Abstract: A motor controller includes a housing, a power circuit board, and a control circuit board. The housing includes a first mounting platform, a second mounting platform, and a side wall. There is a height difference between the first mounting platform and the second mounting platform. The first mounting platform is disposed on an upper part of the side wall, and the second mounting platform is disposed on a middle part of the side wall. The second mounting platform is disposed on one side of the first mounting platform. The first mounting platform and the side wall form an upper chamber, and the control circuit board and the power circuit board are disposed in the upper chamber. The control circuit board is closer to the first mounting platform than the power circuit board. The second mounting platform and the side wall form a lower chamber communicating with the upper chamber.
