Abstract: A rotation apparatus comprises a machine base and a stator. The machine base comprises a driving end intermediate support board and a non-driving end intermediate support board disposed parallel along the length direction of the machine base. Inner holes used for supporting the stator are separately provided in the driving end intermediate support board and the non-driving end intermediate support board. The inner holes in the driving end intermediate support board are asymmetrical on the top and the bottom. The vibration of the rotation apparatus can be effectively reduced, the output power is improved, and a good cooling effect is provided.
