Product Detail

Product Tags


This 8mm diameter miniature stepping motor is combined with 8mm*10mm precision metal gearbox.
The basic stepping angle of the motor is 18 degrees, i.e. 20 steps per revolution. With the deceleration effect of the gearbox, the final rotation angle resolution of the motor can reach 1.8~0.072 degrees, which can be used in many fields requiring precise control of the rotation position.
We have 1:10 1:100 1:200 1:250 gear ratios for you to choose from, in addition to customizing the reduction ratio for special requirements. The larger the reduction ratio, the higher the motor torque and the slower the motor speed. Customers can match the speed ratio according to the different requirements of the use of torque speed, and at the same time, given the appropriate stepper motor drive frequency to achieve speed and torque determination. Please confirm the gear ratio before ordering.
Customers can match the gear speed ratio according to different requirements of using torque speed, and the gearbox has 1:2 - 1:1000 gear ratio for customers to choose.

About geared stepper motors

1.The power input part of the standard stepper motor is available in the form of FPC, FFC, PCB cable, etc.

2.For output shaft, we have two different types of standard shafts:D shaft and screw shaft. If a special axis type is required, we can also customize it, but there is an additional customization cost.

3.8 mm diameter permanent magnet stepper motor with 10*8 mm gear box. The gear box has high precision, high efficiency and low noise, which makes the product have good reliability.

About GB10 gearbox

1. The efficiency of worm gearbox is 58%~71%.
2. The gearbox uses the most advanced equipment in the world to process the relevant parts, so the high precision, high efficiency, low noise, and reasonable and reliable technology make the product have good reliability.
 3. The output shaft of GB10 gear box has D shaft and screw shaft for customers to choose. As the following picture:



Geared stepper motors, widely used in Smart home, personal care, home appliance equipment, smart medical equipment, smart robot, smart logistics, smart cars, communication equipment, smart wearable devices, consumer electronics, camera equipment, and other industries.


Customization Service

1. Coil resistance/rated voltage: The coil resistance is adjustable, the higher the resistance, the higher the rated voltage of the motor.
2. Bracket design/slider length: If customers want longer or shorter bracket, there are special design, such as mounting holes, it is adjustable.
3. Slider design: the current slider is brass, it can be replaced with plastic to save cost
4. PCB+cable+connector: PCB design, cable length, connector pitch are adjustable, can be replaced with FPC according to customer's need.
