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 can boost motor’s torque, and reduce motor’s speed
We have different gear ratios for you to choose, also gearbox’s efficiency is related to gear levels.
Output torque=original torque*gear ratio* gearbox efficiency
Output speed= original speed/gear ratio
