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

About DC brushed motors:
DC brushed motors are most commonly used motors on the market.
It has electrical brush inside, and it has positive and negative
pins (+ and -)
DC motor’s speed can be controlled with different gear ratios, or
PWM control. (Pulse-Width Modulation)
With gearbox torque boost, DC motor can reach much higher torque,
compared to motor’s original torque.
Advantage of DC brush motors:
1. Cheap price
2. Small size
3. Easy to connect, easy to use
4. Commonly used
5. Fast speed
6. High efficiency (compared to stepper motor)
DC motor with gearbox:
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
