Abstract: The present disclosure provides an intelligent power module, a motor controller and a vehicle. The intelligent power module includes a power electronic device, a capacitor, a driving board, a heat sink disposed between the power electronic device and the capacitor, and a fixing plate disposed on an outer side of the power electronic device. The intelligent power module is configured such that key components are secured to each other to prevent mechanical damage due to vibration.
