This is a 15 mm stepper motor with a worm gearbox. There are 1 and 2 heads of worm gear, which can be understood as 1 and 2 teeth. The number of heads is selected according to the gear ratio, and the efficiency of worm gear is relatively low at 22%-27%.
Customers can choose according to their choice of gearbox gear ratio.
21:1,42:1,118:1,236:1,302:1,399:1,515:1,603:1,798:1,1030:1.
In addition to these gear ratios, customers can also customize the speed ratio as needed, which is generally possible.
The larger the transmission ratio, the slower the output shaft rotation and the higher the torque.
Output shaft torque=motor torque*reduction ratio*gearbox efficiency
15mm motor torque is usually at 15g.cm
With a gearbox with 118:1 gear ratio
Gearbox efficiency is about 24%
The output torque is approx:15g*cm * 118 * 0.24 = 424 g*cm
| Model No. | SM15-818G |
| Motor diameter | 15mm |
| Motor type | Permanent magnet motor |
| Drive voltage | 5V DC |
| Coil resistance | 31Ω±10%/phase |
| Number of phase | 2 phases |
| Step angle | 18° |
| Gear ratio | 21:1~1030:1 |

| EFFICIENCY | 22%-27% |
The gear box has high precision, high efficiency and low noise, which makes the product have good reliability.
The power input position of the stepper motor can be in the form of FPC, FFC, PCB cable, etc.
The output shaft of the motor can adopt various output structures, such as circular shaft, D-shaft and wire bar.
N20 DC motor + worm gear box
1. worm gearboxes are inefficient (less than 30%) and will have lower output torque than other types of gearboxes.
2. Worm gearboxes have a self-locking function, which will automatically lock when the motor is powered off.
3. It can also be used with 15mm dual stepper motors, N20 motors, 10mm stepper motors and 20mm stepper motors, which customers can choose according to their needs.
As shown in the figure below:
