20mm Diameter Stepper Motor With Gearbox 20BY45-20GB Multiple Gear Ratio Optional
20BY45-20GB is a 20BY45 permanent magnet stepper motor attached
with a GB20 20mm diameter gearbox.
The step angle of the single motor is 18°/step.
With different gear ratio, it would have different output speed and
torque performance.
If customers want more torque, we suggest to user higher gear
ratio.
If customers want higher output speed, we suggest to keep gear
ratio down.
The length of gearbox is related to gear levels, with more levels,
there are more gears, and it makes the gearbox longer:
Gear levels: 3/4 levels, gearbox length 16mm, gear ratio:
10:1~31.25:1
Gear levels: 5 levels, gearbox length 17.5mm, gear ratio:
50:1~78.1:1
Gear levels: 6 levels, gearbox length 19mm, gear ratio:
100:1~195.3:1
Gear levels: 7 levels, gearbox length 20.5mm, gear ratio:
250:1~488.3:1
