15mm Worm Gear Stepper Motor with Worm Gearbox Gear Ratio Selectable

15mm Worm Gear Stepper Motor Description:

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
