  • Water cooled rotor

  • KULI-System

    This subsystem demonstrates a possibility to model an electric motor with fluid cooling of both stator and rotor.

    The built-in model of an electric motor in KULI assumes that the stator is (optionally) fluid-cooled whereas the rotor is not. The rotor is only connected to the stator via conduction. Some e-motor concepts however also include a water cooled rotor. The attached subsystem provides a method with which such a configuration can be modeled. The main idea is to connect the heat conduction connector of the rotor with a point mass in the fluid circuit that models the coolant within the rotor. The point mass itself has a very high heat transfer coefficient. The heat conduction component modeling the heat transfer between the rotor and the water has a heat conductivity coming from CFD analysis.
