Abstract
Heat condition on components even on systems will impress a lifetime of components and it will affect all of systems. On BLDC motor system with power capacitance 120 kW will simulate the 3 dimension (3D) model as divide onto 2 components which is BLDC Motor 120 kW and Infineon IGBT type FF1400R12IP4. The simulation do on 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 per 9 from power rated, while IGBT model using 3 pcs of IGBT arranged in cooling plate. Each of IGBT will become heat source with maximal input power to system is 40 kW. Simulation time run is t = 3600s. The simulation base on online simulation using SimScale, generated the thermal change on each of supporting component on 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.
