Abstract: A motor controller includes a first box body including a first surface and a second surface opposite to each other along a thickness direction of the first box body, and includes a cooling water passage that includes a first opening on the first surface. An IGBT module is disposed on the first surface and disposed in the cooling water passage. The motor controller further includes a capacitor disposed on the second surface and connected to the IGBT module, and includes a housing and a capacitor core disposed in the housing. The housing has a heat dissipation opening configured to expose the capacitor core. The motor controller further includes a heat conductor covering the heat dissipation opening. One side of the heat conductor is in contact with the capacitor core, and the other side is in contact with an outer wall surface of the cooling water passage.
