High precision 20mm pm stepper motor with circular gearbox
This is a circular gearbox with a 20mm PM stepper motor.
The resistance of the motor is selectable from 10Ω, 20Ω, and 31Ω.
The gear ratios of the circular gearbox, the gear ratios are 10:1,16:1,20:1,30:1,35:1,39:1,50:1,66:1,87:1,102:1,153:1,169:1,210:1,243:1,297:1,350:1,
The efficiency of circular gearbox is 58%-80%.
The larger its ratio, the slower the output shaft rotation speed and the higher the torque.
The customer evaluates the gear ratio according to the torque required.
If you are interested in purchasing some samples for testing, please feel free to contact us.

Round Gear Box Gear Ratio Specifications
About circular gear type
1. The gear box has high precision and high efficiency.
2. Round gear box output shaft is generally φ3mmD2.5mm shaft, and the length of output shaft can be customized.
3.The output speed and torque are different for different gear ratios Customers evaluate the gear ratio according to the required torque.
4. The round gear box can also be paired with 15mm stepper motor.
The following chart shows a 15mm stepper motor with a circular gearbox：
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.
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.
