The invention relates to the technical field of motor controllers, in particular to a motor controller and a power assembly. The motor controller comprises a liquid cooling radiator and an integrated assembly. The liquid cooling radiator is used for cooling the plurality of power modules. Each power module comprises at least one power tube, the integrated assembly comprises an integrated shell and a capacitor core body, and the integrated shell is used for accommodating the capacitor core body. The integrated shell comprises two cooling liquid through holes, and the two cooling liquid through holes are used for being communicated with the liquid cooling radiator. In the first direction, the liquid cooling radiator and the integrated shell are arranged in a stacked mode, and each cooling liquid through hole penetrates through the integrated shell. In the second direction, the distance between the two cooling liquid through holes is smaller than the length of the liquid cooling radiator. Along the third direction, the aperture of each cooling liquid through hole is smaller than the width of the cooled radiator. The motor controller is compact in layout and small in occupied space.
