Abstract: This application relates to motor control unit technologies, and in particular, to a motor control unit, a powertrain, and a vehicle. The motor control unit includes a three-phase bridge arm, a capacitor module, and a heat dissipation panel group. The capacitor module includes a capacitor housing and a capacitor core package, and the capacitor housing includes a first sub-housing and a second sub-housing. A gap between the first sub-housing and the second sub-housing forms an accommodating cavity in a first direction, and the accommodating cavity is used to accommodate the capacitor core package. The three-phase bridge arm includes a plurality of power modules. The heat dissipation panel group is configured to dissipate heat for the plurality of power modules.
