.
The following is the dimension drawing of the motor with a shaft diameter of 8MM

The length of the gearbox is about 25.2mm to 43.6mm. The length of the gearbox is different for different speeds so please check the corresponding gearbox length in the parameter table according to the speed you choose.
The following introduces the meaning of parameter table to (B)
Reduction ratio
Input rated DC voltage
No-load speed the unit is RPM/MIN (The speed fluctuates up and down by 10%)
No-load current unit is (A)
Rated load speed the unit is RPM/MIN (The speed fluctuates up and down by 10%)
Rated load Tq unit is kgf.cm. Your project load should not exceed rated load Tq of the motor otherwise the life of the motor will be reduced or motor burned
Rated input power the unit is (W)
Maximum limit load Tq unit is kgf.cm please ignore this Tq
Maximum limit load current unit is (A) please ignore this current
Maximum limit load power the unit is (W) please ignore this power
(A) "L" Gearbox length; The length of the gearbox is abbreviated as "L" and the unit of length is mm. This refers to the length of the gearbox corresponding to the parameter you selected. As we all know the speed of the motor is different the structure of the gear inside the gear box is different so the length of the reduction box is different.
Important reminder the length of the reducer is different and the total length of the motor is also different. After you have selected the voltage and no-load speed of the motor you need to check the corresponding length of the gearbox and then you can refer to the size diagram below to get the motor total length.
(B) Approximate net weight of the motor the unit is (g)
Refer to the following diagram to simply calculate the Tq required for your project that is the Tq of the motor you should choose.
The following are Figures A and B respectively
The radius of Figure A is 1CM which means that the radius of the object driven by the motor is 1CM and the weight of the object is 10KG then the motor Tq you need to choose is 10KG.CM;
The radius of Figure B is 10CM which means that the radius of the object driven by the motor is 10CM and the weight of the object is 10KG then the motor Tq you need to choose is 100KG.CM;
Simply put the load of your project needs to be inferred from the radius of the object not just the weight of the object.
It is calculated as follows
Calculate the required Tq = the radius of the driven object CM* times the weight of the object
