About this 3D model

2021/12/20 Several weeks ago I DIY the N20 type geared motor in serial connection. And then I changed the serial connection to a parallel configuration. The mini N20 type geared motor can provide very powerful output torque. Today I use two square motors and the stacked gearbox to make an extremely powerful stacked geared motor. In theoretical it can provide very powerful torque. It can be used in daily life at a very low cost. Hope it will give you some idea or help.Please like and share with your friend. Thanks a lot. Have a nice day. https://youtu.be/UnaMs47RAvI
