The power requirements of the motor are that the maximum input voltage is less than 13.2V and the maximum current is 38A.

When the load is small, the bricks will wear out after continuous rotation for several minutes or more than ten minutes. When the load is large, the friction will be more serious. There may also be severe heat that causes the bricks to melt and be damaged. In response to these problems, the drive axle I designed has built-in ball bearings, which greatly reduces the friction coefficient. The heat generated by friction is very small and almost no heat is generated. Therefore, we have never encountered metal heating in this case.\u003c\/li\u003e\n\u003cli\u003eThe only one problem is basically caused by hitting things, causing the building blocks to be separated
