Product Description

12vDC Geared Stepper Motor PM25 Micro Gearbox Motor 25mm Permanent Magnet Geared Stepper Motor 


This motor is a 25 mm diameter motor with a height of 25 mm. The basic step angle of the motor is 7.5 degrees. After the reducer decelerates, the step angle resolution can reach 0.075~0.75 degrees, which can achieve accurate position control and other functions.
Product standard gear reduction ratio: 1:10 1:15 1:20 1:30 1:30 1:60 1:75 1:100
On the basis of matching reducer with stepping motor, the stepping motor adopts an external reducer with built-in structure and metal gears, which are easy to transmit greater torque
This product is mainly used for toilet valve, camera, PTZ and other occasions.
