Stack N20 geared motor (Increase speed without decreasing torque, world first-time try)

2021/10/24

Recently I am interested in the N20 geared motors. They are series motors in fact. The N20 motor connect to a whole metal gearbox that changes the output speed. By decreasing the speed, the output torque is increased. The normal N20 motor has about 0.4 mN.m or 4 g.cm Stall torque. By decreasing the speed 250 times, the torque can increase 250 times that is about 1 Kg.cm, or 1 mN.m. Someone uses the parallel motor connection that increases the torque. But I have not seen others using the series motor connection, especially the series geared motor connection. What will happen? Is the torque increase or speed increase? I will do the experiment and explain the mechanism. Hope it will give you some help and like it. Please share it with your friends. Thanks a lot.

This is maybe the world's first-time stack N20 geared motor together experiment. If everything is optimized, the torque of the final output will not change but the speed can be increased. Theoretically, we can in
