High Speed DC Gear Motor N20 Gearbox Motor Speed Ratio Can Be Selected

High-Speed DC Gear Motor N20 Gearbox Motor Speed Ratio Can Be Selected

Description

This is a N20 DC motor with a 10*12 gearbox.
The N20 DC motor is also a brushed DC motor and has a no-load speed of about 15,000 RPM for a single motor.
When the motor is connected to a gear box, it will run slower and the torque will be higher.

Customers can choose the gear ratio according to their needs. The gear ratios available for gearboxes are: 2:1, 5:1, 10:1, 15:1, 20:1, 30:1, 36:1 , 50:1, 63:1, 67:1, 89:1, 100:1, 110:1, 120:1, 150:1, 172:1, 210:1, 250:1, 275:1, 298 :1, 380:1, 420:1, 500:1, 600:1, 1000:1.
Gear ratios below 420:1 (including 420:1) have a gearbox length of 9mm.
Gear ratios over 420:1 have a gearbox length of 12 mm.

About DC brushed motors

DC brushed motor is the most commonly used motor in the market.
The DC motor has brushes inside, l positive and negative pins (+ and -).
The speed of a DC motor can be controlled with different gear ratios or with PWM (Pulse Width Modulation)
With the torque boost of the gearbox, the DC motor can reach higher torque compared to the original torque of the motor.
