The power requirements of the motor are that the maximum input voltage is less than 13. 2V and the maximum current is 38A. Regarding the parameters of the motor performance, the maximum power is 500W, and the maximum The output speed is 50000RPM, and the KV value is 3600KV. The motor torque parameters have not been tested yet, but the power of 500W is enough. It can be paired with a suitable reduction gearbox to reduce the speed and increase the torque. Why do we use this transaxle instead of the one that comes with Lego? The drive axle of Lego bricks has sliding friction and a large friction coefficient. 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. The only one problem is basically caused by hitting things, causing the building blocks to be separated from the metal parts and damaged.
