The invention relates to the technical field of motor controllers, in particular to a motor controller, a power assembly and a vehicle. The motor controller comprises a three-phase bridge arm, a capacitor module and a heat dissipation plate group. The capacitor module comprises a capacitor shell and a capacitor core package. The capacitor shell comprises a first sub-shell and a second sub-shell. The first sub-shell and the second sub-shell form an accommodating cavity along a gap in the first direction, and the accommodating cavity is used for accommodating a capacitor core package. The three-phase bridge arm comprises a plurality of power modules, the heat dissipation plate group is used for dissipating heat for the plurality of power modules, the heat dissipation plate group is used for being fixedly connected with one side, deviating from the capacitor core package, of the first sub-shell in the first direction, and a gap between the heat dissipation plate group and the first sub-shell in the first direction is used for forming a cooling liquid flow channel. The first sub-shell comprises two flow channel openings, and the two flow channel openings are used for communicating with the cooling liquid flow channel. The cooling liquid flow channel in the motor controller exchanges heat with the capacitor core package through the first sub-shell, so that the heat exchange efficiency of the capacitor core package can be improved.
