This motor is a 15mm diameter gear reduction stepper motor with a height of 21.3mm. The output shaft can be customized with various pulley output structures such as round shaft, D shaft, screw shaft, flat shaft, etc., which can be customized according to the installation requirements of customers
The basic step angle of the motor is 18 degrees, that is, 20 steps per revolution. With the reduction effect of the gearbox, the final angle resolution of the motor can reach 0.018~0.9 degrees, which can be used in various occasions requiring precise control.
The selectable speed ratio is 1:2 1:5 1:10 1:15 1:20 1:30 1:36 1:50 1:63 1:67 1:89 1:100 1:110 1:150 1:172 1:210 1:250 1:275 1:298 1:380 1:420. Different speed ratios will produce different final torque and speed. Customers can choose according to different torque and speed requirements. Special speed ratio can be customized. If necessary, please contact us for discussion.
When selecting the motor, it is necessary to consider the speed and torque comprehensively while meeting the requirements.
This series of gear boxes adopts the most advanced processing equipment for relevant parts, with high precision, high efficiency and low noise. The plastic protective shell of the motor can protect the service life of the gear box and facilitate installation. Reasonable and reliable technology is adopted to make the product more reliable. The power input part and standard stepper motor can be in the form of probe structure, FPC, PCB cable, etc. Customizable according to customer installation requirements
