——DC GEAR MOTOR PRINCIPLE
The internal principle of the gearbox of the reducer is to use all levels of gear transmission to achieve the purpose of speed reduction. The reducer is composed of gear pairs at all levels. For example, using a small gear to drive a large gear can achieve the purpose of mechanical deceleration. The structure can greatly increase the mechanical deceleration and increase the torque. When the output speed of the motor is input from the driving shaft, the pinion gear is driven to rotate, and the pinion gear drives the large gear movement, and the number of teeth of the large gear is more than that of the small gear. The speed of the large gear is slower than that of the small gear. The output shaft output, thereby playing the role of output deceleration. As a power transmission mechanism, the reducer uses a gear speed converter to reduce the number of revolutions of the motor (motor) to the desired number of revolutions and obtain a large torque. In the current machinery industry, among the mechanisms used to transmit power and motion, the application of the reducer is the most extensive one!

——DC GEAR MOTOR CALCULATION
Gear Motor Torque=Driving motor torque*Reduction ratio*Gearbox efficiency
For example, our model DM-12SSN2000315000-150K
From our datasheet table, we can see the Driving motor torque at 3v 15000rpm is about 3gf.cm, the gear ratio is 100;
for the gearbox table, we can see the efficiency for 150 gear ratio(5 stage) is about 59%
So the gear motor torque is about 3*100*59%, that is about 117gf.cm.
Gear Motor Speed=Driving motor speed/Reduction ratio
For example, our model DM-37RS35300126000-90K, the driving motor speed is 6000rpm at 12v, this is normally free load.
For output, the no load or free load speed is 6000/90, that is about 67rpm. While loading, the reasonable range is 75%-80%
it means to rated speed or load speed is about 50-53rpm
