Heat Transfer Model on 120kW BLDC’s Motor Integrated Controller

Heat conditions on components even on systems will impress a lifetime of components and affect all systems. On BLDC motor system with power capacitance of 120 kW will simulate the 3dimension (3D) model as divided into 2 components which are BLDC Motor 120 kW and Infineon IGBT type FF1400R12IP4. The simulation does in full power situation. BLDC Motor 120 kW model using 1 slot on stator with water cooling and 1 pole magnet on rotor. The stator winding will become heat source, with maximal power value is 1/9 of power rate, while IGBT model uses 3 pcs of IGBT arranged in cooling plate. Each IGBT will become a heat source with maximal input power to system being 40 kW. Simulation time run is t=3600s. The simulation base on online simulation using SimScale, generated the thermal change on each supporting component of the system. Final condition after 3 situation simulation sequentially of BLDC Motor and IGBT will generate final temperature on face133, face193, face177 and face185 of stator winding is 442.68°K, 439.75°K, 430.6°K and 424.59°K On face1602, face5562 and face84 of IGBT is 854.21°K, 663.74°K and 635. 78°K.
