High speed 2:1 to 1000:1 gear ratio N20 DC brushed motor with GB12 gear ratio
Description:
This is a N20 DC motor with gearbox.
N20 is typical brushed DC motor, and for a single motor, unloaded speed is about 15000RPM.
When the motor is attached with a gearbox, it’s speed with be much lower, and its torque will be much bigger.
The gear ratio is 2:1 to 1000:1
For gear ratio below 420:1 (including 420:1), gearbox length is 9mm.
For gear ratio over 420:1, gearbox length is 12mm

Gearbox increases motor torque and reduces motor speed
The gear ratio of the gearbox has different gear ratios for you to choose, and the efficiency of the gearbox is also related to the gear.
Output torque = raw torque * gear ratio * gearbox efficiency
output speed = original speed / gear ratio
